Let's break down the foundation methods before we dive into AI enhancements. Understanding these basics helps you appreciate what AI brings to the table.
This is Position Sizing 101. You risk the same percentage on every trade regardless of anything else. The formula is simple: Position Size = (Account × Risk %) / Stop Distance.
Here's how it works in practice. You've got $100,000, risk 1% per trade, and your stop is 5% away. Your position size becomes ($100,000 × 0.01) / 0.05 = $20,000. Every trade, same calculation.
The good news? It's dead simple and keeps your risk consistent as your account grows or shrinks. The bad news? It treats every trade the same. Your highest-conviction setup gets the same size as that sketchy pattern you're not even sure about. It's like using a hammer for every job - functional, but hardly optimal.
This method actually considers market conditions. Instead of fixed stops, you use Average True Range (ATR) to adjust for volatility. The formula: Position Size = (Account × Risk %) / (ATR × Multiplier).
Let's say your account is $100,000, you risk 1%, ATR is $500, and you use a 2x multiplier. Your position becomes ($100,000 × 0.01) / ($500 × 2) = $1,000. When volatility is low, ATR is smaller, so your positions get larger. When volatility spikes, positions shrink automatically.
This beats fixed percentage because it adjusts for market conditions. Calm markets get bigger positions, volatile markets get smaller ones. But here's the problem - ATR looks backward. You're sizing for yesterday's volatility, not tomorrow's. Still ignores signal quality and portfolio context too.
Kelly sizing accounts for your edge quality, which is revolutionary compared to fixed methods. If your win rate or reward/risk ratio improves, Kelly automatically increases your sizing. Edge gets worse? Sizing decreases. It's responsive to strategy performance.
But Kelly has some brutal assumptions. It assumes you know your exact win rate and reward/risk ratio, that these stay constant, and that you can handle massive drawdowns without psychological damage. In crypto, where conditions change rapidly, these assumptions fall apart quickly.
Most traders who use Kelly go with fractional Kelly - maybe 25% to 50% of the full Kelly recommendation. This reduces the drawdowns to more manageable levels while still capturing most of the growth benefits.
The simplest portfolio approach: divide your capital equally across all positions. Got $100,000 and want 10 positions maximum? Each gets $10,000. Done.
Equal weighting forces diversification and keeps you from going all-in on your latest obsession. It's also dead easy to manage - no complex calculations needed. But it ignores everything about risk differences between assets. Treating Bitcoin and some random altcoin as equally risky? That's not going to end well. Plus, it completely misses optimization opportunities based on signal quality or correlations.
This is where things get interesting. AI doesn't just follow rules - it processes multiple factors simultaneously and adapts to changing conditions in ways humans simply can't match.
Traditional methods look at maybe one or two factors. AI considers everything at once. Signal confidence from your strategy? Check. Predicted volatility for the next few days? Yep. How correlated this new position is with your existing holdings? Absolutely. Current drawdown level? Of course. Recent win/loss streaks? You bet.
No human could practically combine all these factors in real-time for every trade. You'd spend more time calculating than trading. AI does it instantly, adjusting position size up for high-confidence trades in favorable conditions, down for marginal setups during uncertain times.
Here's a game-changer. Traditional sizing uses historical volatility - ATR, standard deviation, whatever. You're essentially driving by looking in the rearview mirror. AI predicts future volatility using machine learning models that consider market microstructure, options flows, news sentiment, and technical patterns.
Instead of sizing for last week's volatility, you're sizing for next week's expected volatility. About to enter a position right before earnings or a Fed meeting? AI sees the volatility spike coming and sizes accordingly. Market looks calm but technical patterns suggest a breakout? Position size adjusts for the expected move.
Not all trade setups are created equal, but traditional sizing treats them the same. AI evaluates each trade's quality by analyzing historical performance of similar setups, confluence of multiple signals, current market context, and timing quality.
Your A+ setups - multiple confirmations, favorable context, perfect timing - might get 1.5x your standard size. B-grade setups get normal sizing. C-grade marginal patterns get half size or maybe you skip them entirely. This aligns your risk with opportunity quality in ways fixed percentage never could.
Here's something most traders completely miss. You take a full-size Bitcoin position, then see Ethereum setting up nicely. Traditional sizing says take another full position. AI says hold up - these are highly correlated. Taking both at full size creates concentrated risk that looks like diversification.
AI calculates the correlation between your new position and existing portfolio, then adjusts accordingly. High correlation? Reduce the new position size. Negative correlation that provides hedging? Maybe increase it slightly. Your portfolio risk stays controlled while maximizing opportunities.
Human psychology during drawdowns is terrible. We want to trade bigger to recover faster, which usually makes things worse. AI does the opposite - reduces size during drawdowns to protect remaining capital, then gradually increases as recovery occurs.
This isn't about being conservative. It's about survival. The difference between a 20% drawdown and a 50% drawdown isn't just comfort - it's the difference between needing a 25% return to recover versus a 100% return. AI keeps drawdowns manageable by adjusting size when things aren't going well.
Let's dive into specific AI approaches that are transforming position sizing. Each has its strengths and ideal use cases.
Traditional Kelly assumes your win rate and reward/risk ratio are known and constant. ML Kelly uses machine learning to estimate these parameters dynamically based on current market conditions. Instead of using your overall historical stats, it predicts what your win rate and reward/risk will be for this specific trade in current conditions.
The model considers factors like volatility regime, market sentiment, your recent performance, and setup characteristics to adjust the Kelly inputs in real-time. Bull market with low volatility? Your win rate prediction might increase. Choppy market with high correlation across assets? Win rate prediction decreases, sizing adjusts accordingly.
This creates Kelly sizing that actually adapts to changing conditions rather than assuming everything stays the same forever. You get the mathematical optimization benefits of Kelly with the responsiveness to handle dynamic markets.
This is where AI gets really interesting. Reinforcement learning agents learn optimal sizing strategies by trying thousands of different approaches in simulated environments and measuring the outcomes. The agent might try conservative sizing, aggressive sizing, volatility-responsive sizing, or completely novel approaches humans wouldn't think of.
The learning process optimizes for whatever objective you define - maybe maximize Sharpe ratio while keeping maximum drawdown under 15%. The agent discovers which sizing strategies achieve these goals best through trial and error across various market conditions.
What's fascinating is these agents sometimes discover counter-intuitive strategies. Maybe sizing up during certain types of drawdowns actually improves long-term results. Or reducing size during win streaks prevents overconfidence disasters. The AI finds patterns in the relationship between sizing and outcomes that humans miss.
Deep learning models can capture complex nonlinear relationships between market conditions and optimal position size. The neural network takes inputs like signal characteristics, market regime indicators, portfolio state, and recent performance, then outputs a recommended position size as a percentage of your standard.
These models excel at finding subtle patterns. Maybe certain combinations of volatility, sentiment, and technical patterns call for specific sizing adjustments that aren't obvious from any single factor. The neural network learns these interactions from historical data and applies them to new situations.
The key advantage is handling complexity. Traditional rules-based sizing quickly becomes unwieldy when trying to account for multiple factors. Neural networks handle dozens of inputs naturally, finding the optimal sizing decision even when the relationships are highly nonlinear.
Why choose one approach when you can combine the best of multiple models? Ensemble sizing uses several different models - maybe a volatility-based model, a Kelly-based model, and a neural network - then combines their recommendations into a final decision.
The combination might be a simple average, a weighted average based on recent performance of each model, or even another AI model that learns how to optimally combine the base models. This approach is robust against any single model failing or performing poorly in certain conditions.
Ensemble methods often outperform individual models because they capture different aspects of the sizing decision. One model might be better at volatility adjustment, another at signal quality scoring, and a third at portfolio context. Combining them gives you the benefits of all approaches.
Position sizing handles individual trades. Rebalancing manages your overall portfolio allocation. Without systematic rebalancing, your carefully planned allocations slowly drift until they bear no resemblance to your original strategy.
Here's what happens without rebalancing. You start with a nice balanced portfolio - maybe 25% Bitcoin, 25% Ethereum, 25% Solana, and 25% stablecoins. Bitcoin doubles while everything else stays flat. Now you're 40% Bitcoin, 20% everything else.
Your risk profile just changed completely. You started with balanced exposure and ended up concentrated in the most volatile asset. If Bitcoin crashes 50% from here, your portfolio takes a 20% hit even though the other assets are unchanged. The diversification you thought you had? Gone.
This drift happens continuously in volatile markets like crypto. Winners grow to dominate your portfolio while losers shrink but still create drag. Without active rebalancing, your allocation becomes whatever random outcome recent market movements created.
Calendar rebalancing happens at fixed intervals - weekly, monthly, quarterly. It's simple and systematic, but might rebalance when markets are trending strongly (selling winners too early) or miss periods when rebalancing would be most beneficial.
Threshold rebalancing triggers when allocations drift beyond predetermined limits. Maybe you rebalance when any asset moves more than 5% from its target allocation. This responds to actual portfolio changes rather than arbitrary dates, but requires more monitoring.
Tactical rebalancing considers market conditions and opportunities. Maybe you hold off on rebalancing during strong trends but accelerate it during volatile, range-bound periods. More complex but potentially more profitable.
Here's the beautiful thing about disciplined rebalancing in volatile markets - it can actually generate returns on its own. The mechanism is systematic buying low and selling high. Asset A rises and becomes overweight, so you sell some and buy underweight Asset B. Then A falls and B rises, so you sell B and buy A. Net effect: you bought A low and sold high, bought B low and sold high.
This rebalancing bonus works best with volatile, mean-reverting assets that have low correlation. It fails in strong trending markets where you end up selling winners too early and buying losers too early. Transaction costs can also eat the bonus if you rebalance too frequently.
The key is finding the sweet spot - frequent enough to capture volatility, infrequent enough to avoid excessive costs, and smart enough to avoid rebalancing against strong trends.
AI transforms rebalancing from mechanical rules to intelligent, adaptive portfolio management that considers market conditions, costs, and opportunities.
Traditional rebalancing uses fixed thresholds - maybe rebalance when any asset drifts 5% from target. AI makes these thresholds dynamic based on current conditions. In volatile markets, thresholds widen to avoid excessive trading. In calm markets, they narrow to maintain tighter allocation control.
The AI considers transaction costs, expected volatility, correlation structure, and market regime when setting thresholds. About to enter a volatile period? Thresholds expand automatically. Market looking stable with good liquidity? Thresholds contract to capture more rebalancing opportunities.
This prevents the common problems of fixed thresholds - over-trading in volatile periods and under-rebalancing in stable periods. The system adapts to optimize the rebalancing frequency for current conditions.
Instead of reacting to drift after it happens, AI anticipates when rebalancing will be needed and acts proactively. Short-term prediction models estimate likely asset movements over the next few days or weeks, then calculate expected portfolio drift.
If the models predict significant drift, the system can rebalance early when conditions are favorable - good liquidity, tight spreads, low volatility. This avoids rebalancing during chaotic periods when execution costs are high and market impact is significant.
The system also knows when NOT to rebalance. If predictions suggest a strong trend is just getting started, it might delay rebalancing to avoid selling winners prematurely. The key is optimizing rebalancing timing based on expected future conditions, not just current drift.
For taxable accounts, AI considers tax implications in every rebalancing decision. It tracks cost basis, holding periods, and tax-loss harvesting opportunities to minimize the tax drag on returns. Short-term gains get avoided when possible, tax-loss harvesting gets prioritized, and wash sale rules stay compliant.
The system might deliberately avoid rebalancing positions with large short-term gains until they become long-term, or accelerate rebalancing of positions with losses to harvest tax benefits. Complex, but the AI handles it automatically while optimizing both portfolio allocation and tax efficiency.
Every rebalance costs money in spreads, fees, and market impact. AI minimizes these costs through intelligent execution. It batches multiple adjustments together, uses limit orders when time permits, times execution for optimal liquidity, and accepts partial rebalancing when full rebalancing is too expensive.
The system learns which exchanges and times of day offer the best execution, then routes rebalancing trades accordingly. It might use a stablecoin as an intermediate currency to reduce the number of trades needed, or utilize cross-exchange arbitrage opportunities during rebalancing.
AI doesn't just look at portfolio drift - it considers the broader market context. Correlation breakdown between assets might trigger accelerated rebalancing to restore diversification benefits. Volatility spikes might pause rebalancing until conditions stabilize. Tax-loss opportunities might override normal rebalancing rules.
Major news events, technical breakouts, or regime changes all influence rebalancing decisions. The AI adapts the rebalancing strategy to current conditions rather than blindly following fixed rules that might be inappropriate for the moment.
Moving from theory to practice. Here are the main implementation approaches, each with different trade-offs between control, speed, and automation risk.
This is the safest way to start. The AI calculates recommended position sizes and presents them to you for review and approval. You maintain complete control over every trade while benefiting from AI's multi-factor analysis.
The process is straightforward: AI analyzes the setup, considers all relevant factors, and suggests a position size. You review the recommendation, maybe override it if you disagree, then execute manually. Slow but safe, especially while you're learning to trust the AI's recommendations.
The main advantage is keeping human judgment in the loop. You catch obvious errors, override in unusual circumstances, and gradually build confidence in the system. The downside is speed - you need to be available to review every recommendation, which defeats the purpose if you're trying to trade automatically.
This strikes a balance between control and efficiency. The AI calculates position sizes automatically and generates alerts with one-click approval. You get a notification showing the trade setup, recommended position size, and reasoning. Click approve, and the system executes.
This is much faster than manual while maintaining oversight. You can set parameters for automatic approval of smaller positions while requiring manual approval for larger ones. Emergency stops and position limits provide additional safeguards.
The risk is rubber-stamping without proper review. It's easy to click approve without really evaluating the recommendation, especially during busy periods. Setting proper position limits and review thresholds is crucial.
Maximum speed and efficiency, but requires robust safeguards. The AI calculates position sizes and executes trades automatically within predefined parameters. You review results afterward rather than approving trades beforehand.
This approach shines for high-frequency strategies or when trading across multiple time zones. The system never sleeps, never gets emotional, and executes instantly when conditions align. But errors execute automatically too, so safeguards are critical.
Essential safeguards include maximum position size limits (never risk more than X% per trade), total exposure limits (never have more than Y% deployed), sanity checks (alert if unusual sizes calculated), and kill switches (stop everything if certain conditions occur).
Successful implementation requires connecting multiple systems. Your trading platform needs API access for position data and order execution. Risk management systems need real-time position tracking and portfolio risk calculation. Journaling systems should record sizing decisions and track their impact on results.
The AI needs data feeds for market conditions, volatility indicators, correlation calculations, and signal generation. All these components must work together seamlessly, with proper error handling and failsafes throughout.
Testing is crucial before going live. Backtest the sizing models extensively, paper trade to verify execution, and start with small position limits while building confidence. The goal is robust, reliable automation that enhances rather than complicates your trading.

Position sizing IS risk management, but it doesn't operate in isolation. Integration with other risk controls creates comprehensive protection that keeps you trading through all market conditions.
Your position size and stop loss work together to determine your actual dollar risk per trade. The relationship is mathematical: Position Size = Target Dollar Risk / Stop Distance in Dollars. Change one, and the other must adjust to maintain consistent risk.
AI optimizes both simultaneously. It suggests stop loss levels based on technical analysis, then calculates the position size that achieves your target dollar risk. Tight stops allow larger positions for the same risk. Wide stops require smaller positions. The key is maintaining consistent dollar risk regardless of stop placement.
This coordination prevents the common mistake of using technical stops with position sizes calculated elsewhere. Your stop might be technically perfect, but if it creates a 5% account risk when you only wanted 1%, you've got a problem. AI solves this by considering both elements together.
Individual position risk is just one piece of the puzzle. Portfolio risk depends on how positions interact - correlation, timing, total exposure. AI calculates correlation-adjusted portfolio risk and refuses to add positions that would push total risk beyond your limits.
Maybe you want maximum 10% portfolio risk at any time. You've got three positions with 2% risk each, but they're highly correlated. Your actual portfolio risk might be 5% instead of 6% if correlations are perfect. AI sees this and allows larger position sizes. If correlations are low, portfolio risk might be only 3%, allowing room for additional positions.
This prevents the false diversification trap where you think you're spreading risk but actually concentrating it in correlated assets. AI maintains true portfolio-level risk control.
Leverage multiplies everything - returns, losses, and the impact of position sizing decisions. A 2% position size with 5x leverage creates 10% effective exposure. AI adjusts base position sizes when using leverage to maintain consistent risk levels.
The calculation is straightforward: if you normally risk 1% per trade and use 3x leverage, your base position should be roughly 0.33% to maintain similar risk. But AI can optimize this further by considering volatility differences between leveraged and unleveraged positions.
Leveraged positions often behave differently due to funding costs, forced liquidations, and increased volatility. AI factors these differences into sizing decisions rather than using simple mathematical adjustments.
Risk management must adapt to performance. During winning periods, you can maintain normal risk levels. During drawdowns, risk should decrease progressively to protect remaining capital and prevent ruin.
AI implements systematic drawdown-responsive sizing. Maybe 0-5% drawdown maintains normal sizing, 5-10% reduces to 75% of normal, 10-15% drops to 50%, and beyond 15% requires trading suspension and strategy review. The exact thresholds depend on your risk tolerance and strategy characteristics.
This isn't about being conservative - it's about survival math. A 50% drawdown requires a 100% return to recover. By reducing risk during drawdowns, you prevent small problems from becoming account-threatening disasters.
Counterintuitively, AI often reduces position sizes during extended winning streaks. Human psychology leads to overconfidence during wins, but statistically, extreme streaks often precede reversals. Mean reversion is powerful in trading.
The system tracks streak length and gradually reduces sizing after extended runs of winners. This isn't pessimism - it's recognizing that nothing goes up forever, and protecting profits when overconfidence risk is highest. Position sizes return to normal gradually as the streak ends.

Learning from others' mistakes is cheaper than making them yourself. Here are the critical errors that destroy trading accounts and how to avoid them.
The biggest mistake is having no systematic approach to position sizing. Traders make sizing decisions based on gut feeling, recent performance, or how excited they are about a particular trade. This leads to inconsistent risk, emotional decision-making, and eventual ruin.
The cost is enormous. Without systematic sizing, you'll inevitably have a few trades that risk too much at the worst possible time. Maybe you get overexcited about a setup and risk 10% instead of your usual 2%. If that trade goes wrong - and it will eventually - you've created a massive setback that could take months to recover from.
The solution is implementing ANY systematic approach immediately. Even simple fixed percentage sizing beats emotional sizing. You can optimize later, but you need rules now.
Many traders size positions to feel important or grow their accounts faster. They risk 5-10% per trade thinking it'll accelerate their journey to profitability. This is gambling disguised as trading, and it ends predictably.
The mathematics are brutal. Risk 10% per trade and you're essentially guaranteed to eventually hit a losing streak that destroys your account. Maybe not this month, maybe not next month, but eventually. The few traders who get lucky early often give it all back when regression to the mean kicks in.
Professional traders rarely risk more than 2% per trade, with 1% being more common. This isn't because they're conservative - it's because they understand survival math. You can't compound returns if you don't survive long enough to compound.
This mistake looks like diversification but acts like concentration. Traders take full positions in Bitcoin, Ethereum, and three other altcoins, thinking they're spreading risk. In reality, they're taking five correlated bets on the same underlying theme - crypto market direction.
When crypto sells off, all positions decline together. The diversification was an illusion. Your 5% account risk across five positions becomes 5% concentrated risk when correlations spike to 0.9 during stress periods.
The solution is correlation-aware sizing. Calculate how your positions interact, not just their individual risks. AI excels at this because it considers correlation dynamically rather than using historical averages that fail when you need diversification most.
Using the same position size in calm and volatile markets creates inconsistent dollar risk. A 2% position in Bitcoin when ATR is $500 creates very different risk than 2% when ATR is $2000. Your "consistent" sizing actually creates wildly different risk levels.
AI solves this by adjusting for predicted volatility rather than historical volatility. About to enter a position before a major news event? The system sees the volatility spike coming and sizes accordingly. This creates consistent risk across different market regimes.
The most psychologically damaging mistake is increasing position sizes during drawdowns to "get even" faster. This feels rational - bigger positions mean faster recovery - but it's actually the fastest way to turn a manageable drawdown into complete ruin.
The mathematics work against you. During drawdowns, your strategy isn't working well. Increasing size means betting bigger on something that's currently failing. Instead of giving your edge time to play out, you're amplifying the very conditions causing the drawdown.
AI prevents this by systematically reducing size during drawdowns. It's programmed to protect capital when things aren't going well, then gradually increase size as performance improves. This aligns sizing with strategy performance rather than emotional desire for quick recovery.
Frequent rebalancing without considering costs can eat returns. Every rebalance involves spreads, fees, and market impact. In crypto, these costs can be substantial, especially for smaller accounts or less liquid assets.
AI optimizes rebalancing frequency by calculating the expected benefit versus costs. Maybe perfect rebalancing would improve returns by 2% annually, but transaction costs would be 3%. The AI skips the rebalance. When benefits clearly exceed costs, it executes efficiently.
Most professional traders risk 0.5-2% per trade, with beginners starting even lower. I usually recommend 0.5-1% until you've demonstrated consistent profitability over several months. More aggressive traders might go to 2%, but rarely higher without exceptional win rates and risk/reward ratios.
The right percentage depends on your specific edge characteristics. A strategy with 70% win rate and 3:1 reward/risk can handle larger sizing than one with 45% wins and 1.5:1 reward/risk. AI can optimize this based on your actual performance data rather than generic recommendations.
Optimal rebalancing frequency depends on volatility and transaction costs. For most crypto portfolios, I've found threshold-based rebalancing works better than calendar-based. When any allocation drifts 5-10% from target, it's usually time to rebalance.
AI can determine optimal thresholds for your specific portfolio by analyzing historical volatility, correlation patterns, and transaction costs. Generally, monthly review with threshold triggers works well for most investors, but active portfolios might need weekly attention during volatile periods.
AI doesn't perfectly predict the "right" size - that's impossible. But it makes significantly better sizing decisions than fixed-percentage approaches by incorporating more relevant factors. Predicted volatility, signal quality, correlation analysis, portfolio context, and market regime all influence the decision simultaneously.
The performance improvement comes from optimization over time. AI learns from outcomes, adjusts models based on results, and gradually improves sizing decisions. It won't eliminate losses, but it'll optimize the risk/reward relationship across many trades.
Absolutely, within limits. Sizing up for A-grade setups and down for marginal trades aligns risk with opportunity quality. However, caps are essential - even maximum conviction shouldn't exceed your overall risk limits by more than 50-100%.
The key is objective conviction scoring rather than emotional excitement. AI helps by evaluating signal quality based on historical performance of similar setups, confluence of multiple indicators, and market context favorability. This prevents the human tendency to feel high conviction about every trade.
Several platforms offer AI sizing without programming requirements. Shrimpy and 3Commas provide automated rebalancing, Thrive offers AI-assisted sizing recommendations, and Cryptohopper includes strategy-based sizing features.
Start with basic features like automated rebalancing or simple volatility adjustments. As you become comfortable with the systems and see results, you can increase sophistication. The key is starting with something rather than waiting for the perfect solution.
They're mathematically linked through your target dollar risk. Position Size = Dollar Risk / Stop Distance. Tight stops allow larger positions for the same risk; wide stops require smaller positions. AI optimizes both together rather than treating them as separate decisions.
The system suggests stop placement based on technical analysis, then calculates position size to achieve your target risk level. This prevents the common mistake of using technically perfect stops that create inappropriate risk levels for your account size.
AI position sizing and portfolio rebalancing transform trading's most critical yet overlooked element. Position sizing determines survival - too large leads to ruin, too small wastes opportunity. Traditional methods provide foundations but miss crucial optimization opportunities that AI captures through multi-factor analysis.
Machine learning improves sizing by simultaneously considering signal confidence, predicted volatility, portfolio correlation, current drawdown levels, and market regime characteristics. Specific AI approaches include enhanced Kelly estimation, reinforcement learning, neural network position sizing, and ensemble methods combining multiple models.
Portfolio rebalancing maintains target allocations and can generate returns through systematic buying low and selling high. AI-powered rebalancing uses intelligent threshold detection, predictive timing, tax optimization, and transaction cost minimization to improve outcomes.
Implementation ranges from manual AI assistance to full automation, with appropriate safeguards at each level. Integration with stop losses, portfolio risk management, leverage considerations, and drawdown protocols creates comprehensive risk control.
The most common mistakes include having no systematic approach, sizing too large, ignoring asset correlations, not adjusting for volatility, increasing size during drawdowns, and ignoring transaction costs. Available tools range from simple rebalancing platforms to sophisticated custom solutions.
Success requires understanding the mathematical foundations, implementing systematic approaches, and continuously optimizing based on results. AI doesn't eliminate risk but optimizes the relationship between risk and opportunity across many trades and changing market conditions.
Thrive brings AI-powered position sizing to your trading workflow without the complexity of custom development. The system provides dynamic size recommendations that adjust for volatility, signal quality, and portfolio context automatically.
