What Is Conviction?
Conviction is the degree of confidence a trader has in a particular trade thesis. High conviction means multiple confluences align, the risk-reward is exceptional, and the setup matches your proven edge. Low conviction means the signal is marginal, the setup is suboptimal, or key confirmation is missing.
How Conviction Works
Conviction should directly influence position sizing: high-conviction setups warrant larger positions (closer to your maximum risk allocation), while low-conviction setups warrant smaller positions or no trade at all. This creates a natural weighting system where your best ideas have the most capital behind them and your weakest ideas have the least.
Why It Matters for Traders
One of the most common mistakes is treating all trades equally regardless of conviction. A trader who risks 2% on every trade — whether it's a textbook setup with 5 confluences or a marginal signal — leaves significant performance on the table. Professional traders size up on high-conviction opportunities and size down (or pass) on low-conviction ones, concentrating capital where the edge is strongest.
How Perps Traders Use This
For CEX perpetual futures, treat conviction as context around entries, exits, and risk, not as a standalone signal. Pair it with funding, open interest, and liquidation heat so one indicator does not drive the whole book.
Formula and Worked Example
Example numbers only (not a live quote).
If your account equity is $10,000 and you risk 0.5% per idea, the cash risk budget is $50. With a stop 1% away from entry on a linear USDT-margined perp, notional size is about $5,000 before leverage optics. Size from stop distance first, then pick leverage that fits the margin mode.
Common Mistakes
- Treating a single print of conviction as a trade signal without checking funding, open interest, and your liquidation price.
- Mixing venue conventions (coin-margined vs USDT-margined, cross vs isolated) and reading the wrong mark.
- Copying example numbers from a glossary into live size without checking the current book depth and fee schedule.
- Ignoring related terms that change the meaning of the print on a given day.
