What Is Thesis?
A trade thesis is the specific reasoning behind why you're entering a trade — what you expect to happen, why, and within what timeframe. A complete thesis includes: the setup (what pattern or signal triggered the idea), the catalyst (what will drive the move), the target (where you expect price to go), the timeframe (how long you expect it to take), and the invalidation (what would prove you wrong).
How Thesis Works
Well-constructed theses are testable and falsifiable. "BTC will go up" is not a thesis. "BTC will break $50,000 within 2 weeks because exchange reserves are at a 5-year low, funding rates are neutral, and the 200-day MA is providing support — invalidated if daily close below $44,000" is a thesis. The specificity allows objective evaluation of whether the thesis is playing out or failing.
Why It Matters for Traders
Writing down your thesis for every trade is the single best practice for improving as a trader. When the thesis is explicit, you can: objectively evaluate when it's invalidated (and exit), review past theses to identify patterns in your thinking, and avoid the psychological trap of changing your thesis mid-trade to justify holding a losing position. A trade journal organized around theses accelerates the learning cycle exponentially.
How Perps Traders Use This
For CEX perpetual futures, treat thesis 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 thesis 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.
