Position sizing

Size is the lever that holds risk constant

Once you've fixed how much you're willing to risk per trade and where your stop is, position size is no longer a guess — it's arithmetic. Size is the dial you turn so that every trade risks the same fixed amount, whether the stop is tight or wide. This is what keeps a wide-stop trade from quietly being five times riskier than a tight-stop one.

The relationship

The logic, in plain terms: the smaller fraction of your account you risk, and the wider your stop, the smaller the position. Specifically — your fixed dollar risk divided by the per-share distance to your stop gives the number of shares. The same fixed risk with a wider stop simply means fewer shares; with a tighter stop, more.

• Wide stop → smaller position. Volatile names and far stops get fewer shares, not more risk.
• Tight stop → larger position. A clean setup with a close invalidation can carry more shares at the same dollar risk.
• Risk stays constant. That's the whole point — the dollar amount at stake is identical across trades.

Sizing and the cycle method

Cycle trading produces a natural spread of stop distances — a tight reclaim here, a wide structural stop there. Position sizing is what lets you take them all on equal footing. It also lets confluence inform conviction sensibly: some traders risk slightly more on their highest-confluence, deepest-sample setups and slightly less on thinner ones — always within sane bounds, never abandoning the fixed-fraction principle.

Sizing is mechanical once risk is defined — but the discipline to actually use it, every time, is psychological. The remaining lessons are about that: letting bad trades go, journaling, and staying out of your own way. As always, this is educational; your specific sizing depends on your circumstances and is worth reviewing with a licensed professional.
