Position Sizing: How Much Should You Actually Risk Per Trade?
Traders obsess over entries. But the skill that actually decides whether you survive long enough to get good isn't where you enter — it's how much you put on. Position sizing is the quiet discipline that keeps a losing streak from becoming a closed account.
Here's the uncomfortable truth: you can have a winning strategy and still blow up if you size wrong. A great edge run with reckless size dies on the first bad streak. A modest edge run with disciplined size compounds for years. Position sizing is not a detail — it's the foundation everything else stands on.
The 1% rule: your survival setting
The core principle most professionals follow: risk only a small, fixed percentage of your account on any single trade — commonly 1%, sometimes up to 2% for the more aggressive. On a $10,000 account, 1% means you lose no more than $100 if the trade hits your stop. Not 1% of the position — 1% of your account.
Why so small? Because it makes any single loss survivable and emotionally quiet. When one trade can only cost 1%, you don't panic, you don't move your stop, and you don't revenge-trade. Small risk isn't just math — it's what keeps your psychology intact.
Size from the stop, not from the vibe
This is the part beginners get backwards. They pick a position size based on how confident they feel or how much they want to make, then set a stop wherever. Do it the other way around. Your position size is a calculation, and it flows from three numbers:
- Your account size — say $10,000.
- Your risk per trade — 1% = $100.
- Your stop distance — how far, in price, from entry to stop.
The formula: Position size = Risk amount ÷ Stop distance. If your stop is 2% away from entry, then $100 of risk supports a $5,000 position ($100 ÷ 0.02). If your stop is only 1% away, the same $100 supports a $10,000 position. The tighter your stop, the larger the position you can hold for the same dollar risk — and vice versa.
Your risk is fixed (1% of account). Your stop distance varies by trade. So your position size changes every trade to keep the dollar risk constant. A wide stop = smaller position. A tight stop = bigger position. Same risk either way.
Why this quietly wins
Fixing your risk per trade does three powerful things at once. It caps your downside so no single trade can seriously hurt you. It removes emotion from sizing — the number is calculated, not felt. And it survives losing streaks, which are a mathematical certainty even with a good strategy. Ten losses in a row at 1% leaves you down about 10%; the same streak at 10% risk leaves you nearly wiped out and trading scared.
Notice how this connects to the stop-loss rule: sizing off your stop only works if the stop actually holds. Move the stop, and you've silently blown past your 1% risk — which is exactly why never widening your stop and disciplined sizing are two halves of the same habit.
Key takeaways
- Position sizing, not entries, is what keeps you in the game long-term.
- Risk a small fixed % of your account per trade (commonly 1%) — of the account, not the position.
- Size = risk amount ÷ stop distance. Tighter stop = bigger position for the same risk.
- Fixed risk caps losses, removes emotion, and survives the inevitable losing streak.
