Risk Management & Position Sizing
No edge survives without risk control. Learn the non-negotiables: risk per trade, position sizing, and the math of survival.
Risk per trade
Risk a fixed, small percentage of your account on each trade — 0.5% to 1% for beginners. This means if your stop is hit, you lose at most that fraction of your account. With 1% risk, you can lose 20 trades in a row and still have over 80% of your capital — survivable.
Risking 5% or more per trade is how accounts blow up. A string of losses is statistically normal; oversized risk turns a normal drawdown into a disaster.
Position sizing
Position size = (Account × Risk %) / (Entry − Stop distance). If your account is $10,000 and you risk 1% ($100), and your entry-to-stop distance is 50 pips, you size so that 50 pips = $100. The stop distance determines the size, not the other way around.
Never adjust your stop to fit a larger position. The stop goes where the setup is invalidated (beyond the sweep), and the size adjusts to keep risk constant.
Reward and expectancy
Aim for a minimum reward-to-risk of 2:1 — your target should be at least twice your risk. With SMC, targeting the next liquidity pool often gives 2:1 or better naturally. Over many trades, your edge = (win rate × average win) − (loss rate × average loss). Protect the downside; the upside takes care of itself.
Sizing a real trade, step by step
Your account is $10,000. You're risking 1% per trade. Your EURUSD setup: entry 1.1050, stop 1.1000 — a 50-pip stop distance.
- 1Dollar risk first: $10,000 × 1% = $100. This is the most you can lose — decided before the trade, never during it.
- 2Stop distance: 1.1050 − 1.1000 = 0.0050 (50 pips). The setup sets the stop; you never move the stop to fit a bigger size.
- 3Position size = dollar risk ÷ stop distance = $100 ÷ 0.0050 = 20,000 units. That position loses exactly $100 if the stop is hit.
- 4Check the reward: your target at 1.1120 is 70 pips away — $140 of reward against $100 of risk. That's below the 2:1 minimum, so the disciplined move is to pass or wait for a tighter entry.
The stop distance determines the size — never the other way around. Risk is chosen at your desk, not on the chart.
