🎯 Calculate your trade size right now
Enter your account balance and stop loss distance to compute exact contract size.
1. The Math of Drawdown Asymmetry
Most novice traders underestimate the non-linear relationship between percentage loss and the subsequent return required to break even:
| Account Loss | Gain Required to Break Even | Difficulty Rating |
|---|---|---|
| -10% | +11.1% | Routine trade recovery |
| -25% | +33.3% | Moderate effort |
| -50% | +100.0% | Doubling required |
| -75% | +300.0% | Extreme risk of ruin |
Because a 50% loss requires a 100% gain simply to return to zero, capital preservation must always supersede profit maximization.
2. The Universal Position Sizing Equation
Rather than picking arbitrary position sizes based on excitement, disciplined traders let their stop loss distance dictate their total trade exposure:
1. Risk Capital ($) = Account Balance × Risk Tolerance % (e.g. 1%)
2. Price Risk % = | Entry Price − Stop Loss Price | ÷ Entry Price
3. Position Size ($) = Risk Capital ($) ÷ Price Risk %
Following this rule guarantees that whether your stop loss is 2% away or 15% away, hitting the invalidation level costs you exactly the pre-planned 1% of your total account.
