Understand the true cost of trading losses
| Drawdown | Gain Needed | Difficulty |
|---|
One of the most important concepts in trading is that losses and gains are not symmetrical. A 50% loss does not require a 50% gain to recover — it requires a 100% gain. This exponential relationship means that protecting capital is always more important than chasing profits.
The formula is: Required Gain % = Loss% / (100 - Loss%) × 100
Professional traders typically aim to keep maximum drawdown below 20%, because beyond that threshold, recovery becomes increasingly difficult. At 30% drawdown, you need 42.86% to break even. At 50%, you need to double your account just to get back to where you started.
This is why most professional traders risk only 1-2% per trade. Even a streak of 10 consecutive losses at 1% risk results in only a ~9.6% drawdown, which requires just a ~10.6% gain to recover — very achievable with a solid strategy.
