Drawdown Management and Capital Protection

Drawdown is the decline from an account's peak balance to its lowest point afterward, usually expressed as a percentage. Every trader experiences drawdowns -- they're a normal part of any strategy that isn't right 100% of the time -- but the size and handling of a drawdown determines whether it's a manageable setback or the end of an account. A 20% drawdown needs a 25% gain just to recover; a 50% drawdown needs a 100% gain, which is why avoiding deep drawdowns matters far more than it first appears.

The first line of defense is the risk-per-trade rules covered earlier in this module: risking 1-2% per trade means a losing streak of ten trades in a row costs roughly 10-20% of the account, not 50% or more. The second line of defense is a drawdown limit -- a rule that says "if the account falls X% from its peak, stop trading and reassess" rather than continuing to trade the same way through a losing streak in the hope it turns around on its own.

Reassessing doesn't necessarily mean the strategy is broken -- losing streaks happen even to strategies with a genuine statistical edge, simply due to variance. What it does mean is stepping back to check: has anything about market conditions changed, is the strategy being followed correctly, and is the position sizing still appropriate for the account's current (smaller) balance. Continuing to risk the same dollar amount per trade after a drawdown, rather than recalculating position size against the new, lower balance, is one of the more common ways a bad stretch turns into an account-ending one.

Capital protection, ultimately, is the mindset behind all of this: treating the account balance itself as the asset to be protected first, with profit as something that follows from consistently not blowing up, rather than something to chase by increasing risk after losses to "win it back" faster.
