 #### MaxDrawdown
 
-`MaxDrawdown` uses all trades within `lookback_period` in minutes (or in candles when using `lookback_period_candles`) to determine the maximum drawdown. If the drawdown is below `max_allowed_drawdown`, trading will stop for `stop_duration` in minutes (or in candles when using `stop_duration_candles`) after the last trade - assuming that the bot needs some time to let markets recover.
+The `MaxDrawdown` protection evaluates trades that closed within the current `lookback_period` (or `lookback_period_candles`). It supports 2 calculation modes:
+
+- `calculation_mode: "ratios"` (default): Legacy approximation based on cumulative profit ratios.
+- `calculation_mode: "equity"`: Standard peak-to-trough drawdown on the account equity curve, using starting balance and cumulative absolute profit.
+
+With `calculation_mode: "ratios"`, drawdown is derived from cumulative trade profit ratios, not from the account equity curve. This is kept for backward compatibility and can differ from account-level drawdown when position sizing changes over time.
+
+For new setups, `calculation_mode: "equity"` is recommended. Prefer `calculation_mode: "ratios"` only when you intentionally rely on legacy behavior, especially with fixed stake amount configurations where ratio-based behavior is easier to reason about.
+
+If the observed drawdown exceeds `max_allowed_drawdown`, trading will stop for `stop_duration` after the last trade - assuming that the bot needs some time to let markets recover.
 
 The below sample stops trading for 12 candles if max-drawdown is > 20% considering all pairs - with a minimum of `trade_limit` trades - within the last 48 candles. If desired, `lookback_period` and/or `stop_duration` can be used.
