最大回撤
账户从历史最高点跌至之后最低点的最大跌幅，代表策略在最坏情况下的账面损失程度
Timeline (last 90 days)
Quantitative risk metrics (standard deviation, Beta, maximum drawdown, annualized volatility) can only describe historical risk characteristics, cannot predict the future, and do not cover structural risks such as liquidity and concentration.
For automated trading bots, a common practice is to set a maximum drawdown threshold that triggers automatic position reduction or shutdown, and to limit the risk of a single trade to a fixed percentage of account equity (such as 1%-2%).
Maximum drawdown measures the largest decline from a historical peak to a trough, directly reflecting the worst-case shrinkage of capital; a strategy with a 50% maximum drawdown requires a 100% gain to break even.
Maximum Drawdown describes the maximum loss magnitude of a strategy from peak to trough within a specific time window.
Evaluating backtested returns requires attention to risk-adjusted metrics such as the Sharpe ratio and maximum drawdown; a strategy with 30% annualized returns but a 60% maximum drawdown is inferior to one with 15% annualized returns but only a 10% drawdown.
