Why market regimes matter
A trading strategy can produce different trigger counts and outcomes as volatility, trend, and liquidity change. An overall average can hide that dependence.
Group a backtest by the conditions that matter to the rule. Record the number of independent triggers, the outcome range, and any data gaps in each group. If the strategy is meant for one regime, state that scope before live monitoring.
Common regime labels
Useful labels describe observable conditions: rising or falling prices, high or low volatility, and deep or thin liquidity. Define each label with fixed measurements so another person can reproduce the grouping.
