Market Regime
A market regime is the prevailing behavioural state of a market — trending or ranging, calm or volatile, risk-seeking or risk-averse. The same strategy can perform completely differently across regimes, which is why serious traders ask not only "is this signal good?" but "in which regime was it measured, and which regime are we in now?"
Why do strategies fail when the regime shifts?
Every strategy embeds assumptions about how the market behaves: breakout strategies assume moves continue, mean-reversion strategies assume they snap back, volatility settings assume a typical range of movement. A regime shift silently invalidates those assumptions — breakouts that ran for days in a trending market start failing in a chop; stops calibrated to quiet conditions get wicked out constantly when volatility doubles. The strategy's rules did not change; the world they were fitted to did. This is also the classic backtesting trap: parameters tuned on one regime's data look excellent until the regime ends.
How do you detect a market regime change?
There is no bell that rings. Practitioners watch measurable proxies: realized volatility rising or collapsing relative to its recent range, trend-strength measures flipping, breadth (how many assets participate in moves) narrowing or widening, correlations tightening in stress. In crypto, one regime fact is well-documented: in broad risk-off phases, correlations across coins rise sharply and most altcoins follow Bitcoin regardless of their own story — reducing the diversification an altcoin portfolio appears to offer. Detection always lags reality; robust practice assumes regime classification is probabilistic and sizes risk so that being wrong for a while is survivable.
