Who this is for — Anyone who uses historical statistics and wants to avoid applying rules that worked yesterday to a market that behaves differently today.
A regime shift is a substantial change in market behaviour: volatility, correlations, directionality, or event response evolve and make past results less reliable. Recognising it early protects capital and confidence in the process.
In plain terms — The method is not necessarily "broken": context may have changed. Before forcing trading, you need to realign the rules.
Prerequisites — Complete silver-path first (min.: context, market-conditions, scenario, no-trade-conditions). Foundation: bronze-path.
Operational signals to monitor
Regime change is not identified by a single candle, but by a coherent set of signals.
- Persistent drop in setup quality versus the normal sample.
- Increase in anomalous stops due to different microstructure.
- Divergence between expected and realised performance.
Example — A breakout strategy that worked in a trending phase starts collecting false signals for three weeks in a noisy range. Instead of increasing frequency, you run an audit, reduce size, and suspend the worst variants until context is coherent again.
Common mistakes to avoid
- Denying regime change to defend ego.
- Changing the entire method after a few losing trades.
- Keeping the same exposure while edge is declining.
Card
- What it is: structural transition in market behaviour.
- What changes: reliability of recent statistics drops unless adapted.
- Quick check: compare current metrics with plan baseline.
