Strategy Drift

Strategy drift occurs when a trader slowly deviates from their original, tested trading plan, often due to market pressure, overconfidence, or a desire to chase new opportunities. This drift can be subtle, starting with minor changes in position sizing or the addition of new, unproven indicators, but over time, it can fundamentally alter the nature of the strategy.

When a strategy drifts, the trader is no longer executing the plan that they backtested and validated, which makes it impossible to maintain consistent performance. Strategy drift is often a symptom of a lack of discipline or a failure to trust one's own process.

To prevent this, professional traders conduct regular audits of their trading activity to ensure that their actions remain aligned with their established rules. If a change is needed, it should be done through a formal, documented process that involves testing and evaluation, not through impulsive adjustments made during live trading.

By staying true to the core tenets of their strategy, traders can avoid the pitfalls of drift and maintain a clear, disciplined path toward their long-term financial goals.
