Stop Loss Invalidation
Stop loss invalidation is the technical concept where a price level is identified as the point at which the original trade thesis is proven wrong. If the market reaches this level, the reason for entering the trade no longer exists, and the position must be closed.
This is different from a random exit point; it is a fundamental part of the trade setup. For example, if a trade is based on a support level, the stop loss would be placed just below that level.
If the price breaks below, the support is invalidated, and the trade is no longer valid. This approach ensures that losses are taken only when the market proves the trader's analysis incorrect.
It prevents the common mistake of hoping for a reversal when the premise of the trade has failed. Proper invalidation analysis is critical for maintaining a positive expectancy.
It is the logical basis for every stop loss.
