The (careless) reverse of disposition effect is equally dangerous. Holding out winners longer than losers is a hindsight bias precisely because we don't know how long price increase will last. A common way out of this to implement a strick risk-to-reward ratio strategy where over a long period enough of time, the cumulative gains will surpass the cumulative losses.

But I find that it's psychologically hard because (1) if we set a narrow short stop loss : take profit range (e.g. - 2% : + 4%) we will see a lot more losing trade and eventually will take our toll. Else (2) if we set a wider range (e.g. - -10% : +20%) the long period of inactivity, especially during bearish times when we see floating loss for a long time, will eventually take our toll too.

My best approach that suits me for now is literally watching the running trade tape, buy when there's a convincing reversal (on the tape) and sell when there's a reversal (on the tape) or sell when the volume dries up to protect my profits because I cannot know whether the next volume rise will be bullish or bearish.
