Example 1: The chased breakout
Price breaks a level and runs four points before the trader notices. The planned entry was the retest near the level with a one-point stop, a clean setup. Instead they chase at the top of the four-point run; the only logical stop is now back below the level, five points away. The same idea that offered a tight one-point risk now demands a five-point stop for a smaller remaining target. The trade direction was right; the chased entry made the risk-reward unworkable.
