Loss aversion, explained with the only example traders need

Research consistently shows losses hurt roughly twice as much as equivalent gains feel good. In trading this manifests precisely: you cut winners fast (locking the good feeling) and hold losers long (avoiding the bad one) - the exact inverse of profitable behavior. The countermeasure isn’t feeling less; it’s pre-commitment: hard stops and targets set BEFORE entry, when you’re a strategist, not during, when you’re a defendant. Bias can’t be deleted. It can be outvoted by rules written earlier.
