Why Your Brain Sabotages Your Stop-Loss
You know you shouldn't move the stop. You do it anyway. That's not a willpower problem. That's neurology: proven by a Nobel laureate.
The Discovery That Explains Everything
In 1979, Kahneman and Tversky published the Prospect Theory. In 2002, Kahneman received the Nobel Prize. Losses feel roughly twice as painful as equivalent gains feel good. This asymmetry influences every decision in the market.
What Prospect Theory Triggers in Trading
Prospect Theory explains three of the most common trading mistakes: Moving stop-losses, taking profits too early, and revenge trading. In the loss zone, you become risk-seeking; in the profit zone, risk-averse: exactly the opposite of what's optimal.

Terrance Odean documented the Disposition Effect in 1998. A trader who recognizes this pattern makes decisions more consciously. No better analysis needed: just better behavioral control.
A Known Behavioral Pattern
Terrance Odean documented the Disposition Effect in 1998 using real broker accounts. It's a human behavioral pattern, not a personal quirk.
Why Knowledge Alone Doesn't Help
Even Kahneman said: The knowledge doesn't protect him. Only systems protect against bad decisions. You need a tool that shows you your behavioral patterns.
