One bad trade becomes two. Two becomes a blown account. The revenge trade is the most dangerous pattern in trading β and the hardest to see when you're in it.
A revenge trade is any trade taken primarily to recover losses from a previous trade β driven by emotion rather than analysis. The setup may look valid on the surface, but the intent is emotional: to prove yourself right, to win back what was taken.
The market didn't take your money. Your reaction to the market did.
