What revenge trading is
Revenge trading is placing a trade driven by the urge to win back money you just lost, rather than because the trade itself makes sense. After a painful loss, the desire to "get it back" immediately overwhelms judgement, and the next trade is really about the previous one.
It is one of the most destructive patterns in trading, because it turns a single manageable loss into a chain of larger ones. The market does not know or care that you just lost money, and it owes you nothing back.
Why it escalates
Revenge trades tend to be bigger and worse than normal ones. Because the goal is to recover the loss quickly, the trader increases size and lowers standards, taking a setup they would normally skip. When that trade also loses, the hole is deeper and the urge to recover it is even stronger.
This feedback loop is how a bad day becomes a blown account. Each loss raises the emotional stakes, each subsequent trade is more reckless, and the sizing grows just as the decision-making deteriorates. It is a spiral that has ended more trading careers than any bad strategy.
Breaking the spiral
The most reliable defence is a hard rule to stop trading after a loss that exceeds a set limit for the day, and to step away from the screen. Removing yourself physically breaks the loop far better than promising yourself you will "stay disciplined" while staring at the chart.
It also helps to have accepted, before the day starts, that losing days are a normal part of trading and do not need to be recovered immediately. A loss is not an insult to answer; it is a routine cost of doing business. The money will be recovered, if at all, over many future trades — never by forcing it back in a fit of frustration.
