Overconfidence
The feeling after a winning streak that you can't miss. The prelude to account-altering losses.
Winning streaks feel like skill. Usually they're a combination of skill + variance + regime alignment. The size-up that follows a streak is where gains get given back with interest. The cure: fixed-% risk, ignore the last 10 trades.
