The urge to size up after three wins
Three winning scalps in a row feel like a message. The market is cooperating. The system is working. Time to increase size.
The brain treats a streak as evidence, even though each trade is a separate event with its own odds. In a strategy with a 55 percent win rate, three wins in a row occurs about one time in six. It is nothing special.
The impulse is strongest on short timeframes, because the feedback comes so quickly. Within ten minutes, a trader can go from calm to euphoric.
What tends to follow is a larger position taken at a moment of unjustified confidence, then a normal loss that now hurts three times as much. The emotional swing from that loss often leads to another bad decision.
Some traders protect themselves by fixing position size in advance, with no exceptions, no matter the recent results.
Has a winning streak ever led to a bigger position that wiped out the gains?
