Short answer

A string of winning trades can feel like proof that you have "figured out" the market. This feeling is one of the most dangerous moments in a trader's development, because confidence tends to rise faster than actual skill.

Why It Happens

The brain naturally links recent success with competence, even when a streak was partly the result of favorable market conditions or plain luck. As confidence grows, traders often start skipping steps in their process, believing their instincts alone are enough.

Increasing position size sharply after a few wins, before evidence supports it
Abandoning stop-losses because "this trade feels different"
Taking setups outside a tested strategy out of excitement

Keeping It In Check

Treat each trade as an independent event rather than a continuation of a story. Reviewing whether recent wins actually followed your rules, or happened despite skipping them, gives a more honest picture than the win itself. A streak is not evidence of a better strategy unless the process behind it was sound and repeatable.

Guarding against overconfidence does not mean distrusting every win. It means keeping position sizing and rule-following consistent regardless of recent results, since markets can reverse a streak quickly and larger positions taken in overconfidence carry larger potential losses.
