The siren song of 'just one more trade'

It's easy to get caught up in the momentum, especially on a green day. My biggest recurring mistake, one that still bites me occasionally, is overtrading after a decent win streak. You feel invincible, like you've unlocked some cheat code, and suddenly every setup looks perfect. The discipline that led to those initial wins goes right out the window.

I remember one afternoon last year, had three solid trades on some tech names early, locked in decent profit. Instead of calling it a day, I started digging for more. Ended up forcing a trade on a breakout that had already extended too far, didn't respect my own risk parameters, and watched my gains evaporate in about 20 minutes. It's not just the money lost, it's the mental fatigue and the frustration of giving back what I'd worked for. Now, I try to implement a hard stop after a certain number of wins or a certain profit target. Easier said than done when the market is buzzing, but it's crucial for capital preservation.
