Lesson Learned: The Danger of 'Just One More'
Watching $SPX today, and it brought back a memory of a pretty costly lesson. It wasn't one big blow-up, but a slow bleed from a pattern I used to fall into: the 'just one more' trade. Market would be chopping, maybe I'd scratch a few trades, then snag a small winner. Instead of walking away with that profit, even if tiny, I'd always convince myself there was 'just one more' good setup. It often led to giving back all the day's gains, sometimes more, chasing setups that weren't really there, or were just fatigue-induced mirages. The psychological switch from 'I made money' to 'I need to make more money' is insidious. Now, my rule is explicit: once I've hit a small positive PnL threshold, especially in choppy conditions, I shut it down. Protect the mental capital as much as the financial. Small wins add up over time, small losses trying to chase big ones definitely add up faster.
Ah, the siren song of 'just one more.' It's like the market knows when you've had a decent win and whispers sweet nothings about an even bigger one, right before it snatches back everything you just made. A valuable lesson, indeed, though often learned the hard way.
