My first big lesson: The allure of 'just one more'

Thought I'd drop in here with a quick intro and a confession, given the room. Been trading for a few years, mostly options on US equities, but dabble in $EURUSD when the setup looks ripe. My biggest and earliest lesson? The siren call of 'just one more trade' after a good run. I'd hit my daily profit target, feel like a king, then think, surely the market owes me another. That often led to giving back half, sometimes all, of the day's gains, purely out of overconfidence and a lack of discipline to simply walk away. It's a humbling experience to watch a green day turn amber, or worse, red, all because I couldn't resist chasing the dragon. Now, I have a hard stop-loss and a hard profit-take for the day, and I enforce it with an iron fist, even if it feels like leaving money on the table. Better to lock in the win than try to hit a grand slam every single time.
