First post — big lesson from sizing up too fast

Hey everyone, new here to Traderforum. Been trading equities and FX for about 4 years now. My biggest lesson, learned the hard way last year, was scaling up position size too quickly after a decent winning streak. I let ego creep in after a few good calls on $NVDA and $TSLA, then doubled down on a less conviction trade which went south fast, essentially giving back a quarter of the year's gains in one go. It taught me the importance of sticking to a consistent risk percentage, regardless of recent performance.
