A trade I took this week that reminded me why planning matters more than intelligence in this business. I had a perfect EUR/USD setup on Thursday. The analysis was thorough — ICT weekly bias confirmed, FVG at 1.0826–1.0840, HTF bullish structure, kill zone timing. I had everything. Except I didn't write my trade plan down before entering. I had it in my head — which turned out not to be good enough. When price dipped to 1.0830, I second-guessed my stop placement and tightened it to 1.0818 instead of my planned 1.0808. Got stopped out at 1.0818 with a small loss. Price then ran to exactly 1.0880 — my original target. With my original stop at 1.0808, I would have held through the dip and hit the target. The plan was right. My in-the-moment modification (without writing it down, without accountability) was wrong. Lesson I keep re-learning: Write the plan down. Every trade. Entry, stop, target. The act of writing it creates accountability to the plan that "remembering it" never does. Do you write down your trade plans before entering?
