Hi all. I found this page after a rough trading week when my risk control clearly wasn t working anymore. While browsing a discussion thread about common mistakes, someone mentioned a simple calculator and linked to https://trading.biz/position-size-calculator right in the middle of their explanation. What interested me was how quickly it showed whether my position sizes made sense or not. I realized I d been risking too much without noticing. After adjusting my approach and sticking to clearer limits, my next trades felt calmer. One decent win covered recent losses, and I logged out feeling more confident instead of stressed.
