I built a simple position size calculator to stop myself from negotiating risk mid-trade
One thing I noticed in my own trading is that position sizing becomes very "negotiable" once a setup looks really good.
You start thinking: "2% risk is too small… this setup is A+, I’ll size up."
So I built a small web-based calculator to make the risk number fixed before entering a trade.
It calculates:
• lot size based on account balance
• risk %
• stop loss distance
• spread adjustment
• risk/reward
• supports forex, gold and crypto pairs
Some traders already suggested interesting improvements like margin/leverage checks and session risk tracking.
Curious what features active traders would want in a tool like this.
