Quick guide

Which calculator should you use first?

Start with the position size calculator before every trade — it decides how much you can safely buy. Then check risk-reward to confirm the trade is worth taking, and run the brokerage calculator to see your real net P&L after all charges. The other tools answer planning questions.
