Position-size and risk calculator for trading agents
Position-size and risk calculator for trading agents: from account size, risk % per trade, entry and stop (optional target and leverage) get the position size, notional, money at risk, reward-to-risk ratio, break-even win rate and an estimated liquidation price. Pure arithmetic, not financial advice.
