TradingCalc
Free trading calculators and an MCP server that return exact numbers
TradingCalc offers a free set of deterministic trading calculators. For options, it includes Black-Scholes price and Greeks, payoff and breakeven, and implied volatility. For forex, it calculates position size, pip value, margin, swap, and correlation. Risk tools cover Sharpe ratio, VaR, and a portfolio tearsheet. For crypto perpetual futures, it provides PnL, liquidation price, breakeven, and funding cost across many exchanges, including coin-margined contracts.
The same tools are available over MCP and REST for AI agents and trading bots. The core calculators are verified against public test vectors on a live page.
