Free Trading Calculators

Check the mechanics before you practice them. These calculators make drawdown, trading costs, sample uncertainty, and futures contract values explicit. Every tool is free, works without an account, and keeps the assumptions visible.

Three focused tools, each with its methodology and limitations.

Built for transparent practice

Inputs and formulas stay visible so you can check the result instead of treating it as a black box.

Exchange specifications link to primary sources, and rule presets carry review dates because published rules can change.

Examples are simulated and educational. No calculator predicts performance or provides investment advice.
