Trading Risk Calculators

Translate a defined loss limit into a position or stop price. These tools show the formula, assumptions, and limitations behind every result.

A practical workflow

Start with the risk you can define.

  1. Define where the trade idea is invalid.
  2. Calculate the stop price.
  3. Size the position from your maximum planned loss.
  4. Review the assumptions before placing a trade.

Risk is an input, not a promise.
