Risk education

Risk first. Everything else second.

Accept the risk before you click: decide where you are wrong and how much you can lose before deciding what to trade. All calculators run in your browser; nothing is stored.

Position size calculator

Size = (equity × risk %) ÷ loss per unit at the stop. Why this works.

Leverage changes the margin you post, not the loss at your stop. Fees are counted on entry and on the exit at your stop. Slippage and gaps can make the real loss larger than planned.

Assumes full wins at target and full −1R losses. Real results include partial exits, fees, slippage, and gaps past the stop. The win rate is your input, not a measured edge.

Drawdown recovery table

Losses and gains are not symmetric. The gain needed to recover is loss ÷ (1 − loss).

Writing your risk rules

Write your own rules before you trade. These questions are a starting point.

Questions every rule set should answer

  • What percent of equity can one trade lose?
  • What daily or weekly loss ends trading for that period?
  • How much total risk can be open at once?
  • When does size get cut, and when does it come back?
  • What is never allowed (no stop, averaging down losers, revenge trades)?

Losing streaks at different risk sizes

Math illustration, not performance: the share of an account left after consecutive full losses, ignoring fees, slippage, and gaps.
