Challenge planner
With my edge and this firm's rules, how often does it pass, is the fee worth it, and how big can one trade be?
How it works
Three calculators as one flow. Your edge and the firm's rules give a simulated pass rate; the pass rate and the deal give an expected value; the rules and your stop give the largest safe size. The simulation is the same seeded model as the pass probability calculator, so equal inputs give equal answers on every device.

Questions
Where are my scenarios kept?
In this browser, on this device. Clearing the site's data removes them, and they do not follow you to another device.
Can I compare two firms' deals?
Yes: save a scenario per firm and the table below the planner puts them side by side.
