About this app

Gross winnings divided by gross losses, which is the least flattering summary of a trading record. Reads the closed trades in your Trader Journal directly — it declares the journal capability and asks your permission the first time. Signed out it runs the same arithmetic on a deliberately mediocre sample book so you can see what it does before granting anything.

Win rates and risk grades are computed by Masterboard from tracked trade outcomes after the strategy is assessed — not self-reported by sellers. Past performance does not guarantee future results.
