Three numbers worth deciding before the session, not during it. Each page shows the arithmetic, so you can check it by hand. No signup, nothing leaves your browser.
- Futures position sizeContracts and real risk in dollars and in R, from your account, risk and stop. CME tick values for ES, NQ, YM, RTY, CL, GC and their micros.
- Daily loss limit for prop accountsA personal limit under the firm's, with static or trailing drawdown, and how many losing trades fit before it.
- Cost of a failed challengeChallenges, resets and fees added up, then put in R and in days at your own risk per trade.
Numbers fix the size. A rule fixes the habit.
The free diagnostic finds the execution habit that costs you the most, in 90 seconds, with no signup. The app turns it into one rule with a number and a 30-second check after each session.
