Log initial risk and exit for instant R calculation
Mantis captures your entry price, stop-loss, and exit level so every trade automatically converts into R-multiple—no spreadsheet formulas or manual math required.
Your R-multiple tells you how many times your initial risk you made or lost on each trade—turning every outcome into a standardized, comparable unit. By tracking R-multiple in your trading journal, you shift focus from arbitrary dollar amounts to consistent risk-reward execution, making it easier to spot which setups deliver multiples of your risk and which drain your account. A disciplined journal that captures R-multiple for every trade reveals your true edge, highlights behavioral patterns, and shows whether you're executing your plan or chasing random profits.

Frequently asked questions
What exactly is R-multiple?
R-multiple expresses profit or loss as a ratio of your initial risk per trade. If you risked $100 (distance from entry to stop) and made $200, that's +2R. If you lost $50, that's –0.5R. It standardizes results so you can compare every trade on the same scale.
Why track R-multiple instead of just dollar P&L?
Dollar amounts vary with position size and account balance, making it hard to compare a $1,000 win on a large position to a $100 win on a small one. R-multiple shows whether you're consistently capturing multiples of your risk—the true measure of execution quality.
How often should I review my R-multiple history?
Many traders review weekly or after every ten trades to spot trends—like frequent small losses (–1R exits) or rare large wins (+3R or more). Regular review in your journal helps you recognize whether you're following your plan or cutting winners too early.
Can I track R-multiple for partial exits?
Yes. Log each partial exit as a separate line in your journal with its own R calculation, or average the R across all exit tranches. Mantis lets you record multiple exits so you can see the blended R-multiple for complex trade management.
Does Mantis sync my R-multiple data to the cloud?
No. Mantis stores all trade data—including R-multiple, entry, stop, and exit levels—locally on your device only. There is no cloud sync or backup, ensuring your risk metrics and performance history remain completely private.
