Quick calculators built around the R-value framework — size your risk, check your edge against prop-firm rules, and read your trades in R. Free, instant, no account needed.
Position Size Calculator
Account size + risk % + stop distance → exact position size. Stocks, forex & CFD.
Would I Pass? New
Check a run against FTMO, Topstep, Apex & more — target, drawdown, daily loss, consistency.
R-Multiple Calculator New
Entry, stop & exit → your trade's R-multiple and reward-to-risk. The unit your whole journal should speak.
Drawdown Recovery
The gain needed to recover any drawdown — losses and recoveries aren't symmetric.
Kelly Criterion
Win rate + reward:risk → full, half & quarter-Kelly position size.
Expectancy
Win rate + avg win/loss → expected profit per trade, in $ and in R.
Pip Value
What one pip is worth on your forex position, with lot-size presets.
Prop Firm Payout
Profit + split → your take-home vs the firm's cut (FTMO, Topstep, Apex…).
These run on numbers you type. SignalDeck runs them on your real trades.
