// 8 ANALYTICS CALCULATORS
Co-developed with two former Goldman prop-desk quants.
Co-developed with two former Goldman prop-desk quants.
Every pre-trade decision, before the click.
Position-size, risk-reward, Greeks, IV rank, expectancy — the eight calculators that serious traders open before every entry. No rounding tricks, no marketing math, no "max profit" lies. The output is what the math says, formatted for the screen you actually trade on.
IV Ranker
52-week IV percentile, term-structure slope, and put-call skew in a single panel. Spot cheap premium before earnings and front-month vol crush setups.
Position-Size
Fixed-fractional, fixed-dollar, Kelly-fraction, and volatility-targeted sizing — with a hard cap on per-trade and per-day loss baked in.
Risk-Reward
Entry, stop, target, trailing-stop, partial-exit tiers — output as R-multiples with breakeven, expectancy, and max drawdown at the trade and portfolio level.
Kelly Criterion
Full-Kelly, half-Kelly and quarter-Kelly output from your measured win-rate and payoff. Includes a "ruin probability" line so you never over-size on a hot streak.
Expectancy
Long-run expectancy per trade in R and in currency, plus a confidence interval from your sample size. Tells you whether a strategy is worth scaling before you scale it.
Correlation Matrix
Rolling 30/60/90-day correlation between any two instruments in your watchlist. Includes beta-adjusted exposure so you can size a hedge without over-thinking the math.
Drawdown Tracker
Running peak-to-trough drawdown with daily, weekly and monthly slices. Pair with the Risk Dashboard to catch over-leverage before the broker does.

// MODULE 03 · GREEKS ENGINE
Options Greeks Engine
A standalone module dedicated to options math — because a single Greeks line in a calculator isn't enough when you're running a 30-leg iron condor. Full chain, full Greeks, full payoff.

- Black-Scholes, binomial, and trinomial trees on the same contract
- Per-leg and aggregate Greeks — delta, gamma, theta, vega, rho
