User Guide
A walkthrough of every tab, in the order you'll actually use them — from setting a price to closing a position and seeing it land in your trade record.
Every price the app uses — in the Pricer, Risk, and Watchlist tabs — comes from here. Set it once, live or manually, and it's everywhere.
Used by every option pricing calculation across the app. Adjust it at the top of Market if you want a different assumption than the default.
Type a symbol and a price under "Set Price," or leave the price blank and tap "Fetch Live Price" for a current quote. Either way, it's saved and reused everywhere that ticker appears.
Pull down to refresh, tap the refresh icon on one ticker, or use "Refresh All" to update every tracked symbol at once.
SPY shown here only because it's held in an open Portfolio position
Track tickers you don't hold yet, with price alerts and a quick read on momentum.
Tap +, enter a ticker, and optionally set a High and Low alert level. Both must sit on the correct side of the current price — a High Alert below today's price would fire immediately instead of warning you of something ahead, so it's not allowed.
Tap any row to see RSI, realized volatility, return skew, and recent price history.
Change High or Low from the detail view. Save commits the change; Cancel discards it and leaves the original alert untouched.
Model a strategy before you put it on — thirteen structures, priced with Black-Scholes, with a live P&L chart.
Single, Vertical Spread, Straddle, Strangle, Calendar, Diagonal, Butterfly, Iron Butterfly, Condor, Iron Condor, Risk Reversal, Ratio Spread, Broken Wing Butterfly.
Ticker, spot, strike, volatility, days to expiry — or fetch a live spot price for the ticker you've entered.
Drag the Evaluation Date slider to see how time decay reshapes the curve as expiration approaches — it's a mark-to-market view, not just the payoff at expiry.
Toggle "Hedge with Stock," pick long or short, and enter any share count — full or partial. This only affects the chart here; it's never included when you book. To actually hold the shares, book them separately as a Stock trade in Risk.
Enter the actual net premium you were filled at. The model's theoretical price and your real fill are tracked as two separate numbers — never blended into one leg's price — so every leg you see later still looks like a real, individual quote.
Every open position, its aggregate risk, and one place to close out.
Each position shows its present value and change from initial value, collapsed by default. Tap a row to expand it for the full per-leg breakdown, net premium, and estimated margin.
Net delta, vega, and theta across your whole book, an estimated total margin, and a stress test slider showing how the portfolio would move on a parallel market shock from −30% to +30%.
Swipe a row and tap Close. Enter your exit price and watch the realized P&L update live before you commit — tapping "Close Trade" logs it to Trade Record immediately, no separate confirmation step.
Your closed-trade history — every position that's ever been closed in Risk, automatically.
Every record here comes from closing a position in Risk. There's no separate way to log a trade from this tab — that's by design, so your record always matches what actually happened.
Each leg shows entry price next to exit price on one line, with any fill adjustment — the gap between the model price and what you actually got filled at — shown separately at the top and bottom, so no individual leg's price ever looks distorted.
Swipe to highlight a trade you want to flag, email a full report of your trade history, or reset all records if you're starting fresh.
RiskAlgo is a calculator and portfolio tracker, built for active options traders and finance students who want to model strategies and keep a clean record of what they've done. It is not a licensed investment adviser, and nothing in the app — pricing, Greeks, margin estimates, or stress test figures — is personalized financial or legal advice.
Margin figures are Reg-T-style estimates for stock and options only; they are not your broker's actual requirement, and futures margin isn't modeled at all yet. The stress test assumes every position's underlying moves by the same percentage, with volatility and time to expiry held fixed — a simplification, not a forecast. Confirm real figures in your broker's own platform before making any decision.
RiskAlgo is currently in development and not yet available on the App Store.
