Core surfaces
Markets overview
The home page after signing in. Shows the day's biggest moves: total options volume, put-call ratio, count of unusual flow events, top 20 most-active tickers, top unusual flow trades. Use it for a quick scan of where the market's attention is today.
Tickers
Leaderboard of all 100 covered tickers sorted by absolute dealer gamma exposure. Sort by spot price, total GEX, call GEX, put GEX, flip level, max pain, or expected daily move. Filter by free tier only.
Per-ticker page
Deep dive on one symbol. Shows the GEX summary block (total exposure, flip strike, max pain, expected move), a chart of GEX by strike, the latest fundamentals, recent unusual flow on that ticker, and the full options chain with all greeks.
Flow feed
Cross-universe unusual options flow. Filterable by minimum premium, direction (bullish, bearish, neutral), and ticker. Useful for following "smart money" or spotting positioning trends.
Specialized analytics
Sector gamma rotation
Total GEX summed by sector. Tells you which sectors are in a volatility-dampening regime versus volatility-amplifying.
Gamma storm alerts
Flags large snapshot-to-snapshot changes in dealer gamma exposure. Helps spot positioning shifts that may precede big moves.
Vol arb (IV vs realized vol)
Compares what the market expects (implied volatility from option prices) versus what actually happened (realized volatility from past prices). When IV is much higher than RV, options are expensive. When IV is below RV, options are cheap.
Skew
Compares put IV to call IV at equivalent distances from the money. Positive skew means puts cost more (downside hedging demand). Extremes can signal market regime shifts.
IV term structure
Implied vol by expiration. Tells you whether the market expects bigger moves near-term or far-term. Backwardation (near-term higher) often signals event risk.
Seasonality
Average weekly return by week of year for any ticker. Highlights statistically strong or weak weeks across history.
Greeks heatmap
2D color map of strikes versus expirations with cell color representing the chosen greek or open interest. Visual way to spot where gamma is concentrated.
Correlation matrix
Pairwise correlation of daily returns across a set of tickers. Useful for pairs trading or building uncorrelated baskets.
Tools (interactive)
Strike picker
Tell it the ticker, direction (call or put), target delta, and target days to expiration. It returns the 15 best contracts matching, ranked by closeness to your inputs and weighted against illiquid contracts.
Strategy builder
Pick a strategy template (bull call spread, bear put spread, long straddle, long strangle, iron condor, covered call, cash-secured put). It auto-fills the legs from the current chain near spot and plots the payoff curve at expiration.
Position x-ray
Enter the legs of any position you hold or are considering. See the payoff curve, breakeven prices, max profit, max loss. Works for single options, spreads, complex multi-leg structures.
Trade grader
Submit a hypothetical trade. It scores from A to F across liquidity, bid-ask spread, IV percentile, delta sanity, and days to expiration. Tells you specifically what's good or bad about the trade.
Backtest engine
Pick a ticker, pick a basic stock strategy (moving average crossover, RSI oversold, 52-week breakout, mean reversion), and pick a date range. See how the strategy would have performed versus buy-and-hold over the past 5 years.
