Options Hub: see the flow, understand the positioning, build the trade
The Options Hub brings options flow, dealer gamma exposure, an options scanner and a payoff-diagram trade builder together, so you can go from an unusual print to a defined trade without switching tabs.
Options flow: who is trading what, and how aggressively
The flow tab lists single-leg trades and multi-leg trades (spreads and combos) as they print. Each line is tagged so you can tell a routine order from an unusual one.
- Sweeps: one order filled across several exchanges at once, which usually means the buyer wanted the fill quickly.
- Whale alerts: very large single orders.
- 0-DTE: contracts that expire the same trading day.
- Unusual activity, high implied volatility and out-of-the-money spikes as separate filters, plus calls only or puts only, bullish or bearish, and a minimum premium from $25K upward.
Gamma exposure (GEX): where dealers may pin or accelerate price
Enter a ticker and, if you like, a single expiry. The GEX view shows total net gamma exposure, an approximate gamma flip level, the current regime, and the call wall and put wall. A strike-by-strike table splits call GEX, put GEX and net GEX.
Where net gamma is positive, dealer hedging tends to pin price near large strikes. Where it is negative, hedging can accelerate moves. It is a map of positioning, not a forecast.
Options scanner: find setups by volatility and flow
Scan for high IV rank, call-heavy, put-heavy or balanced-flow setups, and narrow the list by sector and market cap. Each row shows price, IV rank, implied volatility, volume to open interest, put/call ratio, max pain and a signal.
Trade builder: see the payoff before you commit
Type a ticker to pull a live quote and its option chain, pick a strategy, then click contracts to fill each leg (or let the builder auto-select strikes).
- Strategies: long call, long put, covered call, cash-secured put, bull call spread, bear put spread, straddle and iron condor.
- Payoff diagram as a graph or a table, with a date slider and an implied-volatility slider, so you can see how the position changes before expiry.
- The numbers: max profit, max loss, breakeven, net debit or credit, days to expiry, probability of profit, the Greeks (delta, gamma, theta, vega, rho), IV percentile and expected move.
- Short-dated contracts: same-day and next-day expiries are priced from the hours left until the 4:00 PM ET close.
- Plan notes: write your thesis, invalidation, target and risk notes, then save the setup to your Trade Journal or share it as a card. A heuristic PDB Setup Score summarises the setup.
- Price alerts on a contract are checked in your browser while the tab is open. They are not push alerts.
Put/call ratio and volatility context
A dedicated tab shows the market put/call ratio, the put/call ratio for the scanned universe, VIX, VIX9D and VIX3M with the term structure, and put/call ratio by ticker.
An Options Academy inside the tool
The Options Hub includes a built-in guide to the Greeks, common strategies, IV crush and how to read flow, so the vocabulary is explained right next to the data.

Questions
What is options flow?
Options flow is the stream of options trades as they are reported, with size, strike, expiry and whether the buyer paid the ask or hit the bid. Traders watch it for unusually large or aggressive orders. Flow shows what traded, not why: a large order can be a hedge rather than a directional bet.
What is gamma exposure (GEX)?
GEX estimates how much stock market makers must buy or sell to stay hedged as price moves. Where net gamma is positive, that hedging tends to dampen moves. Where it is negative, it can amplify them. Strikes with large gamma are often called walls.
What is an options sweep?
A sweep is a single order split across several exchanges and filled at the same time. It usually signals that the buyer wanted the fill quickly rather than waiting for a better price.
Can the trade builder price a 0DTE option?
Yes. Same-day and next-day expiries are priced using the hours left until the 4:00 PM ET close, and the price-range control goes down to fractions of a percent for these short-dated contracts.
Does the Options Hub tell me what to trade?
No. It shows flow, positioning and payoff maths so you can form your own view. Sentiment labels are an inference from how premium was traded, not a prediction.
Which plan includes the Options Hub?
The Options Hub is included with the Gold plan. See the pricing page for current plans and prices.
