Browse the full options chain on stocks, ETFs and futures like ES and NQ: bid/ask premiums, Greeks and implied volatility for every strike and expiry. All you need is a free account: no paid plan, no credit card.
The options chain is the table that lists every option contract quoted on an underlying, organized by expiry and strike: calls on one side, puts on the other. For each contract it shows the essentials you need to evaluate it: bid and ask price, implied volatility and the Greeks (delta, gamma, theta and vega).
It's the starting tool for anyone trading options: from the chain you understand what a contract costs, how wide the bid-ask spread is, how much volatility the market is pricing at each strike, and how the position will react to the underlying's movement, the passage of time and changes in volatility. Reading an options chain well means picking the right strike and expiry before you even think about the strategy.
On Gaudio OTT the options chain is real-time, covers US stocks, ETFs and futures like ES and NQ, and is completely free: no paid plan required, just a free account.
Pick the symbol and the expiry: the chain shows calls and puts side by side for every strike, with real-time bid and ask prices. Strikes sit in the middle, highlighted against the underlying's current price, so you immediately spot at-the-money, in-the-money and out-of-the-money options.
Every contract comes with the Greeks already computed: delta tells you how much the option moves with the underlying (and approximates the probability of expiring in-the-money), theta how much premium it bleeds each day, vega how much it gains or loses if volatility changes, gamma how fast delta itself changes. Next to them, each strike's implied volatility shows where the market prices the most uncertainty.
The chain is the starting point of the workflow: from the same workspace you move on to open interest, volumes and GEX on the same symbol, and once you've found the right contracts you build the strategy in the Strategy Builder with payoff and aggregate Greeks.
Calls and puts side by side for every strike, with real-time bid/ask premiums, Greeks and implied volatility pre-computed. Everything you see here is included in the free account.

Delta, gamma, theta, vega and implied volatility pre-computed for every contract, calls and puts: the full risk picture at a glance.
Bid and ask prices updated in real time, so you evaluate premiums and bid-ask spreads as they actually move, not on delayed data.
The chain covers the entire US market: stocks, ETFs and futures like ES and NQ, with the same depth of data.
Compare delta, premium and distance from the current price across nearby strikes: find the balance between probability of success and reward that fits your view.
The bid-ask spread tells you what you pay to get in and out: comparing it across strikes and expiries keeps you away from contracts that are too expensive to trade.
Implied volatility by strike and expiry shows where the market prices the most risk: useful ahead of earnings, macro events or technical expirations.
Once you've found the contracts in the chain, move to the Strategy Builder to combine the legs and see payoff, breakevens and aggregate Greeks before you trade.
Many free options chains show delayed data and stop at prices: no Greeks, no per-strike implied volatility, or only behind a subscription. Gaudio OTT gives you the real-time chain with Greeks and IV pre-computed for every contract, including futures like ES and NQ, free forever.
