What Option Decode does
Last updated 20 September 2026
Option Decode reads the whole option chain and tells you where writers are defending. It is an analytics terminal, not a broker and not an advisory service — every screen below shows you the working, so you can disagree with it.
Starter — Read the chain and practise.
Free for your first 7 days, then ₹299/month.
- Dashboard
- Whole-chain pressure and bias, with the strongest support and resistance ranked by the writing behind each strike rather than by raw open interest.
- Strike Matrix
- Writer conviction inside one horizon's delta band, shown with its sample size so a reading taken from two strikes is not mistaken for a strong one.
- Option Chain
- Every strike's call and put open interest and its change, with walls flagged even when they sit outside the day's expected range.
- Option Chain Graph
- Open-interest change for one strike, or several added together, charted against spot through the session and refreshed with the chain.
- Back-test
- Place a trade against the live chain with no money at risk; stop and target are tracked for you, tick by tick.
Pro — The full analytics suite.
₹1,499/month, and includes everything in Starter.
- Stock Option Chains
- The option chain for every F&O stock, not just the indices: live prices, open interest and its change, with Greeks computed from the market's own forward.
- Elliott Wave
- Elliott Wave counts with the cardinal rules enforced, including the level a still-forming wave has to hold to stay valid.
- Replay Lab
- Step through a past session snapshot by snapshot and see exactly what the screens showed at the time.
- Back-test Pro
- A simulated account with buying power and positions marked to market. Margin is modelled on the exchange's own basis — close, but an estimate, never the broker's exact figure.
- Alerts
- Notifications when pressure, a wall or a wave count changes, delivered to the browser.
Elite — For active stock-options traders.
₹2,999/month, and includes everything in Pro.
- Screener
- Scan the F&O universe for wave setups, and run your own Chartink scans alongside them.
What it deliberately does not do
We are not a stockbroker, and we are not registered with SEBI as an investment adviser or as a research analyst. Nothing here is a research report or personalised advice. The margin figures in Back-test Pro are modelled, not your broker's exact numbers, and the market data on our public pages is delayed. Read the Terms before you rely on any of it.
