Start from a pre-defined structure, or build from scratch. Pick strikes off the live chain, set your profit target and stop-loss, back-test on real data, then run it in paper or live.
Start from a structure
A starting point, not a recommendation. Applying one fills the legs below — every leg stays editable.
The sketch on each card is the shape of its payoff at expiry — profit above the dotted line, loss below. It is drawn to illustrate the structure only: it has no scale, uses no market prices, and is not an estimate of any outcome.
Basics
No chain available for NIFTY.
Payoff at expiry
Pick strikes with B / S in the option chain above — the payoff prices off real premiums.
Legs
No legs yet — click B or S on a strike in the option chain above.
Entry
Enter on an indicator condition, or simply at a set time. Positional structures like a ratio spread are defined by WHEN they go on, not by a bar pattern.
Enters as soon as it starts — today if you start it during market hours, otherwise at the open on its run day. The order is placed as a limit just past the market price, aiming to fill straight away — a fill is not guaranteed.
Exit, target & stop-loss
Stop-loss and target are optional, measured on each leg's own premium from its entry price. The exit time always applies.
Advanced — trailing stop and re-entry
Back-test, save, and run
Back-test runs on real historical data. Paper runs the same rules live without money. Live requires a connected broker, a free slot and a static IP.
Runs
Back-test and run both save the strategy for you first — you do not have to save it yourself. Paper and live are independent: you can go straight to live.
