Option Strategies
Option Strategies is a strategy builder on top of a replayable option chain. Build a multi-leg position, see its payoff, greeks and margin, then step through a past session bar by bar to watch how it would have behaved.

Loading a session

Search and select the underlying, then choose the expiry and how many strikes to show around the money.

The chain, the payoff and every figure update to the bar you are on.
The historical option chain
Calls on the left, puts on the right, strikes in the centre, each with OI, LTP and an Analysis tag. Hover an LTP cell for its actions: add a buy leg, add a sell leg, open the contract's chart, or add it to a watchlist.
Building a strategy
Add legs from the chain, or use Quick build:
- Choose a view — Bullish, Bearish, Neutral or Others.
- Choose a strategy. The bullish list, for example, includes Buy Call, Sell Put, Bull Call Spread, Bull Put Spread, Call Ratio Back Spread, Long Calendar with Calls, Bull Condor, Bull Butterfly, Range Forward and Long Synthetic Future.
- Set the Width (strike spacing between legs) and press Add strategy.
Each leg can then be edited: Side (buy/sell), Type (call/put), Strike, Lots and Entry price. Save basket keeps the set of legs; Clear removes them.

Days for which the historical contracts cannot be loaded are skipped and listed with the reason, and are excluded from every statistic. Check the number of days actually traded before reading the results.
