19. Legs: strike by ATM, delta or premium

Every strategy is built from legs. The quickest start is a template: here, an iron condor.

Each leg is a buy or a sell, of a call, a put or a future, with its number of lots and its expiry.

Then choose how its strike is picked: by steps from the at-the-money strike, by delta, or by premium.

For example, by premium: sell the call that's priced nearest to 50 rupees.

Add leg adds another one. You can copy a leg to repeat it, or remove one you don't need.
