Suppose I keep a "Buy above" order for a Call option and another one for a put, and suppose the call option gets exercised, can I cancel the put order ??
And if the call gets executed, can you cancel the put? If that's the question, then the answer is no. It's treated as a single order so you can't cancel one leg and keep the other. For that, you have to send it as two separate orders to the exchange.
