I think if Zerodha has to stand out from other trading platforms, they need to come up with some smart features. One of them is to give exit feature for options based on the underlying (fut or cash).
For instance if I bought “Rel infra 120” when CMP is at 115, there should be an exit feature for me to place like Exit Rel infra BUY call when CMP reaches 120.
Because most of the option traders have a view in the underlying instead of option itself. This will be incredibly useful for professional option traders. @nithin@siva
Use sentinel for trigger, when the alert triggered you will get message on platform and with two clicks one can place order, that is the best possible available for now, for retailers in India I can say.
