Please leave that to discretion of Traders.
It is upto individual traders to use different strike price for any Strategy.
Where is equality between traders. Guys on other platform would able to trade in these strike prices and execute strategies ?
It is like there was a traffic jam or some problem created in particular road do you stop vehicle movement or put some traffic rules and regulate traffic ( bad example ). Blocking a particular option strike does no good.
It is the problem of particular trader who has shared his password to others and got misued/cheated. That doesn’t mean you block everyone that opportunity.
Does SEBI even allow you to block few options from Regulation point of view . There is reason for everything.
@nithin : please look into this. What is your opinion on this.
@others : please pitch in your views. It is denial of the right of trader and an opportunity missed.
