Brokers that strictly forbid option buying using collateral margin

Need to find list of brokers that do not allow option buying using pledged margin. I need this setup so that I do not end up buying huge quantities of options from the pledged margin i get from my securities that I want to strictly use for option selling only. This used to be the case earlier with many brokers but not anymore.

I end up buying options as a result of revenge trading. I need to a setup which just does not allow it so all my capital from pledged securities is for option selling only.

Fyers is not suitable for you.

Shoonya or flattrade might work for your use case. They are decent brokers but they do have some drawbacks too.

flattrade does not pick up customer support phone, does not allow MIS trading in non-F&o stocks

Shoonya delays funds settlement after equity sell , means we cant reinvest money same day.

you can also use a separate account for option buying.
