I feel even embarrassed asking this but what's the best site/videos to refresh options trading in the Indian context? I might want to dabble a bit in them... I hated derivates while studying CFA so I barely remember anything.

Yes it should be LTF. I have Sapphiro for about 3+ years now and have only used if it there an offer on ICICI's card that is not available elsewhere, or if I want the BMS BOGO.

Oscar is garbage. Yup

Nice
