Please let me know why is this buy option requesting for margin more than the buy price.
We are in Expiry week, so during this period Long ITM Options need additional margin as per exchange requirement.
- The Exchange charges physical delivery margins as a percentage of applicable margins(VaR + ELM +Adhoc) of the underlying stock which is levied from expiry minus 4 days for long ITM options
Can check this for more info.
