Zerodha,
I have a query regarding options writing. Why is additional margin blocked when a Stop loss buy order is placed to cover the intraday(MIS) option sell trade?
For example:
I sell 20 lots of 6000 CE for intraday(MIS) when the option price is 50 Rs at market price. The margin blocked after this trade is say 50K. Now I want to close this trade if the option price reaches 70Rs. So I place a MIS stoploss Buy order of 20 lots with trigger price of 70Rs. When this order is placed, in addition to the 50K blocked, an additional 70K margin is blocked.
When the SL buy order is executed at trigger price, the previous sell position will be squared off. So why is additional margin blocked? Is it because the web version(trade.zerodha.com) allows only SL limit orders and not SL market orders?
Thanks
