Sachin...Please look into this. I was trying to sell 5900 CE via cover order for Rs. 19.00............the system wanted me to keep an SL between 19.20 & 19.30..........isn't that strange...most likely both my original order and SL order will be executed together......1.5% range for SL for options is too less...Cover order then absolutely doesn't make any sense.....it should be 1.5% of strike price ideally instead of the LTP in case of options...only then would it make any sense....if this is not possible, you should come up with something more rationale...I dont think it makes any sense for me to sell option at 19 and put a stoploss of 19.20.......I am sure you will agree....
