Worst platform.....Happend in May 03,2018....today again the same issues. .......i am unable to put trades nor able to square off on such panic day. At one point of time my accounts shows margin of 1.05 Cr??? At the down time if u call them .... no one response on that. You cannot execute any trade. Also they dont allow to sale any options. ....No reason for that. Not recommended to any one
