Yes these are all valid scenarios and we were thinking the same -- but the RMS software isn't advanced enough to handle all this. Another thing is that you only get 5 levels of depth of data with the NSE. Now, what if your quantity exceeds the total amount of quantity shown on the top 5 levels? Then RMS becomes even trickier to calculate.
What your RMS can do I can't understand, earlier you said it can't handle intraday margin for option writing, now it can't handle market orders......... what's else remaining........ after few months you will tell us that it can't handle SL orders ???????? :annoyed::annoyed:
