Looking for Software for Future Position Conversion

#1
Hi guys,
i trade in the future segment on NSE, and every month i carry postion from one month to next. the problem or the time consuming part is that i have to manually convert each lot individually as the price suites me.
I was wondering if i could get some software which could automate the process. But i also want to be sure that no blunder (like what happened in US last week) should happen. I am using NOW to do the trades.

Regards
Aman
