Restriction on stock list

Hi

I want to do paper trade for Nifty 50 FnO stock (which contains 50 stock) But it seems that there is restriction as strategy. goes in blocked status saying that restriction in resource condition found . When I checked with TT Team they are saying one cycle takes 50 sec so it time limit exhaust then it goes in error. Also they are saying that it will work only live deployment. I am confused here. Do they mean that 50 sec restriction per trade cycle is not there only for Live Trade?
Do any one works with Live Trade with Nifty50 FnO stock ? Does it works correctly or you have to reduce no of stock from list?
