Restricting to 10 positional trades at a time in a List

Strategy
#1

Hi,

I want to write a positional algo on Nifty 50 list. I would like to have max 10 positions open at any point in time.
e.g. on day-1, I enter 3 positions which satisfy a criteria
on day-3, 12 stocks satisfy the criteria, but I want to enter into only 7 of these so that max 10 positions are open at a time.

also when I exit few stocks based on some criteria, I would like to enter again for the remaining open positions upto 10 when entry condition occurs.

How to achieve that?

try using the ‘Open Positions’ (under Strategy Info category) keyword to check before entering a new trade.
I believe this is at a strategy level, hence should solve your problem.
