That would no longer be the strategy that he wants to deploy, obviously. Look, I've wasted more than enough time engaging with you. You're clearly more interested in arguing (trolling) than in helping. Over and out.
Case closed, byeos! 
I suggusted the same previously. But this was not what the OP was looking for.Hmm. but he writes the following, and I think he does not understand that the problem is his position size of 10k, and not the 10 positions he seems to think...If he takes position size 5k then he can place 20 positions... he even can use all 40 by splitting the avail capital accordingly... simple allocation maths...
Why don't you just add a condition to the 40 limit orders.
E.g. Limit 10 for stock ABC with condition ABC Last <=10.02.
Order will be held by IBKR and only sent when ABC below 10.02.
This way you avoid having too many active orders and only the ones likely to fill will be transmitted.
This can be done easily in the order ticket.
PS: you might even improve your fill quality by controlling for large moves in a benchmark index. You probably dont want buy fills when overall market slides...
