The problem I see with cutting a loser based on size or floating PnL is that you have no idea whether the pair you're cutting is the pair that is going to bring your basket to profit.
Why not use the phantom logic to chose which pair to cut? Eg:
(a) do a reverse of the phantom buy - cut 1 pair based on the worst performing pair in the basket(*)
(b) keep a record of the phantom buys, and cut the pair that was a phantom buy last out of all the pairs
(*) has this been suggested before?
