After an open positions, partial positions how run?

[cKTIMER]

Hello , I want to ask a question. After an open positions, partial positions how run?
for example,After an open positions, 1/2 positions use ratio 1:1（TP:SL）, 1/2 positions use ratio 3:1 （TP:SL）

MetaTrader 4: each "position" is unique and it has it's own SL and TP
MetaTrader 5: you can have only 1 position per symbol (market) and that position can have only one SL and only one TP at a time. No, you can't have multiple SL and TP here.
