How does a broker know you are (consistent) profitable ?

[TrAndy2022]

This question is crucial for any FX broker to know whether you should be A-booked or B-booked as trader. But how do they know this when to hedge their position to other counterparties ? What kind of trading statistics you need therefore ? What do you think or assume here ? When do you know as trader you get A-booked instead of B-Booked (more slippage or anything else ?) on a FX broker ? Let me know your thoughts and insights please.

It is the transaction that is usually A-booked or B-booked. There might be exceptions.

I know, but how do you know this as trader ? When does a broker decide on what criterias to do this ?

With exception the trader is not automatically booked A or B.

So broker knows where FX market will go?
Or they are simply keeping their books in balance?
