A true pricing environment is the very best for scalping, since there is no broker that is manipulating the prices of currency pairs when in a trade, the trader can go in and out as frequently as they want getting only a few pips a trade, also the bank never takes risk, therefore scalping causes no concern for every trade is offset either on the EBS or through another major bank, this is the only trading environment where a scalper could actually come out ahead in most trades.
