Scalping is an investment technique in which trades are completed in a very short period of time, from a few seconds to a few minutes, and profits are made by repeating these trades.
There are many companies that prohibit it.
The ECN method is an acronym for "Electronic Communications Network." In the ECN method, a large number of cover traders participate, and the execution power is very high because the cover traders are automatically assigned from the huge volume of orders.
YEW Trading uses the NDD/ECN method for dealing, so it can provide high execution power without restricting scalping in principle.
