But we cannot use VWAP in MT4...... as none of the MT4 Brokers (GCI, Broco, BFD) provide correct volumes..... And, as Volume is the main input for VWAP, it would be incorrect in MT4....
However, in most probabilities, it should be available in your Broker Terminal (Through which you take a real trade)..... Look out for a column field called VWAP, ATP, Average Trade Price, Weighted Avg Price or by some other similar names....
And for more information on how to use it and psychology behind it..... Look out for ST Sir's Thread "Thoughts on Day/Swing Trading" in Equities>>Intraday Section of this Forum....
