one of the turning points in my trading came when I realized the power of MTF. When you think about it, what time frame do you think the real movers and shakers of the Forex market are interested in? The GMs, the Sony's, the Hyundais, the Toyotas, the BMWs, the Pepsi's, the Nestle's, the Samsungs et al of the world are interested in? My guess would be the weekly TF at a minimum. I cannot imagine their currency hedge portfolio managers trading the M15 or H1 or H4 TF's. No matter what anyone says, we as the retail traders are ultimately trying to ride the coat tails of these market movers. So it is prudent that we pay attention to the time frames these guys are trading at. That is my rationale.....and just my opinion.
