Here's a chart which when studied closely will tell you how to plot moves in the market based on whether the big boys are trading or not.
As we all know, when institutional interest is present in the market, the movement will be quick. In Market profile we call this OTF ( Other time frame).
The Other time frame is simply all traders who are not trading our time frame which is the day and swing. This would include banks, brokerages, pension funds and other institutions.
We call ourselves the "Locals" as we trade the day time frame and make up the small movements in the market.
