VPOC stands for Volume Point of Control and is the price level with the heaviest volume for the day. This is the price level with heavy Acceptance by both, Buyers and Sellers. The level signifies agreement by both parties on Value. Now, if the Buyers and Sellers agree that a certain price is fair, then the market could remain in balance trading around the VPOC until additional information changes the perception on Value or it could head in the opposite direction and test a previous area of Rejection (disagreement). VPOCs serve as great targets.
But how do you trade it? On a Non-Trend Day price could just rotate around the VPOC until new information (a catalyst) is introduced in the market and changes the opinion on Fair Value. The idea is to fade the extremes of the range around the VPOC. On a Trend Day, Price will make a directional move away from Value and Value will catch up to Price so any pullback will probably be bought before the VPOC could shift again (double-distribution trend days).
