 BookMep has offered volume data columns for many years. This current chart range volume profile, or CVP column, is configured as a profile composite of both aggressive buying and selling for the current viewable chart range. When you right-click on the column and select Configure, under Style Options you can choose to split out the aggressive buying and selling volume. This is very helpful to see which aggressor might be dominating the price action. However, now there is a new feature that will display buy minus sell volume. This is the volume delta. To display the delta, right-click in the column and select Configure. Under Visual Options, select the delta box. Let's also deselect the split display option and close the window. Now you can access the volume delta within the profile composite. This is a very simple but extremely insightful visualization of the market data. See how nicely the delta column now clearly displays sellers in control and dominating price action below this area here? Also note how buyers are dominating above that area as well. This leads to many interesting insights. For example, what if buyers can quickly move price away from the lows and then begin trading above this area? They will trap the sellers and possibly be able to create a short squeeze to the upside to test high liquidity at the upper ranges. Note this delta display feature also works for the trades counter and quotes counter data columns as well.
