The Volume Delta Footprint
identifies who is in control of the current bar. In the above chart, -5 represents the fact that there are more sellers built into that bar at the current time. The lower Footprint
(red rectangle) with a reading of [8x3] shows us that sellers are in control and that there are 8 sellers and only 3 buyers built into the current bar. The indicator plots the cumulative bars delta for intrabar analysis. There is no need to plot the data for all bars, only the current bar.
Volume Delta (Change In Volume) = Sellers - Buyers
The Volume Delta Footprint indicator can be used on any timeframe and can be handy when tracking Daily bars to know if there is an imbalance (an up bar with neutral to negative delta), or especially useful for scalping on small timeframes when intrabar decision must be made.
