Volume Delta (Vol ∆)


The Volume Delta (Vol ∆) study displays the total amount of transactions occurring on both the Bid and the Ask in a given interval (similar to CBAVol), but also superimposes the absolute value of the net difference between the BVol and AVol for that interval. Whichever is greater (BVol or AVol) is displayed in that color on top of the total volume.


Bid/Ask Volume Tick = Number of transactions at the Bid and the Ask

Bid/Ask Volume Actual = Number of contracts traded at the Bid and the Ask

Additional display line = | BVol - AVol |, color represents whichever is greater (BVol or AVol)
