Volume By Price (VOLBP)

Printer-friendly versionPDF version

Volume By Price is an overlay that shows the amount of volume for a certain price range. It is shown by horizontal bars based on the current data of the chart. The drawn bars span the price range, meaning that all volumes within that range are added to that bar. Chartists can use Volume By Price to provide support or resistance based on the high volume price ranges.

Volume By Price can be used as a support and resistance identifier. That is because larger volume at a certain price range shows higher interest in that price range. This interest can influence future supply and demand such that if the price goes to far away from the interest range then the price is likely to return to that range. Therefore, if an arrow is thrown by another indicator and the arrow is near a peak or valley in a low interest (low Volume By Price area) and the arrow points toward the higher interest price range then it can be said that the arrow is more likely accurate or supported.

Calculation

Volume By Price calculations are based on the current chart screen and the price bar being displayed. That means that if the price bar is on the screen then it's volume is taken into account and if the price bar is not on the screen then it's volume is not taken into account. Know also that to be taken into account the close price for the price bar needs to be on the screen. The current chart screen is divided by the number of bars to get the price ranges for the Volume By Price bars.

A Volume By Price bar is broken up into down volume (darker default color) and up volume (lighter default color). Up volume is when a price bar's price is greater than the open and down volume is when a price bar's close is less than the open.
