Description

This study displays the difference between the Ask Volume and the Bid Volume for each chart bar. The value of this difference at Index \(t\) is denoted as \(V^{(ask)}_t - V^{(bid)}_t\), and it is displayed on the chart as text.

The text is displayed below each bar. Let the Offset in Ticks Input be denoted as \(k\), and let the Tick Size be denoted as \(s\). Then the location of the text containing the value of \(V^{(ask)}_t - V^{(bid)}_t\) is determined by \(L_t - k \cdot s\), where \(L_t\) is the Low Price at Index \(t\).

The coloring of the text is controlled by the Subgraph Primary and Secondary colors. For more information, refer to Studies >> Subgraphs Tab >> Color.

Depending upon the Data or Trading service you are using, you may not receive historical Ask Volume when historical data is downloaded from the service. Not all services will provide this.
