# Speed Gauges

Speed gauges are useful for displaying live statistics on the price graph (since version 5.4). Up to 16 gauges can be displayed on a single price graph for multiple instruments (4 per study). Optionally, a historical graph shows values over the past minute.

Each study can display up to 4 gauges. The following summaries the configuration options for this study:

* **Location** – Specifies where on the price graph to display the gauges.
* **Show Gauge** – Toggles the display of the graphical gauge that shows the range of values.
* **Gauge Tabs** – Each tab allows for the configuration of up to 4 gauges.
* **Instrument** – Instrument used for the statistic. Check “Chart Instrument” to use the same instrument as the active chart.
* **Statistic** – The following statistics are supported:
  * **Ticks** – Number of ticks for the given interval (in seconds).
  * **Volume** – Total volume that occurred in the current interval.
  * **Bid Volume** – Total volume that occurred at the bid price.
  * **Ask Volume** – Total volume that occurred at the ask price.
  * **Delta Volume** – Difference between the ask volume and bid volume.
  * **Delta Spread** – Difference between the current best bid size and the best ask size .
  * **Delta DOM** – Difference between the total bid size and the total ask size in the DOM (Depth of Market).
* **Interval (sec)** – Interval in seconds over which to compute the statistic. Note: this is only used for some of the statistics.
* **Show History** – If checked this will show a historical graph (for the past minute) below the current value.
* **Use Gradient** – Shows a gradient (green – yellow – red) as the background on the gauge.
