The Ticks Per Volume Bar setting specifies how many price ticks, based upon the Tick Size setting in Chart >> Chart Settings, each horizontal volume bar includes.

This controls the grouping of prices that were traded at during the specified period of time for each Volume Profile. The default is 2. This is 2 price ticks. In this case, for every two adjacent prices traded, there will be one horizontal volume bar.

For the maximum amount of detail you will want to set this to 1.

When Ticks Per Volume Bar is set to 0, it will be automatically changed to 2.

There will only be a horizontal volume bar in a Volume Profile at a price level or for a group of prices (when using a Ticks Per Volume Bar > 1), if there is trading activity at that particular price level or prices during the time period that the Volume Profile displayed is for.

In the case when you are using the Volume by Price study on a Daily, Weekly or Monthly Historical chart, we do not recommend setting this to 1. You should use a higher value somewhere between 4 to 10. Otherwise, CPU load could increase significantly. Additionally for these types of charts, select Chart >> Chart Settings and set the Volume at Price Multiplier somewhere between 5 to 10 to decrease CPU load.

When the Chart >> Chart Settings >> Volume at Price Multiplier is set to a value other than 1, then the Ticks Per Volume Bar setting needs to match it or be a multiple of it. For example, if the Volume at Price Multiplier is set to 5, then set Ticks Per Volume Bar also to 5 or a higher even multiple like 10 or 15.

If you find that the Ticks Per Volume Bar setting changes from the value you set it at, this is because the Chart >> Chart Settings >> Volume at Price Multiplier is set to a value other than 1 and it is automatically being changed to a multiple of the Volume at Price Multiplier.
