AddVolumetric TickPerLevel

[sdauteuil]

I am using a secondary series 15 minute volumetric bar

When adding the volumetric there is a parameter for ticks per level

AddVolumetric(string instrumentName, Data.BarsPeriodType baseBarsPeriodType, int baseBarsPeriodTypeValue, Data.VolumetricDeltaType deltaType, int tickPerLevel)

I want to have this set to 8 ticks but if I try to return a value for delta I return zero.
GetDeltaForPrice(double price)
If I set to one tick I return the proper value. I am assuming it is returning zero when set to 8 ticks is because this is trying to return a value for a specific price level as opposed to a span of prices.

I would like to return the sum of delta for 8 ticks surrounding the Close[0] price.
Do I have to manually sum the 8 ticks?

On a second note when I set TickPerLevel to 1 for a 15 minute bar I cannot visually see all the price levels on the chart, they are too small to read. When I stretch the screen many of the price levels go out of view. See attached

I am trying to verify the strategy is returning the correct delta at the corresponding price level. Is there a way to scroll the chart so I can read all the price levels?

Thank you appreciate the effort

One more question

CurrentBar is an index what is the proper syntax to access previous bars?

Print("Total Volume: " + barsType.Volumes[CurrentBar].TotalVolume);

Hello sdauteuil,

[CurrentBar - 1] would be the previous bar.

Hello sdauteuil,

Including TicksPerLevel from BarsPeriod.Value with the loop will give the expected output.

for (double rowPrice = Low[0]; rowPrice <= High[0]; rowPrice += TickSize * BarsPeriod.Value)
