Volumes

View as Markdown

Definition

Holds an array of ISeries\<double\> objects holding historical bar volumes. An ISeries\<double\> object is added to this array when calling the AddDataSeries() method. Its purpose is to provide access to the volumes of all Bars objects in a multi-instrument or multi-time frame script.

For working with Cryptocurrency instruments which report volume fractional, please use the VOL() indicator series, or store the volume for your script in a custom variable and convert alongside our VOL() indicator Instrument.MasterInstrument.InstrumentType == InstrumentType.CryptoCurrency ? Core.Globals.ToCryptocurrencyVolume((long)Volume[0]) : Volume[0]).

Property Value

An array of ISeries\<double\> objects.

Syntax

Volumes[int barSeriesIndex][int barsAgo]
