Multiple Data Series

[WaleeTheRobot]

I'm considering adding multiple data series to an indicator, but it seems that dynamically adding values to AddDataSeries is not recommended. Is having some checkboxes when loading the indicator a good approach to allow a user to select if they want enable a certain data series? This will allow a user to select predetermined default additional data series, but not take up memory if they don't want to use a certain data series. At least that's the idea behind it.

else if (State == State.Configure)
{
    // Checkbox from properties
    if (fiveMinuteEnabled)
    {
        AddDataSeries(BarsPeriodType.Minute, 5);
    }
    else if (fifteenMinuteEnabled)
    {
        AddDataSeries(BarsPeriodType.Minute, 15);
    }
    
}​

Hello WaleeTheRobot,

Using a condition to call AddDataSeries() is still dynamic.

Instead of dynamically choosing if a data series is loaded, which can cause errors in some situations (like when optimizing or hosting a symbiote), we would recommend statically hard coding the AddDataSeries() call and then in OnBarUpdate() deciding if you want to use the data.

protected override void OnBarUpdate()
{
if (fifteenMinuteEnabled == false && BarsInProgress == 1)
return;
}

You could also choose to dynamically add a custom new Series<double> and dynamically pump data into from a BarsRequest.
Below is a link to an example.
