Min Number of BarsBack for Indicator Plotting

[fwalton]

I was working with a generic indicator as described below:

Initialize()
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
CalculateOnBarClose = true;
Overlay = true;
PriceTypeSupported = false;

OnBarUpdate()
Plot0.Set(Close[0]);

When the indicator is first added to a chart it renders fine.
however, if I use 'Format Data Series' and set the 'Bars Back' to anything less than 23, no indicator lines are drawn.
The same behavior applies to every time interval.
According to the info I logged, the OnBarUpdate event is firing for every bar, but the first 23 bars are ignored, and then the indicator begins plotting.

Is there a setting to force the indicator to draw on every bar when Bars Back is set?

Thx.

Fred,

Try setting BarsRequired to 0.

Perfect.
Note: The property is not in the Indicator Setting dialog box like it is for Strategy Settings, but it does work in code.

BarsRequired = 0;

Your observations are correct.
