Historic Data in Multi-Bars Strategy

[grasgruen]

Hello,

I have made a very simple Script:
protected override void Initialize()
{
CalculateOnBarClose = true;
// Add(PeriodType.Day, 1);
}

protected override void OnBarUpdate()
{
Print(Time[0]+": "+High[1]);
}

This does work and shows the Highs of the last 15 Days of ES 06-09 (60Min).
If I activate the Add()-Line, only the data of the last Bar is printed. Shouldn't it also work with historical data?
Thank you

Not sure I follow you. If you activate that line it will process, but it now requires you to have at least 20 daily bars before processing.

Why 20 Days?

I have now loaded 25 Days - Still same result. Only 1 Line in Output Window.

Thank you

By default, min bars required is 20 for each series. You need at least 20 bars in each series before anything will calculate. 25 days may not be 20 bars since weekends are likely included in that data set. Please increase your start/end dates to get enough data loaded.

Ok - it works now after loading 35 Days in History. Is it possible to reduce the min Bars?
The Output shows data from 25.May until now. Still not really 35 Days but only 5.

Thank you

When you start your strategy, there is a property called "Min bars required". Change that to what you want.
