Adding indicators from different TF to current chart

[lifzgreat]

I'm viewing the 15 minute TF but would like to add EMAs from the 1H time frame to my chart programatically. In initialize(), I'm using:

Add(PeriodType.Minute, 60);
Add(EMA(BarsArray[1], 8));
Add(EMA(BarsArray[1], 34));

When I try to start the strategy, the log displays the following error:

'BarsArray' property can't be accessed from within 'Initialize' method

I understand what it's saying but how else am I supposed to add the indicator from the 1H time frame without doing it manually?

lifzgreat, I would suggest you create a MultiSeries indicator first for the MA's and then Add this indicator completely in your Strategy Initialize() method instead.
