Some clarification on Add()

[suprsnipes]

When loading an additional chart series (for example, AddKagi, AddLineBreak, AddPointAndFigure and AddRenko) within a strategy does it still build OHLC. Would you be able to use the open high low closes X number of bars back? The reason I ask is from reading the Help section it says possible values are MarketDataType.Ask, MarketDataType.Bid, MarketDataType.Last?

Thanks in advance,

I have made some progress with the Add() and would like to know what would be causing the following error with this line of code;

Close[1][3] < Open[1][3]

Cannot apply indexing with [] to an expression of type 'double'.

I'm trying to access the barsAgo [1] in a multi-instrument strategy [3]. How can I access this without the error?

Hi suprsnipes, in MultiSeries strategy you would use :

Closes[1][3] < Opens[1][3]
