Hi: I am working with MetaStock 8.01 Professional. I am creating a backtest in which I would like to use let's say Moving Average Crossover of the 20 and 50 day MA of a composite which I created IWM/SPY (divide IWM's by SPY's to determine relative strength of the two ETF's). I want to run the System Backtest against another composite (IWM - SPY) to get an idea of the returns which would be generated by going long IWM and simultaneously shorting SPY. I tried doing this by referencing the composite with the Security Data Function but an error message indicated that there is no such thing as a composite in this function. I then tried to synthetically do this by using the following formula: Security( "IWM", MOV(C,20,E)/Security( "SPY", MOV(C,20,E) > Security( "IWM", MOV(C,50,E)/Security( "SPY", MOV(C,50,E))))) I receive error messages doing this as well. My question: Is there a correct way to reference a composite and embed it in the formula above? Many thanks for your assistance.

That you for your quick respond. I was under the impression that because the composite IWM/SPY is located in the same folder as the base securities (IWM and SPY), then referencing using the full path was not necessary. However, I certain am not adverse to giving it a try. Thanks again - I'll post whether this is sucessful in a little while.
