[amibroker] Re: How do I get the price and indicator values in the custom backtester?

["Mike" <sfclimbers@xxxxxxxxx>]

I can't test this out at the moment. But, try either of Foreign or 
SetForeign. Generally, when making multiple references to a foreign 
symbol, you would use SetForeign for better efficiency compared to 
multiple calls to Foreign.

SetForeign(sig.Symbol);
sig.PosSize = CurrentEquity * Ref(C, -1) / Ref(ATR(10), -1);
RestorePriceArrays();
