[amibroker] Re: changing entry price in CBT

["Mike" <sfclimbers@xxxxxxxxx>]

If you want to keep the CBT code, then you will have to use Foreign or SetForeign to indicate that you want to use the arrays associated with the symbol of the signal (as opposed to ~~~Equity).

e.g.
ForeignOpen = Foreign(sig.Symbol, "O");
ForeignClose = Foreign(sig.Symbol, "C");

sig.Price = ForeginOpen;
...

or

SetForeign(sig.Symbol);
sig.Price = Open;
...
RestorePriceArrays();
