Hi Joe
I also struggled with this, however I eventually found there is a
very simple solution where you create a composite symbol. See my
example below for a Dow-Gold ratio:
OpenDowGLD = Foreign("^DJI","Open") / Foreign("GLD","Open");
HighDowGLD = Foreign("^DJI","High") / Foreign("GLD","High");
LowDowGLD = Foreign("^DJI","Low") / Foreign("GLD","Low");
CloseDowGLD = Foreign("^DJI","Close") / Foreign("GLD","Close");
AddToComposite( OpenDowGLD, "~Dow-GLD", "O", 1 + 2 + 8 + 16 );
AddToComposite( HighDowGLD, "~Dow-GLD", "H", 1 + 2 + 8 + 16 );
AddToComposite( LowDowGLD, "~Dow-GLD", "L", 1 + 2 + 8 + 16 );
AddToComposite( CloseDowGLD, "~Dow-GLD", "C", 1 + 2 + 8 + 16 );
Buy=Sell=Short=Cover=0;
Filter=1;
The tickers are based from Yahoo data - you simply view the symbol
~Dow-GLD
An alternative if you want to create a chart that displays alongside
your current symbol is to create an andicator like this:
ticker = ParamStr( "Ticker", "GLD" );
OpenSpread = Open / Foreign(ticker,"Open");
HighSpread = High / Foreign(ticker,"High");
LowSpread = Low / Foreign(ticker,"Low");
CloseSpread = Close / Foreign(ticker,"Close");
PlotOHLC( OpenSpread, HighSpread, LowSpread, CloseSpread, FullName()
+"-"+ticker+" Spread", colorBlack, styleCandle );
Hope that helps
