Combined Chart with param function

[amisur]

Hello,

Is it possible to get setforeign values from a watchlist using param function and make a comined chart with OHLC values?

A chart that represents the sum of two symbols, was: Adding two scripts

It was kindly pointed out to me that it wouldn't be accurate to add the high and low values of the two different equities. Even though I'm using daily bars, the two different highs could be occurring at different times of the day as well as the two different lows. The open and close happen at the same time each day for both equities, so you could combine them. This is my corrected AFL where I only chart the added open and close for the two equities: SetForeign("NUGT"); Open1 = Open; Close1 = Cl…

SetForeign("NUGT");
Open1 = Open;
High1 = High;
Low1 = Low;
Close1 = Close;
RestorePriceArrays();

SetForeign("DUST"); 
Open2 = Open;
High2 = High;
Low2 = Low;
Close2 = Close;
RestorePriceArrays();

CombinedOpen = Open1  + Open2;
CombinedHigh = High1 + High2;
CombinedLow = Low1 + Low2;
CombinedClose = Close1 + Close2;

//Exploration
Filter = 1;
AddColumn(Open1,"Open1",1.2);
AddColumn(Open2,"Open2",1.2);
AddColumn(CombinedOpen,"CombinedOpen",1.2);
AddColumn(High1,"High1",1.2); 
AddColumn(High2,"High2",1.2); 
AddColumn(CombinedHigh,"CombinedHigh",1.2); 
AddColumn(Low1,"Low1",1.2);
AddColumn(Low2,"Low2",1.2);
AddColumn(CombinedLow,"CombinedLow",1.2);
AddColumn(Close1,"Close1",1.2);
AddColumn(Close2,"Close2",1.2);
AddColumn(CombinedClose,"CombinedClose",1.2);

//Charting
SetChartOptions(1, chartShowArrows | chartShowDates); 
_N(Title = EncodeColor(colorAqua)+"Combined" +EncodeColor(colorWhite)+StrFormat(" {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) {{VALUES}} ", CombinedOpen, CombinedHigh, CombinedLow, CombinedClose, SelectedValue( ROC( C, 1 ) ) ));
PlotOHLC( CombinedOpen, CombinedHigh, CombinedLow, CombinedClose, "Combined", colorDefault , styleCandle);

Thank you
