I added a line to get the tickers from a Watchlist.
Seems to work.
/*
Nominate a data padding reference symbol in AA settings.
Select the reference symbol as the current chart.
Right click and use the parameter options to view any symbol, other
than the reference symbol, in padded mode.
Selecting the same symbol, as the current chart and in the parameter
dialog box, will display the symbol in non padded (normal) mode.
Daily, or Weekly views etc function as usual, in padded mode, except
that
any week containing a padded daily bar will be compressed selectively
and not in total.
*/
//List = "^DJI,CAT,A";
List = CategoryGetSymbols( categoryWatchlist, 0 );
Select = ParamToggle("PadData","No|Yes",1);
Ticker = ParamList("Tickers",List,0);
SetForeign(Ticker, Select);
Plot(C, "SetForeign" + " - " + Ticker, colorRed, styleBar );
RestorePriceArrays(Select);
