Re: [amibroker] scaling issue with PlotForeign() and bollinger bands

["Steve Dugas" <sjdugas@xxxxxxxxxxx>]

Hi Charles,
 
bBot, bTop and indClose are plotting correctly. 
Plotforeign statment appears to be using its own scale, but if you add 
Style argument it falls into place. Try this code to see:
 
baseIndustry = GetBaseIndex();
 
indClose = Foreign(baseIndustry, 
"Close");
 
bBot = BBandBot( indClose, 20, 2 );bTop = 
BBandTop( indClose, 20, 2 );
 
Plot ( bBot, "BB Bot", colorBlue ); Plot ( 
bTop, "BB Top", colorBlue ); 
 
Plot (indClose, "Ind " + baseIndustry, colorWhite, 
styleDots);PlotForeign( baseIndustry, "Industry " + baseIndustry, colorRed, 
styleCandle );
 
 
Steve

  Subject: [amibroker] scaling issue with 
  PlotForeign() and bollinger bands
  When reviewing stocks, I'd like to plot their industry 
  indices as an indicator. In the industry graph, I tried to plot it 
  bollinger bands as well.I used the following coding, but found out 
  the BB lines and industry index graph cound not be align properly. The 
  reason seems to be different scaling, as I can see the values of BB and 
  index close are correct.baseIndustry = 
  GetBaseIndex();indClose = Foreign(baseIndustry, "Close");bBot 
  = BBandBot( indClose, 20, 2 );bTop = BBandTop( indClose, 20, 2 
  );Plot ( bBot, "BB Bot", colorBlue ); Plot ( bTop, "BB Top", 
  colorBlue ); Plot (indClose, "Industry " + baseIndustry, 
  colorRed);PlotForeign( baseIndustry, "Industry " + baseIndustry, colorRed 
  );Any help is appreciated.CharlesSend
