Any Idea why the chart plots bars instead of candlesticks with the 
  
following formula I use in order to change their color?
rule1= O 
  < C;
rule2= (O < C) AND (C > Ref(H,-1));
rule3= O > 
  C;
rule4= O > C AND C < Ref(L,-1);
rule5= O = 
  C;
paintbars=IIf( rule2, colorLime, IIf( rule1, colorGreen, IIf( rule4, 
  
colorRed, IIf( rule3 , colorBrown, colorWhite))));
Plot( C, 
  "close", paintbars, styleCandle );
Thanks
