I am trying to get the high and low of a given bar that i click the mouse on. I understand using the ProcessMouseEvents and all that. But I have a hard time getting the values for the bar clicked...

I am trying various ways, but with no luck. .. Sometimes I am getting vBarsAgo as a number less than 0, so I am not sure what I am doing wrong, or how I should approach the problem..


Here is rough pseudo sample code

 
Code
if MouseClickShiftPressed then begin

   vClickBarNbr = MouseClickBarNumber;
      

   
 //vLastBar = currentbar;
   vLastBar = barnumber;
   vBarsAgo = vLastBar-vClickBarNbr ;
   if vBarsAgo >= 0 then begin
      vClickBarHigh = high[vBarsAgo];
      vClickBarLow = low[vBarsAgo];
      print ("high = " + NumToStr(vclickBarHigh,2) + " Low = " + NumToStr(vclickBarLow,2));   
   end
   else begin
      print ("bar= " + NumToStr(vBarsAgo,0) + " Low = " + NumToStr(vclickBarLow,2));
   end;

   end;

Why don't you try to get the bar by time, you should be able to get e.X as time pretty easily...

you are using a non-standard bar chart.
