Re: Ela code and FP error

[editorial@xxxxxxxxxxxxx]

Just reading through code (1) (not testing it) I note that you're really trying to create two PaintBars, one for the upside and one for the downside.  But every PaintBar in TS4 requires two Plot statements.  For example, you can write:


If switch=1 and low<=Lbb then begin
  Plot1(Low,"Lo");
  Plot2(H, "Hi");
  Switch = 2;
End;


So if you want different colors for your paintbars you may wish to create two separate studies... or you can create one study and use the same two Plot statements for both upside and downside...  But the PB's in this case will be the same color...
