here's paintbar code for PST SPoos, etc:

IF  time>= 1314 and time <=1315 Then Begin
  Plot1(High,"PBHigh");
  Plot2(Low,"PBLow");
  IF CheckAlert Then Alert = TRUE;
End;

Of course it doesn't work on early closes,
markets with no last minute ticks, etc.

I'll let Gary collect the meal since
he's within driving distance of Tom.
