"rockyhoangdn".... the chart with your code does not draw a new bar automatically... has to be refreshed manually... It also repaints a number of bars.

find:
ArrayResize(UpDown,limit); 

and replace with

ArrayResize(UpDown,Bars);

thanks, but this chart works fine... limit or Bars.. both work... I was referring to the other chart " Grossperiod 60" it does not auto refresh and also repaints. I'm not a coder but I guess it is possible to code it so it does not repaint history bars.

It will auto refresh with "Bars", but if use "Grossperiod 60" its allway repaint.
