How to draw disconnected lines?

[ale]

I am creating an indicator where the values change dramatically then the day changes. 

The problem is that the lines drawn by MT4 with the values in the indicator buffers connect all the points, so the last value of day A is connected to the first value of day B and the result is ugly.

Is it possible to stop MT4 from drawing this ugly connection line from a certain point to another?

Lines connect, don't use lines. Use

   SetIndexStyle(0,DRAW_ARROW);
   SetIndexArrow(0,159);

like Parabolic.

Nice trick, thank you.
