Support/resistance rectangle that extend on last bar

  Hi I was wondering if anyone could help me… I’m trying to write an indicator that will find a rectangle on the chart and extend it out to the current bar.  I want to draw supply and demand zones myself using the rectangle, but I want it to automatically extend (and stay updated) to current bar.

  Any ideas?

  Hi Rudy, I moved your query to a new specific thread.

  To draw a rectangle that will always be drawn to the last bar, you must use the BARINDEX instruction as the second X-axis coordinate, like this:

  Example of a support zone:

  x1 = barindex-50 y1 = lowest[50](low)[1] DRAWRECTANGLE(x1,y1,barindex,y1) COLOURED(255,0,0,100) RETURN

  1 2 3 4 5 6

  x1 = barindex-50 y1 = lowest[50](low)[1]   DRAWRECTANGLE(x1,y1,barindex,y1) COLOURED(255,0,0,100)   RETURN

  Thank you Nicolas!  Do you know how I would get the indicator to only apply this extension to a manually drawn rectangle?  I don’t want it to draw a rectangle on its own, only extend the ones I draw.
