This is a script born out of necessity. It lets you put horizontal lines on your chart at 25, 50, or 100 pips... 

Just select the type of a line, color, thickness and how far each way from the current price you want it to put them.

You can select if you want them on the foreground or background. However, if the chart is set to the foreground, it will take precedent.

Download it today and start using it. I use this everyday for the last few years.
