How to draw the Horizontal Line (Custom Indicator shows Dots)

[pffx]

Hi,
I have imported the Custom Indicator that shows me SnR Levels like a dots (Red for Support and Blue for Resistance) and I need to find these dots on the chart and create Horizontal Line (an infinity) from the past 2000 (depends on the timeframe) candles to the actual candle.

1. Indicator is visible -> Draw Line

Somebody does have an idea how to do it?

Thank you

I know this doesn't answer to your question the way you want, but... modify the indicator itself to do that

This indicator is not mine. I have only .ex4 file.
