ES S/R Levels

This script plots support and resistance levels for /ES on your chart.
This script only works on the /ES symbol in Tradingview due to the string manipulation of the levels.

You can input support and resistance levels in the inputs.

The example format of S/R levels should be in the following form (comma-separated)
If the level is a single point, it will draw a line. If the level is a range, it will draw a box.
4260, 4267, 4275, 4283, 4289, 4297-4300, 4310-15, 4325-30

You can also add the keyword (major) in your S/R levels input which will add a (Major) label to the drawing
4260, 4267 (major), 4275, 4283, 4289, 4297-4300 (major), 4310-15, 4325-30
