This indicator provides possible short, medium, and long-term support and resistance levels based on recent highs and lows. The furthest the level is, the thicker its line is, making it easy to spot stronger levels where 2 lines overlap. It can be configured to use open/close values instead of high/low for tighter levels.
Default settings:
- Short Period: 20
- Medium Period: 50
- Long Period: 100
This script also provides alerts for when the price crosses over/under a given level or pulls back.
Note: It sometimes displays supports above the price and resistances below it, I still have to figure out why (and fix it if possible), but it's still useful.
