Support & Resistance

Support/Resistance Range Finder

Paste a list of recent swing highs and lows (comma or line separated) and set a clustering tolerance to group nearby levels into support and resistance zones. It's the same reason a chart shows a zone instead of one exact price when several swings land close together.

Educational tool only, not financial advice. Clustered zones summarize your own inputted levels, not a guarantee those levels hold. Check it against your own plan and risk rules before you trade it.
