What is Support & Resistance?

This endpoint detects horizontal support and resistance lines from price pivots, merges nearby levels and keeps those touched enough times. Each line comes with its type, price and the timestamps it spans.

Support & Resistance formula

Output	Calculation
Pivots	Swing points confirmed by `lookback` and `lookforward`, and filtered by ATR deviation
Lines	Pivots within `merge_distance` grouped into levels with at least `min_touches` touches

How to read Support & Resistance in your code

Signal	Meaning	Condition
Type	Support or resistance	`line_type`
Level	Line price	`price`
Span	When the level was active	`left_timestamp` to `right_timestamp`

Limitations: Pivots need lookforward candles to confirm, so the newest structure appears with a delay. Nothing on this page is financial advice.
