What is Inverse Head and Shoulders?

Inverse Head and Shoulders is a bullish reversal pattern with three troughs, the middle one lowest, and a neckline joining the peaks. The endpoint returns each trough and peak, the neckline and a projected target.

Inverse Head and Shoulders formula

Output	Calculation
Target	Neckline + (neckline − head)

How to read Inverse Head and Shoulders in your code

Signal	Meaning	Condition
Forming or confirmed	Detection status	`status` and `is_confirmed`
Breakout	Price closed above the neckline	`breakout_occurred` is true
Target	Measured-move projection	`projection_price`

Limitations: Geometric pattern detection depends on pivot settings, so tune deviationATR and depth or lookback values on your own market. A confirmed pattern is not a guaranteed move. Nothing on this page is financial advice.
