Fragility bands

Fragility bands answer a simple question: how much money would it take to move price from here? Nocterm walks the live order book and draws concentric bands at the notional tiers you choose - say $10k, $100k, $1M. Tight bands mean a thin book where a modest order moves price; wide bands mean a deep book that absorbs size.

Overview

Section titled “Overview”

Each band marks the price you’d reach if you swept the book with that much notional. When price crosses a band, real size just moved the market that far - useful for sizing your own orders and for spotting moments when the book is thin enough to run.

How to use

Section titled “How to use”

  1. Open Chart Options and switch on Fragility, then choose a tier preset or enter your own.

  2. Read the band spacing. Bands bunched tight to price = a fragile book; bands spread wide = a deep one that will absorb a sweep.
