How to read it, with examples
How to read it
The signed ratio is (bid quantity - ask quantity) / their sum. Zero means equal quantities; +0.5 means three times as much at the best bid as at the best ask. Negative values favor asks. It uses the last valid quote without smoothing and is absent until one exists.
Constructed example · not historical data
Three at the bid, one at the ask
- Best-quote quantity: 3 bid + 1 ask75% bid share
Separate bid-heavy and ask-heavy snapshots, then compare their recorded outcomes alongside spread and executed taker flow.
What it does not prove
