A pane with trade delta and book delta for every bar, stacked, plus a pulled versus added readout.
In plain English
What it shows
- A pane with two numbers per bar. Trade delta is volume bought at the ask minus volume sold at the bid. Book delta is the size added or removed on the bid and the ask.
- Together they show what traded and how resting orders changed.
How traders use it
- Compare delta with the candle: did price move the way the delta pointed?
- Look for bars where trade delta and book delta disagree.
What it does not tell you
- Delta describes one bar and can flip the next.
- Resting orders can be pulled at any time, so book delta is a snapshot of intent, not a commitment.
Overview
Delta (L2) shows two kinds of delta per bar in its own pane. Trade delta is buying minus selling volume. Book delta is how much resting size was added or removed on the bid and the ask.
Together they show what traded and how the book changed in the same bar.
How it works
Trades are split into buys and sells by the side they hit. Book delta compares the resting size in the 10 rows nearest price (by default) at the start and end of each bar. It also adds a price-axis ladder when it starts.
How to use it
- Use it to see whether size was being added or pulled while trades went through.
- Some traders watch bars with strong buying but the ask side still growing.
These are ways some traders read it, for learning. They are not trade signals.
