Marks what happens to big order-book walls: eaten, held and refilled, or pulled, right on the heatmap.
In plain English
What it shows
- Markers on big resting walls when something happens to them: a filled square means eaten, a hollow H means held or refilled, a grey x means pulled.
How traders use it
- Study what usually happens when price reaches a big wall.
- Compare eaten, held and pulled walls on the same session.
What it does not tell you
- Pulled versus eaten is worked out from trades at the price, so it is an estimate.
- A marker describes what happened, not what comes next.
Overview
Wall Events (L2) puts a marker on each big resting wall when something happens to it. A filled square means the wall was eaten, a hollow square with H means it held or refilled, and a grey x means it was pulled.
It was built because big walls are often filled by many small orders or pulled, which Big Trades (single aggressive bursts) does not show.
How it works
A wall is either a level that passes the heatmap's colour filter (default) or a level in the top 0.5 % of the session's sizes, and at least 200 contracts or coins. Eaten: at least 50 % of its size traded. Held: at least 50 % traded and price turned away by 4 ticks. Pulled: under 10 % traded while price was within 8 ticks.
How to use it
- Use it to see whether big walls get traded, defended or cancelled.
- Some traders watch for walls pulled as price comes close.
- Use it on top of a DOM heatmap so the markers sit on the bands.
These are ways some traders read it, for learning. They are not trade signals.
