Use the depth heatmap to place your levels where liquidity actually sits.

Support and resistance drawn from candles is opinion. The depth heatmap is measurement: it plots the resting limit orders in the book, level by level, snapshot after snapshot. Bright horizontal bands are walls of liquidity; when they hold, price bounces, and when they vanish just before price arrives, someone never intended to be filled. This tutorial explains how to read the bands and turn them into entries and stops.
Walls, magnets and pulled liquidity
A persistent bright band is a wall: real size waiting. Price often approaches it, consumes part of it, and reacts. A band that appears and disappears repeatedly as price approaches is likely spoofing — treat it as noise, not support. And large liquidity just beyond a round number frequently acts as a magnet: price gets pulled toward size before reacting.
From bands to trades
Entries: fade a tested wall (buy in front of a strong bid band) with a stop just behind it — if the wall gets eaten, your reason for the trade is gone, exit. Targets: the next visible band, because that is where the market found interest before. Avoid entering in the empty zones between bands; with no resting liquidity, price moves fast and slippage is worst there.
Check it live in Optiom
Open the Heatmap terminal in depth mode (signed-in account required). The order book collector snapshots the book roughly every 2 seconds, so the map builds from the moment collection started — there is no retroactive book history, which is true of every depth product on the market. The same matrix is available raw from the /depth API endpoint for your own analysis.
