Every row is visible limit liquidity. The tracked bid wall is pinned in view, and its amount bar shows the full 260-unit order waiting below the market.

MNT/USDT liquidity heatmap on Bybit (inverse)
The liquidity heatmap shows the Bybit (inverse) order book for MNT/USDT over time. Time runs left to right, price runs vertically, and color marks how much volume was resting at each level: dark purple means almost nothing, bright yellow means a dense wall of limit orders. The price line is drawn on top, so you can watch how price behaves when it reaches visible liquidity.
Scroll-controlled replay
Bybit (inverse) MNT/USDTChapter 1 / 5 Chapter 2 / 5 Volume becomes one color slice
Price keeps its vertical position while order size becomes color. The tracked wall row maps directly to the brightest cell in the current snapshot.
Chapter 3 / 5 Snapshots accumulate into history
Scrolling adds columns from left to right. The continuous bright band is the same 260-unit wall persisting while the white price line approaches it.
Chapter 4 / 5 Watch the wall get consumed
Resting volume falls from 260 to zero while executed volume rises by the same amount. Because cancelled volume stays at zero in this controlled replay, the fading band represents fills rather than pulled orders.
Remaining in wall: 260 → 0 MNTExecuted into wall: 0 → 260 MNTChapter 5 / 5 Price accelerates through the empty zone
Once the wall is gone, little visible liquidity remains in the gap. Price crosses the dark area quickly and continues toward the next resting wall.
How to read the heatmap
Each horizontal band is a price level. The brighter the band, the more limit orders were resting there at that moment. Levels below the current price are bids, levels above are asks. Bands appear, strengthen, fade and vanish as traders place and cancel orders — the history of that activity is what the heatmap adds over a plain order book.
What the chart is useful for
Three things are easy to spot on the heatmap and hard to spot elsewhere: levels that repeatedly slowed or reversed price, walls that vanish moments before a fast move, and thin dark zones where price travels fast because almost nothing is resting there. The scroll story above demonstrates each pattern.
Quick answers
Liquidity heatmap FAQ
How is this different from the regular order book?
The order book shows resting orders right now. The heatmap keeps the recent history of that depth, so you can see how walls built up, moved or got taken out while price traveled.
Do bright bands mean price will bounce there?
Not necessarily. Price often slows near heavy liquidity, but walls get filled, pulled or ignored all the time. A bright band tells you where orders are resting — nothing more.
Is the data live and how far back does it go?
The chart streams depth from the exchange and keeps a rolling history for the supported time ranges. Network or venue delays of a few seconds are possible.
