Instead of one summary bar per minute, every depth update and every print gets its own column, so you can watch a liquidity wall form, see the market orders arrive, and read whether that wall absorbed the flow or broke.",{"q":769,"a":770},"Is a tick DOM heatmap the same as a bookmap chart?","Traders use bookmap as everyday shorthand for this whole category of chart, the same way they say ladder for a DOM or footprint for a volume-by-price cell grid. If you searched for a bookmap chart, a bookmap-style heatmap or a bookmap crypto chart, the chart type you are looking for is a tick-by-tick depth heatmap with a trade tape layered over it — which is what this guide covers. Tape Delta runs it in the browser as the Tick DOM Heatmap chart mode, with no download and no plugin.",{"q":772,"a":773},"What is the difference between a tick DOM heatmap and an orderbook heatmap on candles?","They share a data layer and differ in time resolution. An orderbook heatmap behind candlesticks buckets depth per bar, so it is excellent for mapping walls and liquidity vacuums across hours or days. A tick DOM heatmap buckets depth per update, so it exposes the micro-structure inside a single bar: the refresh rhythm of an iceberg, the exact print that ate a wall, a quote that appeared and vanished before price reached it. Swing and intraday context comes from the candle view; execution timing comes from the tick view.",{"q":775,"a":776},"Do I need a tick DOM heatmap to trade crypto?","No — it is an execution tool, not a requirement. Its value shows up in the last few seconds before you commit: deciding whether a level that looks like support actually has resting size behind it, whether that size is real or being pulled, and whether aggressive flow is being absorbed or is breaking through. Traders who scalp, scale into positions, or care about slippage get the most from it; position traders working off daily structure usually do not need it.",{"q":778,"a":779},"What is absorption on a tick DOM heatmap?","Absorption is when aggressive market orders keep hitting a price level and price does not move, because a passive participant is filling all of it. On the tick canvas it looks like a cluster of trade bubbles stacking against a bright liquidity band that refuses to dim, with price pinned flat. It is one of the few genuinely leading signals in order flow: somebody with size is willing to take the other side here, and the chart shows you the level, the side and roughly how much has been eaten so far.",{"q":781,"a":782},"Can a tick DOM heatmap show spoofing and iceberg orders?","Yes, because both are behaviours over time rather than single snapshots. A quote that appears, sits in the book and disappears without ever being traded against leaves a short bright stripe that stops before price arrives — the classic spoof footprint. An iceberg does the opposite: it keeps getting filled and keeps coming back at the same price, which draws a repeating dotted line in one row. Tape Delta marks both on the chart so you do not have to watch the ladder continuously to catch them.",{},true,"https:\u002F\u002Ftapedelta.com\u002Fblog\u002Ftick\u002Ftick-dom-heatmap-og.png","Tick DOM heatmap on BTCUSDT with size-scaled trade bubbles over live order book liquidity, absorption and spoof markers","\u002Fblog\u002Ftick-dom-heatmap-order-flow-guide","15 min read",{"title":5,"description":761},"Tick DOM Heatmap — Bookmap-Style Chart Guide | Tape Delta","blog\u002Ftick-dom-heatmap-order-flow-guide","ORDER FLOW","oiIF3izLIZIj2yx2gIbvpm1656SrvXR7_bfM505Zf04",[795,796,803,811,818,825,833,842,849,856,862,869,878,884,890,897,905,911,918,924],{"path":787,"title":5,"description":761,"tag":792,"date":760,"readTime":788,"coverImage":43,"coverAlt":759},{"path":715,"title":797,"description":798,"tag":792,"date":799,"readTime":800,"coverImage":801,"coverAlt":802},"What Is Tape Delta?
