BTC Order Walls & Large Trades: $83,674.15
**Green bands are buy orders below price; red bands are sell orders above it.**
__Only one live BUY wall and one live SELL wall are labelled.__ Brighter bands contain more money.
**A band stops when the wall disappears.** Hover it to see whether price ate through it or the order was cancelled. *A wall is where money waits now, never a promise.*
A map of the large resting orders around Bitcoin's price, over time. Each band is one wall — a pile of buy or sell orders that stands out of the book (at least $5M, at least 3% of that side, at least five times a typical price step) and stood for at least three minutes — drawn from the minute it appeared to the minute it went away. Green bands are buyers' orders below the price; red bands are sellers' orders above it. The bars on the right are the newest full book: how many dollars are waiting at each price step, up to 5% either side. The candles are the price that resulted. Every clock is UTC.
Read the bands as the levels other traders are watching. A green band under the price is a floor: buyers have parked money there and the price has to eat through it to fall further. A red band above is a ceiling. Brighter means more money. A band that stops was either pulled (the orders were cancelled before the price reached them) or eaten (the price traded through it) — hover it to see which, its size at its biggest and on average, and how long it stood. The 'Right now' line names the closest wall above and below the price with its distance in percent. For example: 'Closest sell wall: $18.4M at $78,120, 0.9% above the price' means the nearest ceiling is a sell pile of $18.4M sitting a little under one percent up. A wall is where orders sit at this moment, not a prediction; large orders are placed and pulled in seconds, sometimes to mislead.
We keep a copy of the whole BTCUSDT perpetual order book in memory, seeded from one snapshot and updated from Binance's live difference stream, resynchronised on any gap. Once a minute we record every price level within 5% of the mid price in steps of 0.05% (about $40 at $77,000) and the largest single levels exactly. A price step (or a run of up to three adjacent steps) becomes a wall when, for three consecutive minutes, its dollar size is at least the largest of $5M, 3% of everything resting on its side, and five times the typical (median) non-empty step — at most the six largest per side each minute; the wall is dated from its first minute. When it holds less than 30% of its peak for two consecutive minutes it ends, marked 'eaten' if the mid price entered or crossed its band during its life and 'pulled' if not. Band opacity follows the wall's peak size on a log scale, capped at the 95th percentile of the walls in view. The ladder's bar lengths follow dollars on a square-root scale. The candles are the same venue's 15-minute klines (1-hour on the 30-day view). The optional heat layer is the older ±0.1% minute photo, painted only for minutes actually photographed; the optional circles are single spot trades of $500,000 or more from our own Binance and Coinbase tape.
Wall history starts the day the book keeper started; Binance publishes the live book only, so nothing before that exists anywhere and this chart never invents it — the stretch before the first minute is hatched and labelled. Iceberg and hidden orders are invisible. Walls are measured on Binance's perpetual contract only; other exchanges can hold walls this chart cannot see. Sizes are what the order book showed, not what will trade: an order can be pulled the second the price approaches it. The 'pulled' and 'eaten' verdicts describe what happened to that pile, not why. The 30-day view keeps 1-hour candles; the heat layer keeps 30 days of photos. The two recordings are different markets and are never blended: the book (walls, ladder, heat) is the PERPETUAL contract, the circles are SPOT trades.
Our own book keeper: the Binance BTCUSDT-perp order book kept live from the exchange's depth stream (seeded from a REST snapshot), recorded once a minute into our own wall and ladder tables; candles from Binance perp klines; the optional heat from our 1-minute depth photos; big trades from our own Binance and Coinbase spot trade streams. Nothing is fetched from CoinGlass or any other heatmap vendor.
Our own recordings: the full Binance BTCUSDT-perp order book kept live from the exchange's order stream (±5% around the price, walls of $5M+ that stand out of the book), plus 1-minute ±0.1% book photos and every Binance and Coinbase spot trade of $500,000 or more
