Every large resting order (“wall”) within 2% of price on Binance BTC and ETH perpetuals, tracked from the raw L2 feed by our own collector. When a wall disappears we record how: eaten by real trades, or pulled before price ever reached it. Public order books carry no identity, so this page shows behavior, never intent — a pulled wall is a fact, “spoofing” is a verdict only a regulator can issue.
The folklore says big walls are “support” and “resistance.” The lifecycle data lets you check: a wall that is consumed was real liquidity someone paid to provide; a wall that is pulled the moment price approaches was theater. We classify a death as consumed only when at least half the wall's peak size traded at or through its level while it stood.
Two honest caveats. First, most walls never meet price at all — the market moves away and the order is cancelled for boring reasons; a high pull rate alone does not prove manipulation. Second, iceberg orders and order splitting mean the visible book understates real intent in both directions. That is why this page reports behavior counts, not accusations.
We built this collector because order-flow signals — book imbalance, wall behavior, funding, open interest — are inputs our Lumen data layer tracks continuously. Once Wall Watch has enough history, wall-pull asymmetry becomes a gradeable entry signal like any other: it will have to prove itself out-of-sample, same as everything else.
The same market-data engine behind this page also captures every forced-liquidation event on Bybit USDT perpetuals, tick-level — 36,050 events and counting across nine assets, refreshed weekly, free re-downloads forever.
