What is a large order pull?
A large order pull occurs when unusually big resting orders appear near the best bid or ask and are quickly cancelled before they can be filled. This changes the visual shape of the book and can mislead participants about true available liquidity.
Why it matters for execution
When large displayed orders vanish, traders who relied on that apparent support or resistance can be forced to reprice quickly. Slippage rises because the depth they expected to trade against is no longer there.
How to read the signal
An isolated pull can be normal risk management. Repeated large pulls clustered around price moves are more suspicious. The signal is most informative when combined with fake support/resistance or momentum ignition behavior.
