HookScreener listens to trades and order books around the clock on 10 crypto exchanges — from Binance and Bybit to Kraken. Our detectors catch large walls, trading-bot activity, liquidity sweeps and price pushing right in the order flow. Every signal we find is published to the terminal in real time, with no delay and no manual moderation.
Large limit orders in the order book — magnets and barriers for price.
How to read it: A buy wall below price acts as support, a sell wall above as resistance. The longer it stands and the closer it sits to price, the more it matters.
Example: A $500k buy wall appears 1% under SOL’s price. Until it’s eaten, pushing price down is hard — traders often place entries just above such walls.

How to read it: A robot pushing price shows force in its direction. One trading against the move is absorbing flow — someone is quietly accumulating.
Example: BTC prints a $2,000 buy every 10 seconds for an hour straight — someone quietly built a $700k+ position.

How to read it: A downside sweep that snaps back often marks a local bottom; an upside one a local top — liquidity on that side is spent.
Example: PEPE drops 3% in one second and gets bought right back. A downside sweep like that often marks the bottom before a bounce.

How to read it: Pushing up: a buyer keeps lifting support higher, propping the price. Pushing down is the mirror — a seller pressing it.
Example: A $30k wall under price gets its first touches — and a new $15k order pops up above it. The buyer is propping price up, expecting a rally.
