CEX Halt / Resume

What it is

Any Binance and Bybit perpetual contract changes trading status — halting (leaving "Trading": a delisting, a suspension or a pause) or resuming (a contract that had stopped returns to trading). New listings do not count.

Why it matters

A halt stops matching — no new orders fill, and positions on that book can't be closed or adjusted there. When a contract is delisted, the exchange settles every position still on the book. A resume can reopen at a sharply different price than where trading stopped.

How to read the alert

The alert carries the exchange's own status label — on Binance a perpetual being delisted shows SETTLING — and the moment the change was read. It fires when the status actually changes — on Binance, at settlement — not when a delisting is announced. While an instrument is halted its book is frozen: resting orders cannot fill and new ones cannot be placed on that venue. A resume means matching has restarted, and the first prints after it are the market's first chance to reprice whatever happened during the freeze.
