Exchange halt alerts: know when trading stops or resumes
What is a trading halt?
A trading halt is the moment an exchange stops matching orders for an instrument. On Binance and Bybit every perpetual contract carries a trading status (Bybit's instrument status). When that status leaves "Trading", the book freezes: new orders can't fill, and positions on it can't be traded out there.
The most common halt is not a crash-day freeze but a delisting. When Binance delists a perpetual, the contract moves to SETTLING and the exchange settles open positions; nine Binance perpetuals went that way in the 90 days to 26 September 2026. Less often, a contract is paused for maintenance or a technical problem and then returns to "Trading" — sometimes at a different price than where it stopped.
What Darkmen tracks
The CEX Halt / Resume module reads the trading status of every perpetual contract on Binance and Bybit every two minutes and compares it with the previous read. It fires when a contract's status changes:
- A halt — the contract leaves "Trading": a delisting, a suspension or a pause
- A resume — a contract that had stopped returns to "Trading" and matching restarts
What it does not report:
- New listings. A contract appearing for the first time, or moving from pre-launch to trading, is not a resume.
- A contract that simply disappears from an exchange's list without changing status first.
- A mass flip. If more than a fifth of one exchange's perpetuals change status in a single read, it is treated as a bad API response and nothing is sent — which also means an exchange-wide outage is not reported by this module.
Each alert names the contract, the exchange and the status label the exchange itself uses, so there is no ambiguity about which book changed state and in which direction.
How the alert works
When a status change is read, Darkmen pushes an alert to your connected channels. No watching exchange announcements, no refreshing an order book that may already be frozen.
How to use it:
- Holding a position on a Binance or Bybit perpetual? A halt alert tells you that book has stopped matching; the status label tells you whether it is a delisting (SETTLING on Binance) or a pause.
- Got a resume alert? Matching is back on. A reopened book can print at a different price than the one it froze at, so check your resting orders against it.
- The alert comes when the status actually changes — on Binance, at settlement — not when a delisting is announced. The exchange's own announcement comes first and gives the settlement details.

FAQ
What is a trading halt on a crypto exchange?
A trading halt is when an exchange stops matching orders for an instrument. Every perpetual contract on Binance and Bybit carries a trading status; when it leaves 'Trading', new orders can't fill on that book. The most common reason is a delisting: on Binance a perpetual being delisted moves to SETTLING when the exchange settles it.
Why do exchanges halt and resume trading?
The usual reason is a delisting — the exchange winds the contract down and settles open positions. Exchanges also pause a contract for maintenance, a technical problem or a risk event. When that kind of pause ends, the status returns to 'Trading' and matching restarts, sometimes at a different price.
Why does a halt or resume matter for my positions?
While a contract is halted you cannot add to, cut or exit a position on that book, and a delisted contract is settled by the exchange rather than traded out. A resume can reopen the book at a price gap. Knowing when the status changes means you learn it from an alert instead of from a rejected order.
Which instruments does Darkmen watch for halts?
Every perpetual contract on Binance and Bybit, not a shortlist: on Binance both crypto and TradFi-linked perpetuals, on Bybit including contracts it lists as Closed. The status of each is read every two minutes; a contract that leaves trading status is a halt, and one that returns to trading after stopping is a resume. New listings are not alerted. A delisted contract that the exchange later lists again is a resume, not a new listing.
Which tier includes exchange halt alerts?
CEX Halt / Resume is a Pro module. The alert tells you the contract, the exchange, and the exchange's own status label.
