Live listings and delistings UTC

From each exchange's own public market list: the spot and perpetual USDT markets Binance, Bybit, OKX, Bitget, Gate, MEXC, KuCoin and Bitunix publish. About every 30 minutes the lists are read again and compared with the last read. A market that was not there before is a new listing; a market that disappears is a delisting. Announcement pages add the notices, the stated dates and the Binance monitoring tags.

Some exchanges state the opening time in their market list; then that time is shown. Where they do not, the time is when the market first appeared on the list, which can be up to about half an hour after it really opened. It is never moved earlier to look faster.

From the listing exchange's own public hourly candles: the open of the first hourly candle after the listing is the start price, and the change is read 1 hour, 24 hours, about 7, 30 and 180 days later. A listing is measured only once that time has passed; before that the cell says so. Nothing is estimated or backfilled.

Binance marks tokens it is reviewing with a monitoring tag and says so in a notice. Tagged tokens can be delisted later, but a tag is not a delisting. The watchlist shows when each token was first named and whether a delisting notice followed.

KCEX does not publish a market list that can be read without an account, so nothing about it would be measured. Rather than guess, it is left out until such a list exists.

The market lists are read about every 30 minutes and the notices about every hour, so an alert can come up to that long after the exchange's own change. For a launch with an announced time, the countdown runs from the moment the market or notice is read.
