Binance Monitoring Tag Alert

A real-time alert for every change to Binance's Monitoring Tag — the risk label that flags a token for possible delisting. When Binance extends the tag to a token or removes it, our WebSocket pushes a structured JSON event with the affected tickers and microsecond timestamps. The tag going on is a warning; the tag coming off is often a positive technical signal. Either way, it is a discrete, dateable event your bot can trade.

What is the Monitoring Tag?

The Monitoring Tag is a risk designation Binance attaches to tokens that show higher volatility or drift below its listing standards. Tagged tokens sit in a monitoring zone: Binance reviews them regularly, warns users of elevated risk, and can remove them from the platform if they keep failing the criteria. Importantly, the tag is a risk label, not an automatic delisting — a token can carry it for a long time, and many eventually have it lifted once they recover.

Because Binance is the largest venue by volume, its risk labels carry weight far beyond its own order book. When a token is placed under the Monitoring Tag, the market reads it as a raised probability of delisting; when the tag is removed, it reads as a return to good standing.

Monitoring Tag vs Seed Tag

Binance runs two related risk labels, and they are easy to confuse:

Both live in the same family of "handle with care" designations, but the Seed Tag is about a token being young, while the Monitoring Tag is about a token being watched. Binance sometimes moves both in a single press release — for example removing the Monitoring Tag from one token while removing the Seed Tag from several others in the same notice.

Why the tag change is a signal

A Monitoring Tag change is one of the cleaner event-driven signals on Binance precisely because it is published, discrete and dated. There is no ambiguity about when it happened — it is an official announcement.

• Tag added (monitoring_tag_extend) — Binance is flagging elevated risk and a raised chance of eventual delisting. Historically this has coincided with selling pressure on the affected tokens.
• Tag removed (monitoring_tag_remove) — the token has returned to compliance and left the monitoring zone. This is frequently read as a positive technical event.

For a risk desk, the "added" event is a reason to reassess exposure the instant it lands. For a discretionary or systematic trader, the "removed" event is a candidate long trigger. Either way, being early depends on hearing the announcement as it publishes, not on noticing the label change on the token's page later.

How the alert works

CryptoListing.ws watches Binance's official announcement channel and broadcasts a structured JSON event the instant the Monitoring Tag is extended or removed. Your bot holds one persistent WebSocket connection and receives each change as a push — there is nothing to scrape on your side.

Extend events often arrive in batches — Binance frequently flags 5 to 10 tokens in a single notice, delivered as one event with a comma-separated ticker field. Remove events are usually narrower, often one token at a time. When a single press release both extends and removes the tag, the feed splits it into two distinct events with disjoint ticker lists, so you can react to each side independently.

Connect and filter for Monitoring Tag changes

# pip install "websockets>=14"  — header param is additional_headers
# (extra_headers was removed in websockets v14+)
import asyncio, json, websockets

API_KEY = "dsk_your_key_here"
WS_URL  = "wss://cryptolisting.ws?cex=binance"

async def run():
    headers = {"X-API-Key": API_KEY}
    async with websockets.connect(WS_URL, additional_headers=headers) as ws:
        async for raw in ws:
            msg = json.loads(raw)
            if msg.get("type") != "announcement":
                continue
            lt = msg["listingType"]
            if lt == "monitoring_tag_extend":
                flag_risk(msg["ticker"].split(","))   # tag added
            elif lt == "monitoring_tag_remove":
                clear_risk(msg["ticker"].split(","))  # tag lifted

asyncio.run(run())

Message format

A typical monitoring_tag_extend event — note the comma-separated ticker when several tokens are flagged at once:

{
  "type": "announcement",
  "title": "Binance Will Extend the Monitoring Tag to Include NFP, NOM, POND, QUICK & VIC",
  "ticker": "NFP,NOM,POND,QUICK,VIC",
  "publisher": "binance",
  "listingType": "monitoring_tag_extend",
  "detectedTimestampUs": 1745971200834000,
  "dispatchTimestampUs": 1745971200842117,
  "abnormalDetectionLatency": false
}

When a notice mixes the Monitoring Tag with Seed Tag changes, a monitoring_tag_* event lists the Monitoring Tag tickers only; Seed-Tag-only tickers in the same announcement are excluded and Seed-Tag-only notices arrive as not_listing. This keeps the two risk programs cleanly separable in your handler.

FAQ

What is the Binance Monitoring Tag?

A risk label Binance attaches to tokens with higher volatility or elevated risk versus its listing standards. Tagged tokens sit in a monitoring zone, are reviewed regularly, and can be delisted if they keep failing the criteria. It is a public risk signal, not an automatic delisting.

How is the Seed Tag different?

The Seed Tag marks newer, early-stage tokens that are volatile by nature; the Monitoring Tag marks tokens under review for possible delisting. Both are risk labels, but Seed is "young" and Monitoring is "watched". Binance sometimes changes both in one announcement.

Which events does the feed emit?

Two: monitoring_tag_extend when the tag is added, and monitoring_tag_remove when it is lifted. Both arrive on the same WebSocket connection as listings, delistings and airdrops — branch on listingType.

How often do these fire?

Historically around one to two announcements per month, with extend events often batching several tokens and remove events usually narrower. Reconnecting subscribers can deduplicate cleanly by keying on the (publisher, listingType, ticker, detectedTimestampUs) combination each event carries.
