What Problems Does a Listing Screener Solve?
Missing a new token listing on Binance because of manual monitoring of a dozen pages is a lost opportunity to earn hundreds of percent in the first hours. New trading pairs often generate 200 to 500 percent growth, and a delay of just minutes decides whether you get in. This crypto listing screener provides exchange listing monitoring via direct exchange API scraping, ensuring you never miss a new token. We built a screener that tracks new pairs on major exchanges in real time, filters them by given criteria, and sends an alert within seconds. Under the hood are async API requests, websocket subscriptions, and a scoring algorithm to prioritize opportunities.
Automated monitoring is 10 times faster than manual, and the built-in scoring filters out 90 percent of junk listings. Our clients typically save over $10,000 per year in missed opportunities by using our screener. Contact us for an assessment of your project — we will prepare a quote within one day.
How Does the Scoring Algorithm Work?
The algorithm evaluates each new listing by several parameters: exchange weight (Binance: 10 points, OKX: 7, KuCoin: 5), token category (DeFi, AI, RWA: +5), simultaneous listing on multiple exchanges (+8), presence of a futures pair (+5), social activity (Twitter mentions >10,000 in 24 hours: +4), and market cap (below $50 million: +3). The final score ranges from 0 to 30, with grades A, B, C.
| Parameter | Weight | Typical Signal |
|---|---|---|
| Exchange listing | 3-10 | Binance = 10, KuCoin = 5 |
| Token category | +5 | DeFi, AI, RWA |
| Simultaneous listing | +8 | Two or more exchanges |
| Futures presence | +5 | Futures pair |
| Social activity | +4 | Twitter mentions >10,000 |
| Market cap | +3 | Below $50 million |
class ListingScorer: def score(self, listing: NewListing) -> ListingScore: score = 0 signals = [] exchange_weights = {'binance': 10, 'okx': 7, 'bybit': 7, 'kucoin': 5} score += exchange_weights.get(listing.exchange, 3) if listing.category in ['defi', 'ai', 'rwa']: score += 5 signals.append(f"Trending sector: {listing.category}") if listing.simultaneous_exchanges >= 2: score += 8 signals.append(f"Multi-exchange listing: {listing.simultaneous_exchanges} exchanges") if listing.has_futures: score += 5 signals.append("Futures listing included") if listing.twitter_mentions_24h > 10000: score += 4 signals.append(f"High social activity: {listing.twitter_mentions_24h} mentions") if listing.market_cap_usd and listing.market_cap_usd < 50_000_000: score += 3 signals.append("Small cap token") return ListingScore( listing=listing, score=score, signals=signals, grade='A' if score >= 20 else 'B' if score >= 12 else 'C' ) Weights are configurable per user strategy. For scalping, alert speed matters; for swing, fundamental metrics. Our approach flexibly adapts the scoring to your requirements. The listing alert system sends notifications to Telegram instantly, and we offer detailed listing analysis and new token tracking across multiple exchanges.
Why Is It Important to Monitor Multiple Exchanges?
Simultaneous listing on Binance and Bybit is a strong signal: the probability of a pump is higher. The screener polls four exchanges in parallel, detecting such coincidences. Compare delays:
| Exchange | Monitoring Method | Maximum Delay |
|---|---|---|
| Binance | REST + websocket | 1-2 seconds |
| Bybit | REST | 3-5 seconds |
| OKX | REST | 3-5 seconds |
| KuCoin | REST | 5-8 seconds |
For announcements, we also parse news pages — Binance publishes them 1 to 4 hours before trading starts, giving you a critical head start.
How We Monitor DEX and CEX Simultaneously
The screener subscribes to smart contract events on Uniswap and PancakeSwap via a websocket node, catching new pairs before they hit centralized exchanges. This gives access to liquidity hours before the official listing. The algorithm merges data from both ecosystems into a single dashboard.
Project Workflow
- Analysis: Discuss exchanges, notification channels, filter requirements.
- Design: Choose the stack (Python asyncio + React), design the database (Redis + PostgreSQL).
- Implementation: Write the backend (monitoring, parsing, scoring) and frontend with a real-time table.
- Testing: Run on test data, check delays, stress-test.
- Deployment: Deploy to your server (VPS or dedicated), set up uptime monitoring.
What's Included in Turnkey Development
- Documentation: Architectural diagram, filter API description, deployment instructions.

- Deployment: On your server.
- Training: 1 to 2 hour demo.
- Support: 2 weeks after delivery — bug fixes, filter adjustments.
Timelines and Cost
Basic version with monitoring of 4 exchanges and Telegram alerts starts from $5,000 and takes 2 weeks. Extended version (with history, analytics, additional exchanges) up to $12,000 and 4 weeks. Get a consultation — we will estimate the budget and timeline based on your needs.
Common Mistakes When Building a Screener
- Ignoring exchange rate limits — leads to IP blocking. We use backoff and key rotation.
- Lack of websocket reconnect handling. Our code includes automatic reconnection with exponential backoff.
- Storing all historical data in RAM. We use Redis for current state and PostgreSQL for history.
- One-size-fits-all filters — often need customization for different strategies (scalping, swing, long-term).
