Pump Dump Screeners

Description

The client needed a system for monitoring market movements, liquidations, and open interest in real-time across a wide range of instruments. Existing screeners lacked the necessary speed, data depth, stability, and filter customization for user trading strategies.

Additionally, a scalable solution was required because the client planned to sell subscriptions to the service and expected a significant number of users. The system had to simultaneously monitor 1000+ assets on Bybit, BingX, Binance, and MEXC with high reliability.

Solution

I developed a comprehensive screener ecosystem that collects, processes, and analyzes exchange data in real-time using asynchronous WebSocket streams with backup REST requests. The architecture ensures high-load handling and stability for a large user base.

The ecosystem includes specialized modules:

• Pump/Dump Detector - detects sudden abnormal price movements and volume spikes;
• Liquidation Screener - tracks liquidations in real-time and notifies of major liquidations;
• Open Interest Screener - records OI increases or decreases, signaling large player activity;

Signals are delivered via a flexible filtering system with Telegram integration, allowing each user to customize their notification settings.

Technical highlights:

• Asynchronous WebSocket processing (hundreds of simultaneous connections);
• Processing queues and pipelines for high-load stability (Kafka);
• Authorization and billing system to sell access to end-users;
• Performance optimization for real-time monitoring of 1000+ instruments.

Result

A fully autonomous, commercially used screener ecosystem was created, monetized by the client via a Django admin panel. Currently, there are 200+ active users, and the service operates without downtime, delivering reliable signals 24/7.

The solution helps traders:

• Track market spikes and abnormal movements in real-time;
• Respond to major liquidations and open interest changes;
• Identify strong impulse assets;
• Receive key analytics signals directly in Telegram.

The system is scalable, does not rely on paid third-party APIs, and provides the client with a reliable foundation for further growth and subscriber increase.
