CoinPriceNotifier: Real-Time Cryptocurrency Price Alert System

·

Cryptocurrency markets never sleep — and neither should your price monitoring strategy. With rapid price swings occurring in minutes, staying ahead of market movements is crucial for traders and investors alike. Enter CoinPriceNotifier, an open-source tool designed to deliver real-time alerts when digital asset prices cross user-defined thresholds. Built for simplicity and efficiency, this lightweight application supports multiple platforms and leverages SMS notifications to keep you informed — anytime, anywhere.

Whether you're tracking Bitcoin’s next breakout or watching Ethereum for a sudden dip, CoinPriceNotifier ensures you don’t miss a critical market moment.

How CoinPriceNotifier Works

At its core, CoinPriceNotifier continuously monitors cryptocurrency prices across major exchanges using live market data. The system compares current prices against user-set thresholds — both upward (gains) and downward (losses). When a price exceeds the specified percentage change, the tool triggers an instant SMS alert to your mobile device.

This automated monitoring eliminates the need for constant screen-watching, making it ideal for busy traders, long-term holders, or anyone who wants timely updates without manual tracking.

Cross-Platform Compatibility

One of the standout features of CoinPriceNotifier is its broad platform support. Designed to be lightweight and dependency-free, it runs seamlessly across various operating systems and embedded devices:

No compilation is required, which means you can deploy it quickly on almost any device with minimal setup. This flexibility makes it perfect for running 24/7 on low-power hardware like a Raspberry Pi at home or a cloud-based Linux instance.

SMS Notification System

Timely alerts are only useful if they reach you instantly — that’s where the integrated SMS service comes in. CoinPriceNotifier uses Alibaba Cloud’s SMS Gateway to send text message notifications directly to your phone.

Each message costs just 0.045 CNY, offering a cost-effective way to stay updated without relying on internet-connected apps or push notifications that may be delayed or blocked.

To configure the service, users provide their Alibaba Cloud credentials, including:

Once set up, the system automatically sends SMS alerts whenever a monitored cryptocurrency hits your predefined price movement thresholds.

Reliable Data Source Integration

Accurate alerts depend on accurate data. CoinPriceNotifier pulls real-time cryptocurrency pricing from Feixiaohao (also known as Non-Small Number), a well-known Chinese platform that aggregates price data from multiple exchanges.

By sourcing data from a trusted aggregator, the tool ensures reliable and consistent price feeds for a wide range of digital assets.
