Stock Monitor: A-share Stock Alerts with US Market and ETF Support
Introduction
Stock Monitor is a C++ service I built that can be deployed as an online web service to monitor technical indicators — such as MACD golden crosses — on A-share stocks and ETFs, firing off an email alert when a threshold is triggered.
Written in C++, it has a tiny memory footprint and sips server resources, keeping hosting costs down.
- Beyond individual stocks, it also monitors on-exchange ETFs. As most traders know, ETFs have lower trading costs and let you avoid single-name risk.
- Indicator monitoring is parameterized — MACD periods, for example, are fully customizable.
Key technical components:
- Multi-source data fallback;
- A-share and US market support; stocks and ETFs;
- HTTP networking;
- K-line parsing and technical indicator computation with configurable parameters;
- Trading-day and trading-hours detection;
- Email delivery;
- Production web deployment: authentication, firewall, hardening.
I’m running it for my own use. Due to certain constraints I can’t offer it as a public service — you’ll need to deploy the software yourself.
