What is it?

A-Share Quant Selector is a Python system for screening stocks on China's A-share market using akshare for market data. It implements a "bowl rebound" strategy that looks for stocks in an uptrend that recently had a high-volume bullish candle and now sit in an oversold KDJ zone, then sorts them into categories such as price sitting between the short-term trend line and the bull-bear line.

The pipeline covers data download, incremental daily updates, strategy execution, and notification. Each selected stock gets a K-line chart with trend lines and volume bars, and results are pushed to a DingTalk group with built-in rate limiting and retry backoff. Optional B1 pattern matching ranks candidates by similarity to ten historical cases across trend structure, volume, price shape and KDJ state. A Flask web interface lets you browse stock data, charts and indicators, and edit strategy parameters online.

The strategy is defined as a class with a clear base interface, so new strategies can be added by subclassing and registering parameters in YAML. The project is for learning and research, and the README states it does not constitute investment advice.

Key features

  • 01Bowl-rebound strategy filtering on uptrend, high-volume bullish candles and oversold KDJ
  • 02Automatic removal of ST, delisting-risk and abnormal stocks
  • 03K-line charts with trend lines and volume sent to DingTalk
  • 04B1 pattern matching ranks candidates by similarity to historical cases
  • 05Flask web UI for browsing stock data, indicators and strategy parameters
  • 06Strategy parameters configurable in YAML, with a base class for adding new strategies

Use cases

  • Screening A-share stocks daily after market close with scheduled runs
  • Studying a technical-analysis strategy with akshare data and pandas indicators
  • Receiving daily candidate lists and charts in a DingTalk group
  • Tuning strategy parameters and reviewing signals through the web interface
