A-Share Limit-Up Stock Analyzer

Problem

Stock selection is not just listing what rose; it requires comparing limit-up pools, moving averages, turnover, volume-price structure, and indicator signals in one repeatable review loop. This skill targets A-share main-board screening and answers practical questions: which main-board stocks hit limit-up today, whether their pre-limit structure is healthy, whether sealing orders and volume support continuation, and which names deserve a watchlist.

How It Works

It uses AKShare and stock_zt_pool_em to fetch daily limit-up data. By default it filters out STAR Market 688 names and ChiNext 300/301 names, keeping main-board 60/00 stocks. The workflow then checks:
- Bullish MA structure: compares MA1, MA5, and MA20, and counts consecutive bullish candles before the limit-up.
- Turnover: reads the five trading days before the limit-up and separates active chips, locked chips, and speculative heat.
- Volume-price relationship: flags rising price with rising volume, rising price with shrinking volume, and falling price with rising volume.
- Indicators: uses KDJ, MACD, and Bollinger Bands to detect crossovers, overbought, and oversold conditions.
- Composite score: combines sealing-order ratio, consecutive boards, and limit-up reason into a table, CSV, and charts.
The optional scan action screens all A-share main-board names for limit-up-like features and outputs buy, add, stop-loss, and take-profit levels.

Boundaries

This is a review and research workflow, not investment advice. Data comes from East Money and may be delayed. Non-trading days, network timeouts, and data-source failures return explicit errors. Limit-up stocks can be highly volatile, so validate any strategy on a simulation account first and keep position sizing conservative.
