A Chinese Stock Screen Using Amplitude, Weekly MACD, Volume, and Gap-Up

Summary

This post describes a Chinese equity screen that combines daily amplitude above a threshold, a positive weekly MACD signal, current trading volume above a stated level, and an opening price above the prior close. It presents the conditions as a way to find volatile stocks with an upward technical signal, active trading, and a gap-up open. It also provides example implementations in a charting formula and Python, along with instructions for placing a selection statement into a backtesting template.

The post does not report backtest results or establish that the screen predicts returns. It warns that the approach relies heavily on technical measures, that volume and gap-up conditions may add risk, and that opening prices are influenced by uncertain market sentiment. It suggests adding fundamental filters and risk controls against excessive concentration. The code is illustrative and may require adjustment to a user's data and platform conventions.

Key ideas

• The screen requires amplitude above a threshold and a positive weekly MACD reading.
• It also requires current volume above a stated level and an open above the previous close.
• The post gives example implementations for a charting formula and Python.
• It cautions that technical filters and gap-up behavior carry uncertainty and concentration risk.
• The author suggests adding fundamental filters and risk controls, but supplies no performance evidence.
