A Chinese Equity Screen Combining Amplitude, Control, and a Candlestick Signal

Summary

This post describes a short-term stock selection screen that combines a daily amplitude threshold, a condition labeled as main-force control on the prior day, and a Morning Star candlestick signal on the current day. It presents the combination as a way to find stocks that may offer short-term opportunities and includes references to indicator formulas and a Python example for selecting candidates from market data.

The post’s explanation of the candlestick signal is internally inconsistent: it calls the pattern a reversal signal but says it may indicate the end of an uptrend and increased downside risk, rather than clearly defining the intended trade direction. It provides no backtest, performance results, precise validation of the control measure, or detailed entry and exit rules. The author warns that the signal can be wrong and that short-term trading carries elevated risk, recommending risk controls and consideration of fundamentals, valuation, and broader market conditions. The screen is therefore an illustrative filter, not evidence of a reliable strategy.

Key ideas

• The proposed screen combines amplitude, a prior-day control condition, and a current-day Morning Star pattern.
• The post frames the selection logic as a short-term equity screening method.
• Its description of the candlestick signal and expected direction is inconsistent.
• No performance evidence or complete rules for entries and exits are provided.
• The author notes signal error and short-term trading risk, and suggests broader analysis and risk controls.
