Chinese Stock Screen Using Rising Lows and Bid–Ask Volume

Summary

The document describes a Chinese equities screening idea that selects stocks with price amplitude above a stated threshold, rising lows, and first-level bid volume greater than first-level ask volume. It interprets the price conditions as a way to find relatively steady charts and the bid–ask volume comparison as a liquidity-related filter. The article also lists possible additions, including volume, turnover value, and other technical indicators.

Its proposed rule set includes trend and Bollinger-band conditions, with an exit when a bar or closing price falls below the Bollinger middle band. The page supplies example formulas and Python-like implementation guidance, though some details appear inconsistent: the stated exit rule differs from the sample sell-signal conditions, and the code uses additional indicator conditions. The document provides no backtest, return figures, or validation of the claimed screening rationale. It cautions that the simple filters may miss candidates and may fare poorly during broad market declines or volatility.

Key ideas

• The screen combines price amplitude, rising lows, and first-level bid volume exceeding ask volume.
• The article suggests adding volume, turnover value, or further technical indicators to refine selection.
• Its stated exit condition is a break below the Bollinger middle band.
• The provided code includes conditions that do not fully match the prose rule description.
• No backtest or measured performance is reported.
