Intraday Stock Screening with Shrinking MACD Bars and Rising Prices

Summary

This Chinese-language article describes a stock screen combining amplitude above 1, a 15-minute MACD histogram below zero but shortening, and a price rise over four periods as a sign of an upward move starting. It gives indicator-formula examples and a Python illustration intended to show how the conditions could be combined. The stated approach seeks shares with notable price movement and improving short-term technical conditions.

The article cautions that the screen ignores fundamentals and can select stocks exposed to adverse news or other risks; it recommends considering market direction, fundamentals, volume and price, and risk controls. It provides no backtest, trade rules, transaction-cost analysis, or performance results. Some example implementation details appear inconsistent with the stated conditions: the amplitude example uses turnover ratio, and the code’s MACD calculation and price comparison require careful interpretation. The screen is therefore an illustrative technical filter, not evidence of a validated trading strategy.

Key ideas

• The screen combines amplitude, a contracting negative MACD reading on a 15-minute interval, and a recent price rise.
• The article presents formula and code examples to illustrate combining the filters.
• It warns that technical-only selection can overlook fundamentals and adverse news.
• The author suggests considering market conditions, fundamentals, volume-price data, and risk controls.
• No performance evidence is supplied, and the examples contain implementation details that warrant verification.
