Screening for Volatile Stocks with Shortening MACD and Recent Limit-Ups

Summary

This stock-selection proposal combines three conditions: amplitude above 1, a shrinking negative MACD histogram on a 15-minute chart, and more than two limit-up days within ten days. The author interprets high amplitude as a sign of volatility, a shortening negative histogram as a possible change in direction, and repeated limit-ups as evidence of market attention. Example formulas and Python snippets outline how these conditions might be combined and how candidates could be sorted by trading amount.

The document cautions that a narrow indicator screen can miss fundamentals and liquidity considerations. Recent limit-ups may also encourage chasing prices and leave market and valuation risks unaddressed. It suggests adding measures such as valuation, profitability, revenue growth, sector activity, and market conditions, while weighing limit-up frequency alongside trading volume and market capitalization. No backtest, trading rules, or measured outcomes are supplied; the snippets leave key computations and data alignment assumptions unresolved, so they should be treated as illustrative rather than validated.

Key ideas

• The proposed screen combines amplitude above 1, a shortening negative 15-minute MACD histogram, and more than two recent limit-up days.
• The author treats these conditions as indicators of volatility, possible momentum change, and market attention.
• The post recommends incorporating fundamentals, sector activity, and broader market risk.
• Frequent limit-ups can encourage chasing, while the examples provide no validated performance evidence.
