Screening Stocks by Intraday MACD, Amplitude, and Price

Summary

The document proposes a short-term stock screen requiring amplitude above 1, a shrinking negative MACD histogram on a 15-minute chart, and a price below 12. It presents the shrinking histogram as a possible sign of a change in direction and uses the amplitude and price filters to focus on volatile, lower-priced stocks. It also suggests adding market context and fundamental analysis, setting stop losses, and excluding stocks with sharp short-term moves.

The evidence is an outline of the screening rationale and sample formula and Python snippets; it provides no backtest or performance results. The examples do not fully establish a reliable implementation: the amplitude snippet filters turnover ratio rather than high-low amplitude, and the Python example fetches 15-minute data for one named stock before joining it to a broader list. The document also gives no threshold units for amplitude and does not define an exit rule. Treat the criteria as a rough screen requiring data and logic checks, not as a validated trading strategy.

Key ideas

• The proposed screen combines amplitude above 1, a shortening negative MACD histogram on 15-minute bars, and a price below 12.
• The document associates the amplitude filter with volatility and the MACD condition with a possible directional shift.
• It recommends considering market conditions and company fundamentals alongside technical filters.
• It suggests stop losses and avoiding stocks with abrupt short-term price moves as risk controls.
• The sample code may not implement the stated criteria consistently and supplies no performance evidence.
