Screening Stocks with Positive MACD and a Prior Limit-Down Match

Summary

The post describes a premarket stock screen combining a positive MACD reading, a price below the stated threshold, and a prior-day 9:15 matching price at the limit-down level. It frames the conditions as a way to combine a technical signal, a low share price, and an unusual prior trading event. The article also sketches indicator formulas and a Python example, though the example contains references to data and fields that are not fully defined.

No backtest, sample, or performance evidence is presented. The post itself cautions that the screen may over-rely on a single prior-session event and that unusual price behavior can make the signal unreliable across different market periods. It suggests supplementing the conditions with additional technical and fundamental measures, but does not specify a tested refinement. The screen is therefore a strategy concept rather than a validated trading method.

Key ideas

• The screen combines positive MACD, a share-price ceiling, and a prior-day limit-down matching event.
• It is intended to run before the market opens.
• The article gives formula and code sketches, but some referenced data fields are unspecified.
• The post warns that dependence on one unusual prior-session condition can produce unreliable selections.
• No backtest or evidence of profitability is provided.
