Screening for A-Shares with Tight Moving-Average Clusters

Summary

This proposed stock screen looks for shares with at least five moving averages clustered together, evidence of main-force control on the previous day, and a pre-open gain below 6% at 9:25. The rationale is that clustered averages may mark a potential turning point or an area of support or resistance, while the control condition is treated as a sign of capital interest. A modest pre-open gain is interpreted as possibly reflecting a pullback or shakeout. The article later revises the screen to at least three clustered averages and suggests buying after 9:25.

No backtest, return data, or operational definition of moving-average proximity or main-force control is supplied. The text itself notes that clustering does not establish that an uptrend will persist and that a pre-open screen can miss opportunities. Its Python example is incomplete: it calculates several averages for a single quoted security but does not implement the stated clustering test or show the other filters. The proposal is therefore not a fully specified or verified strategy.

Key ideas

• The original screen requires five clustered moving averages, prior-day main-force control, and a 9:25 gain below 6%.
• The proposed rationale treats average clustering as a possible turning point or support and resistance area.
• The article later suggests relaxing the cluster requirement to three averages and buying after 9:25.
• It provides no performance evidence or precise definitions for clustering and main-force control.
• The sample code does not complete the described selection logic.
