Stock Screening with High Amplitude, Trading Volume, Gaps, and Institutional Activity

Summary

This note presents a stock screen based on amplitude above 1, current volume above 10,000 lots, an open above the previous close, and positive institutional activity. It interprets high amplitude and volume as signs of active trading, a higher open as a directional clue, and institutional activity as a possible indication of large-investor demand. The document includes a formula and sample code, but the code also applies a long moving-average condition and holder data, so it does not precisely mirror the stated screen.

The note provides no performance results or testing evidence. It warns that relying heavily on technical and flow-related measures can overlook company fundamentals and broader market or sector conditions. It recommends combining price indicators with valuation and profitability measures, and accounting for policy, industry, and market risks. The criteria are a starting point for candidate selection, not evidence that the selected shares will continue upward.

Key ideas

• The screen looks for amplitude above 1, volume above 10,000 lots, a gap up, and positive institutional activity.
• It treats volume, price movement, and institutional flows as signs of activity and potential demand.
• The sample code adds conditions that are not identical to the stated selection logic.
• The note offers no evidence that the signals produce positive returns.
• It recommends adding fundamental measures and considering sector, policy, and market risks.
