A Short-Term Stock Screen Using Amplitude, Recent Gains, and Large-Order Flow

Summary

The article proposes a short-term equity screen based on amplitude above 1, three consecutive prior daily gains that are not limit-up moves, and large-order net inflow during the afternoon. It interprets amplitude as a sign of an active security and afternoon buying flow as a possible indication of demand. The text also advises considering industry and valuation and mentions diversification and additional indicators as possible refinements.

There is no reported backtest or evidence that these signals forecast returns, and the article cautions that a narrow set of indicators can overlook valuation and longer-term fundamentals. The title refers to a three-board streak, while the body describes three consecutive gains that are not limit-up moves, so the intended condition is inconsistent. The sample code uses trading-volume and amount comparisons against rolling averages as proxies; it does not clearly implement the stated afternoon net-flow condition. These details limit reproducibility.

Key ideas

• The proposed screen combines amplitude above 1, three prior consecutive gains, and afternoon large-order net inflow.
• The body specifies gains that are not limit-up moves, despite a conflicting title reference to consecutive limit-ups.
• Suggested refinements include industry and valuation analysis, diversification, and other indicators.
• The example code uses volume and amount surges as proxies and does not clearly measure afternoon net inflow.
• No backtest or performance evidence is provided.
