Chinese Stock Screen for High Amplitude, Volume, and Gap-Ups

Summary

This article describes a Chinese equity screen that selects stocks with amplitude above 1, current volume above 10,000 lots, an opening price above the previous close, and an industry classification other than the STAR Market. It presents these conditions as a way to find actively traded stocks with strong opening sentiment. A sample indicator formula and a Python example illustrate how to express parts of the screen using market data.

The article provides no backtest, performance figures, or detailed definition of amplitude. Its Python example appears to check whether every available daily volume clears the threshold, rather than applying the screen only to the latest session, and it does not calculate amplitude. The discussion mentions noise and possible classification errors, and suggests adding technical or fundamental measures. Those suggestions are not evaluated, so the screen should be treated as a selection idea rather than evidence of a profitable strategy.

Key ideas

• The screen combines an amplitude threshold, current volume, an opening gap above the previous close, and exclusion of STAR Market stocks.
• The article frames volume and gap-up conditions as signs of trading activity and positive market sentiment.
• The provided code examples do not fully implement the stated screen in the same way, including the amplitude condition.
• No backtest or performance evidence is reported, and the industry classification may introduce selection errors.
