Selecting Stocks by Intraday Range, Auction Value, and a Rounded Base

Summary

This Chinese stock-screening post describes selecting shares with an amplitude above 1, ranking them by the day’s auction amount, and retaining the top five that show a rounded-base pattern. It interprets the pattern as a possible precursor to an upward breakout and uses the amplitude filter to favor more active stocks. The post suggests combining these technical conditions to identify candidates, but it does not define the rounded-base indicator or explain precisely how auction amount is ranked.

The article offers no backtest, performance figures, or detailed evidence that the screen predicts returns. Its sample code is explicitly illustrative and contains placeholders for both the ranking and pattern conditions; it also uses a turnover field and threshold that do not clearly match the stated amplitude rule. The author notes that technical patterns can be disrupted by unexpected events and that the screen omits financial fundamentals. Suggested refinements include adding other technical indicators and screening valuation or dividend measures, but no validation of those additions is provided.

Key ideas

• The screen combines an amplitude threshold, a top-five auction-amount ranking, and a rounded-base pattern.
• The post treats a rounded base as a possible signal of an upward breakout, without defining its detection rule.
• The sample code is illustrative and leaves key ranking and pattern logic unspecified.
• The author cautions that technical-only screening can overlook fundamentals and unexpected events.
