Selecting Stocks by Trading Range, Main-Force Control, and Limit-Ups

Summary

The strategy screens Chinese stocks for a daily amplitude above 1, evidence of main-force control on the previous day, and at least two limit-up sessions during the prior 500 days. The post presents these conditions as a way to find stocks with potential for short-term gains. Its sample Python implementation adds filters involving trading activity, valuation, market capitalization, shareholder data, and special-treatment status, then checks historical ticks for limit-up moves.

The document offers no backtest results or measured performance. It warns that a technical screen can omit fundamental information, that the historical limit-up requirement may leave too few candidates, and that price behavior can diverge from technical expectations. It suggests treating the limit-up condition as optional and incorporating fundamentals and industry trends. The sample code is illustrative and does not fully match the stated screening logic, so its results should not be assumed to implement the described strategy exactly.

Key ideas

• The stated screen combines daily amplitude, prior-day main-force control, and repeated limit-up sessions over a 500-day lookback.
• The sample code includes additional activity, valuation, capitalization, and shareholder filters.
• The post gives no performance evidence or backtest results.
• The author identifies reliance on technical criteria and sparse candidate counts as risks.
• Adding fundamental and industry information is suggested as a way to broaden the screen.
