A-Share Reversal Screen Using RSI, Seven Down Days, and Weekly Bars

Summary

This proposed A-share screen looks for stocks with RSI below 65, seven consecutive down sessions, and a positive weekly chart-bar condition. The post frames the setup as a possible way to find shares that have declined for an extended short period while showing a weekly signal interpreted as potential support or reversal. It gives indicator definitions and a code example, including a 14-period RSI and a weekly-bar condition, but does not report a backtest, trades, or observed results.

The author cautions that technical filters cannot reliably predict price changes and says the weekly red-bar condition needs further validation. It also identifies liquidity and the absence of fundamental or industry analysis as concerns, suggesting that turnover, other technical indicators, and company or sector information could be considered. Some of the explanatory claims about a bottom and controlled risk are not supported by evidence in the document. The screen is therefore a hypothesis for further testing, not an established reversal strategy.

Key ideas

• The screen combines RSI below 65 with seven consecutive declining sessions.
• It also requires a positive weekly bar condition intended to indicate a possible reversal.
• The post provides no backtest or reported trading results.
• It flags indicator reliability and liquidity as limitations.
• The weekly signal and the reversal interpretation require validation.
