Combining Buying Activity, MACD and KDJ for Stock Selection

Summary

This stock-selection idea combines a buying-activity measure with technical signals and recent limit-up performance. The stated screening conditions include a buying-activity ratio above 5%, more than two limit-up days in the prior ten days, and simultaneous bullish indicator crosses. The post interprets the components as signs of capital inflow, upward technical direction, and strong recent performance.

Its final rules describe a DIF/DEA bullish cross with the MACD histogram turning positive, alongside a KDJ bullish cross and a K value above 80. The supplied code reference is internally inconsistent: it does not clearly implement every stated condition, and its KDJ-related variables are drawn from a MACD object. No backtest results or performance evidence are supplied. The author warns that frequent signals may raise trading costs and risk, and that changing market conditions can weaken the signals. Parameter adjustment and adding other factors are suggested, but not evaluated.

Key ideas

• The screen combines buying activity, technical crosses, and recent limit-up frequency.
• The stated technical rules use a bullish DIF/DEA cross, a positive MACD histogram, and KDJ conditions.
• The post gives no performance results to support the selection method.
• Frequent signals can increase costs, and changing market conditions may reduce reliability.
• The code example does not clearly match all of the stated rules.
