Stock Screening with Price Amplitude, Weekly MACD, and Bollinger Bands

Summary

The document proposes a technical stock screen combining daily price amplitude, weekly MACD conditions, and the closing price's position relative to Bollinger Bands. It describes amplitude above one percent and positive weekly MACD as filters, then presents a Bollinger-based price condition intended to capture a steadier trend. The text also suggests adding fundamental measures and other indicators, such as RSI or KDJ, to broaden the analysis.

The evidence is only a description of the proposed rules and example formulas; no stock list, backtest, benchmark, or performance results are reported. The Bollinger condition is internally inconsistent: the prose says the close should lie between the upper and middle bands, while the formula requires it to be above the upper band and below the middle band, which cannot both hold under the usual band ordering. The accompanying Python example also does not clearly implement the stated weekly MACD filter. The author notes exposure to unexpected events and the limits of relying on Bollinger Bands alone.

Key ideas

• The proposed screen combines price amplitude, weekly MACD, and a Bollinger Band price condition.
• The text recommends considering fundamental factors and additional technical indicators as possible extensions.
• No backtest or measured performance evidence is supplied.
• The prose and formula specify mutually incompatible positions for the close relative to the Bollinger bands.
• The document cautions that unexpected events and indicator limitations can undermine the screen.
