Stock Screening with Weekly Moving-Average Cross, Amplitude, and Volume
Summary
This post describes a short-term stock screen combining price amplitude above 1%, a weekly five-period moving average crossing above a ten-period average, current volume above 10,000 lots, and an opening price above the previous close. It presents the mix as a way to consider volatility, trend, and trading activity together. The article includes formulas and sample code, but supplies no backtest, performance statistics, or examples demonstrating that the conditions predict returns.
The author warns that gap openings can reflect transient market sentiment and lead to sharp price fluctuations, while reliance on a small set of technical measures leaves other market influences unaddressed. RSI and additional trend indicators are suggested as possible checks. The code also contains discrepancies: it uses daily rolling averages rather than clearly calculating weekly averages, and some opening-price comparisons are framed differently from the prose. Data frequency, signal timing, and the exact gap condition should be clarified before research use.
Key ideas
- The screen combines price amplitude above 1% with a moving-average crossover.\nIt requires current volume above 10,000 lots and an opening price above the prior close.\nThe post identifies gap-related volatility and reliance on technical signals as risks.\nIts sample code does not clearly implement the stated weekly averaging period, and no results are reported.
