Stock Screening with Price Amplitude, Volume Ratio, and Weekly Signals
Summary
This stock screen selects for daily price amplitude of at least one percent, a volume ratio between 1.5 and 6 relative to a five-day average, and positive weekly price bars. The article frames the amplitude condition as a way to focus on more active stocks, the bounded volume ratio as a way to find elevated but not extreme trading activity, and the weekly signal as evidence of an upswing. It supplies a formula example and a Python sketch, and suggests adding financial fundamentals, historical evaluation, and industry or sector context.
The article warns that technical filters omit company financial condition and that a weekly rise may be a brief move rather than a durable trend. It gives no backtest results or profitability evidence. The examples also differ: the prose describes weekly positive bars, while the Python sketch adds candlestick-pattern checks and a Friday condition. The screen should therefore be treated as an approximate idea whose rules need clarification and testing, not as a validated strategy.
Key ideas
- The screen combines daily amplitude, a bounded volume ratio, and a weekly positive-price condition.
- The volume ratio compares current activity with a five-day average.
- The article recommends considering fundamentals and sector context alongside technical filters.
- A weekly positive signal may reflect a short-lived move rather than a sustained trend.
- The examples add differing conditions, and no performance evidence is reported.
