Usage
Run the warren command with a stock ticker symbol (as understood by the Yahoo! Finance API):
AAPL: Current 215.05 Low 208.42 High 260.10 Position 12.83% - Buy
This output shows that AAPL's most recent closing price was 215.05, its 90-day low was 208.42, and its 90-day high was 260.10. This puts the current price at 12.83% of its historic range, and it is thus considered a “Buy” (if it were above 50%, it would instead be “Don't buy”).
