Should you buy or should you sell? Options Pro’s proprietary Volatility Range Indicator will take the guesswork out of knowing when to buy or sell single-leg options or spreads. Using a unique study of implied volatility, it quickly identifies whether an option is overpriced or undervalued. If the indicator is high, odds are in the seller’s favor, if the indicator is low, odds favor the buyer. You can even scan for equities that are in the ideal position for your preferred strategy. Brilliant!
