The title of this book by Rick Swope and W. Shawn Howell is somewhat misleading. It’s not intuitively obvious, or at least it wasn’t to me, that Trading by Numbers: Scoring Strategies for Every Market (Wiley, 2012) is primarily about options.

But let’s start, as the authors do, with their trend and volatility scoring methods. The trend score has four components: market sentiment (the relationship between a long-term moving average and a short-term moving average and the position of price in relation to each moving average), stock sentiment (the same parameters as market sentiment), single candle structure (body length relative to closing price), and volume (OBV trend). The range is -10 to +10. Volatility scoring has three legs: historical market volatility, historical stock volatility, and expected market volatility. The range is 0 to +10.

Before moving on to the standard option strategies, the authors address risk management, which they wisely describe as nonnegotiable. Risk management again has three legs: risk/reward, concentration check, and position sizing. 

And, with chapter five (of sixteen), we’ve reached covered calls. The reader who has no experience with options will be lost. Even though the authors push all the right buttons (ITM, ATM, OTM strategies; the Greeks; position adjustments), they push the buttons almost as if they were playing a video game. Very fast.

Assuming that the reader is not new to the option market, what can he/she learn from this book? Let’s look very briefly at three strategies and see how they reflect three different market or individual stock conditions: a long call, a straddle/strangle, and an iron condor. Traditionally described, in the simplest of terms, the first is looking for a significant bullish directional move, the second anticipates a surge in volatility, and the third expects a rangebound market.
