| | Standard-Deviation Technicals |
 | | Standard deviations are a natural fit for the financial markets, as they are effectively a measure of volatility, which in and of itself is one of the primary variables that speculators zealously watch. |
 | | The deviation part refers to the volatility of data away from its average, while the standard part refers to the notion that a known percentage of any dataset is always within defined multiples of a “standard” deviation. |
 | | Standard deviations quantify core market volatility in a unique, comparable, and easy to understand way that no other indicator can touch, including the mighty VIX implied volatility index. |
