It is well known that high-frequency asset returns are fat-tailed relative to the Gaussian distribution tails are typically reduced but not eliminated when returns are standardized by volatilities estimated from popular models such as GARCH. We consider two major dollar exchange rates, and we...

We propose using the price range, a recently-neglected volatility proxy with a long histoy in finance, in the … estimation of stochastic volatility models. We show both theoretically and empirically that the log range is approximately … Gaussian, in sharp contrast to popular volatility proxies, such as log absolute or squared returns. Hence Gaussian quasi …
