Intra-day Volatility Pattern

When we speak about volatility we generally refer to the relative movement of an instrument, say stock, from its center, say average. So high volatility instrument means high swings in its price process. In recent years, with the increase in “fire power”, both in computing and information flow, there has been a spike in analysis of intra-day data. Data that describes the price within the day, as oppose to the more conventional, “open” (open price of the stock for the day) and “close” quotes.

We take a look at the pattern of “swings” from stock prices within the day.
