(b) acquiring tick data from a data source;
(c) selecting a set of hedging intervals within the period;
(d) selecting a hedging strategy;
(e) selecting an amount of Gamma for a theoretical option position;
(f) iteratively running a simulation at each hedging interval;
(g) calculating a hedging profit or loss at each simulation;
(h) calculating a number of options to enter into a theoretical option position having the selected amount of Gamma;
(i) calculating a premium over parity cost of the options in the theoretical option position;
(j) iteratively adjusting an at-the-money volatility in a selected valuation model until the pop cost for the theoretical position equals the hedging profit or loss; and
(k) setting the intra-period volatility to the at-the-money volatility when the pop cost for the theoretical position equals the hedging profit or loss.

Abstract
Disclosed is a system and method for calculating an intra-period volatility of a security. The system includes a means for collecting tick or selected time interval data from a data source, an interface or storage means for collecting or retrieving assumptions and variables used in the determination, and a processor programmed to perform iterative processes to determine the intra-period volatility and perform uses thereof. The steps of the method include receiving tick or selected time interval data from a data source, retrieving or inputting a set of assumptions for use in the calculations, simulating entering into a spread of options, and iteratively adjusting a variable in a pricing model to produce an intra-period volatility. The method may also include using the intra-period volatility in variety of option-related activities.
