Mexican peso–U. S. dollars exchange price
This kind of paper gives empirical data that combinations of option implied and time series volatility forecasts that are conditional on current information are statistically superior to person models, absolute, wholehearted combinations, and hybrid predictions. Superior foretelling of performance is achieved by both, taking into account the conditional predicted performance of each and every model given current information, and incorporating individual predictions. The method utilized in this paper to produce conditional combinations stretches the application of conditional predictive potential tests to pick forecast blends. The application is pertaining to volatility forecasts of the Mexican peso–US dollar exchange price, where recognized volatility determined using intraday data is utilized as a serwery proxy for the (latent) daily volatility. © 2012 Elsevier B.

1 . Introduction
Although several designs are trusted by teachers and practitioners to forecast volatility, nowadays there is no general opinion about which method is excellent in terms of predicting accuracy (Andersen et al., 2006; Poon and Granger, 2003; Taylor swift, 2005). The majority of models can be classified in two classes: models based on time series, and models based on options. There are basically two classes of types used in movements forecasting: designs based on period series, and models depending on options (Poon and Granger, 2003). Among the time series models, there are models based on past volatility, such as historic averages of
