 ====Volatility Index====

+**Premise**: //volatility indices represent the implied volatility mediated by a series of options on different maturities. There are indices in which the implied volatility they represent is that

+rolling, ie the volatility of series of options that also imply different deadlines but not exceeding 30 days. \\
+For example, on the first day of the year, the index will only represent the implied in January while on January 15 the implied we will read will be the average of options that have 15 days of life on January and 15 days of life on February. \\
-The known Volatility index inform when volatity goes up or down, conversely  the volatility index built in Iceberg show whether is priced an up trend or a down trend!  \\
+As you see it will always be 30 days. \\
-This is more and more useful than the standard index! \\
+Other types of calculation always represent implied volatility of options but grouped in different ways. \\ //
-For example if we put the crosshair on 10/11/2015, the index price a probably down trend. After we see that it happen! \\
 \\
-If the index is above the zero it prices a down trend while the index is below the zero it prices an uptrend.
+We devised this algorithm because it lacked a Volatility Index that not only implied the implied volatility that I already find in the other indices, but give an indication (Index) of the probable trajectory of the underlying.
-The Iceberg's volatility index is an interpolation of implied volatility but it are not the midpoint of weighted volatility. It is different from VIX or VDAX o VSTOXX. It reflect the trend priced by Market Maker\\
+We have extended it to all the financial instruments and you can find it on actions, currencies, futures and bonds. \\
 \\
-For example during fall in volatility, the index can rise, this is due to the fact that the "conviction" of an uptrend is decreasing
+***Using***: Iceberg's Volatility Index is used both to evaluate the trend and to determine the time of upswing or downturn of volatility. There are two viewing modes that are: \\

-The value expressed by classic index can be obtained through the mean of the implied volatility of the three option  "approximately" ATM measured on 30 days rolling.

-on 1 March: there's only the volatility of March expiry\\
-on 15 March: there's the volatility of March expiry + April expiry volatility divided by 2\\
-on 29 March: there's the March expiry volatility divided by 30and multiplied by 1, + the April expiry volatility divided by 30 and multiplied by 29.\\

 ===Difference===
-Iceberg compares the historical volatility and the implied volatility calculated by the system [[market_maker_surfaces|Market Maker Surfaces]]. This difference is shown on the lower graph.\\
+This mode allows to estimate the difference between the Volatility Index and historical stock volatility relative to 30,50,75,100,150 periods such as the difference between each historical volatility and another of a different period.\\
 \\
-Every volatility can be selected or deselected by clicking on the name at the top.
+Analyzing with the Volatility Index is important to determine if Market Maker is pricing (implied volatility) greater or lesser than historical volatility and therefore you know whether you will be handling discount or bonus options.\\
+\\
-The chart below is designed for comparing different historical volatility. When you click the Difference button the next menu is enabled which allows you to choose which historical volatility comparison with those seen in the top graph.
+The analysis of historical volatilities is important, however, to understand the trend and the level of value of historical volatility..
