Winklevoss IndexSM (also known as WinkDexSM) provides a blended price for bitcoins. WinkDex is calculated by blending the trading prices in U.S. dollars for the top three (by volume) qualified Bitcoin Exchanges during the previous two hour period using a volume-weighted exponential moving average. This proprietary formula weights transactions proportionally by volume as well as exponentially by time to give greater weight both to higher volume transactions and more recent transactions.
|Underlying Data||Uses actual transaction data||By using actual transaction data, WinkDex reflects the real price actually used to transfer bitcoins, rather than merely unfulfilled desired prices (such as ask-bid data) of potential exchange participants.|
|Volume Weighting||Accounts for actual price and volume of each transaction||By taking into consideration the number of bitcoins transacted at each price point, WinkDex allows for larger transactions to be given more weight than smaller transactions, reflecting the value of each transacted bitcoin from the underlying exchanges.|
|Time||Accounts for last 2 hours of trades||By including 2 hours of data (in contrast to just the last transaction), WinkDex lowers the risk of outlier transactions disproportionately impacting the WinkDex value.|
|Exponential Moving Average||Uses a volume-weighted exponential moving average of real world transaction data||By using an "exponential moving average," WinkDex not only takes into account all the transactions to occur over the prior 2 hours, but also gives greater weight to more recent transactions than older ones. Thus, if there is any sudden movement in the price of bitcoins, WinkDex will be sensitive to such movement, while limiting misleading impressions created by outlier transactions.|
|Number of Exchanges||Uses top 3 by volume qualified Bitcoin Exchanges||WinkDex tracks each actual trade of bitcoins for U.S. dollars on 5 qualified Bitcoin Exchanges. WinkDex's proprietary index dynamically determines the top 3 by volume of these exchanges during the prior 24 hour period. Unlike some other indices that hard code the selected exchanges, WinkDex's dynamic quality allows it to adjust promptly to changes in transaction volumes among the qualified exchanges.|
|Currency||Only transactions of bitcoins for U.S. dollars are considered||By including only electronic trading platforms on which users may buy and sell bitcoins with others in exchange for U.S. dollars, WinkDex avoids issues related to exchange rates used to convert transactions.|
