Abstract: Methods and systems for a volatility prediction are provided. The method includes receiving, via a graphical user interface, a first user input for a first currency. The method also includes receiving, via the graphical user interface, a second user input for a second currency. The method also includes receiving, via the graphical user interface, a third user input for a first time period. The method also includes determining, based on a technical indicator data associated with an exchange rate between the first and the second currency, a first volatility for the exchange rate. The method also includes determining, based on one or more economic events data, a second volatility for the exchange rate. The method also includes determining, based on a sentiment indicator associated with the exchange rate between the first and the second currency, a third volatility for the exchange rate.

Abstract: Retention mechanisms for bicycle drive trains are disclosed. In some embodiments, a retention mechanism may include a backplate having at least one spur, at least one chain ring coupled to the backplate, and a slider coupled to the spur. The slider may be positioned between the at least one chain ring and a bicycle chain, and may include at least one track and at least one chain guide (e.g., an O-ring or ring component) seated in the track. The at least one chain guide may be configured to rotate about the track while applying tension to the bicycle chain so as to reduce friction and/or dampen noise.

Abstract: Methods, systems, and computer programs are presented for executing game operations. One method includes an operation for receiving a request from a player to acquire a first game asset to be utilized in the game, the first game asset being associated with a token usable in the real world outside the game. After assigning the first game asset to the player in the game, the player is rewarded in the game with a second asset in response to the request. Further, the method includes an operation for detecting a commercial operation executed outside the game by the player with the token, and the player is rewarded in the game with a third asset in response to the detecting.
