Abstract: A computing device is configured for determining a sentiment index for display on a user interface of a destination computing device. The computing device tracks and receives real-time actual transaction activity information detailing each transaction performed over a past time period for each user from a plurality of users associated with an entity. Then, a set of proxy components are determined to represent the transaction activity information based on types of transactions in the transaction activity information. The sentiment index is generated having a value representing market sentiment for confidence at a current time in performing transactions based on a weighted sum and/or difference of the set of proxy components and display the value of the sentiment index on an interactive display of the user interface for subsequent use in performing further transactions.
