Once a stock price crosses a predefined threshold, the app publishes a message to PubNub network on a particular channel.The stock exchange captures the random movement of stock prices and publishes them.The sequence of operations to activate voice alerts for the Tradebot is as follows. PubNub works on the publish/subscribe model of communication, where a publisher can publish a message on a channel, and any subscriber subscribed to that channel can receive it. PubNub Functions host the service side business logic for the Tradebot and orchestrates the client requests with the Text To Speech service. The HTTP REST APIs access this service, via PubNub Functions, a serverless microservice.
The speech synthesis capabilities of Watson are what gives the Tradebot its voice capabilities. The TradeBot system makes use of two major components: Watson Text-to-Speech and PubNub Functions. The TradeBot will give natural sounding feedback in male voice if the lower threshold is crossed and in female voice if upper threshold is crossed. You’ll be able to configure the Tradebot with some stock counters and define their upper and lower thresholds. It acts as a friendly stock trading assistant by giving out audible alerts when your favorite stock crosses predefined upper or lower limit. TradeBot is a voice automated stock trading plugin.
