This slack bot will allow you to monitor any crypto currency trading on any major exchanges. It uses ccxt as well as pymarketcap to fetch all the information. It allows the user to check the current price, set alarms and as well as generating image for the top gainers/losers. Eventuall I would like to implement graphing feature such as candlesticks,RSI,MCAP....
The bot uses flask on the backend and as well as celery + rabbitmq to process requests. It should in theory allows multiple users to make requests to the bot. I currently have it deployed on a RPi 2.
