CCXT arbitrage bot

I currently have an arbitrage bot that has access to a number of exchanges from the CCXT library. I mainly use 6 of the 100 available and there is another exchange that must be manually added. It currently uses rest API but I need it to run off WebSocket to be faster. It needs access to forex rates via websocket. It must be a website that is mobile friendly. It needs best security to safeguard keys.
