Create Realtime Data Pull from Exchange

Overview : I need to set up an real time feed of bitcoin prices from the Coinbase exchange to AWS. API: [login to view URL] Method : Use the FIX API, REST API, or Websocket Feed. The Goal is to make sure that the data is accurate every 10 seconds with what is reported in the exchange. The price and the volumes! Details : The AWS needs to store two files that are constantly updated every 10 seconds. Three fields need to be obtained, in Column A - Time Stamp , Column B - Bitcoin Price, Column C - Total Bid Volume, Column D - Total Ask Volume Both Files created need to be updated every 10 seconds. And they need to be in AWS so they can be pulled immediately. The two files should be called [login to view URL] , and [login to view URL] [login to view URL] 1) The first file needs to be constantly updated with the data, every 10 seconds. The data pulled every 10 seconds needs to be a new row in the file. The file should be hosted on AWS and we should be able to pull it via a url (i.e. [login to view URL]) 2) The second file needs to be constantly updated with the data, every 10 seconds, as well. But this file only needs to have data from the past 30 minutes. The data pulled every 10 seconds needs to be a new row in the file; AND the first row (from 30 minutes ago) needs to be deleted. So the file will have the latest 30 minutes of data. The file should be hosted on AWS and we should be able to pull it via a url (i.e. [login to view URL])
