How to get the Ripple (XRP/USD) inside of NinjaTrader 8?
Setting Up The Connection Via Coinbase
You will need to first double click on the coinbase connection so that it drops down into the configured box. You can then configure the rest of the connection.
Uncheck "Connect on start up" which we'll do so that we can manually connect each time after the NinjaTrader 8 platform has loaded. We do this so that the platform loads up faster and doesn't spend the time downloading all the data during the start up mode since it won't be getting it from the faster NinjaTrader 8 servers.
Make sure the option NinjaTrader historical data server is unchecked. Because the ripple is not on NinjaTrader's historical data servers, you will uncheck this so that the data will be read in directly from Coinbase.
