XRP-BTC market will be visible in 4.7
Problem with Bitstamp Api is that they create a Page for Every Coin :
https://www.bitstamp.net/api/

Example for ticker

GET   https://www.bitstamp.net/api/v2/ticker/btcusd/
GET   https://www.bitstamp.net/api/v2/ticker/btceur/
GET   https://www.bitstamp.net/api/v2/ticker/eurusd/
GET   https://www.bitstamp.net/api/v2/ticker/xrpusd/
GET   https://www.bitstamp.net/api/v2/ticker/xrpeur/

And there's no call to dynamically load market list (btcusd,btceur,eurusd etc....)
So everytime Bitstamp Add a market i need to manually add the new market id to CAT internal market list.

Usually there's an Api to get MarketList dynamically, but not on Bitstamp
