I've created and used dozens of custom indicators and systems for ESignal, Omnitrader and VisualTrader over the years and it would be great to play around with Crypto's using those applications but I haven't seen a data provider which offers feeds for them.

Sure the webpage quote providers are fine and dandy (a really good effort), but are toys compared to real trading software.

None of the big data houses are offering it (Esignal, Metastock, IqFeed)....

Anyone get their trading platform to interface with some sort of crypto feed?
