Hey I'm also in the charting/data space for cryptocoins. The focus is on alerting (email) due to price movements. Currently its a simple percent-change trigger, with more complex triggers on the way (such as two-coin correlation). The roadmap includes user-provided code that runs on our environment for very customized triggers/signals. https://cointhink.com

Its written in Elm/Go, using protobuf-in-json over a websocket. I've been working on it for the past nine months and its becoming more useful all the time. All the code is up at https://github.com/cointhink/ Working with elm has been amazing.
