Thanks for the links. Definitely interested.
We have just announced
the Beta Version of a general purpose bot platform with open-source Trading Strategy framework connected to the Btc market.
Of course those traditional services are way ahead in terms of financial features, but they're also expensive hosted service currently disconnected from the btc market.
We don't expect to provide the same capabilities any time soon, yet simulations against the bitcoincharts API are definitely on the road map, and it shouldn't be too hard to update the source code with a dedicated predictive trading framework.
It's a different path to be honest: our solution is a tiny version of what those services offer, but it's a flexible version you can install for yourself and customize to start selling those actual same kind of services.
Please let us know if you want to look in that area too.
