This is very interesting indeed... Will the server be open source too so we can run our own instances? I think this is especially important for people who want to use non-standard candles. Also will it be able to be used for the backtesting too?
Thanks. I am planning on hosting all standard candle intervals (15min, 1h, 4h, 1d, etc.) for all those markets and providing them for free (as long as I can afford it). I could open source it all but storing all the data is not something as small as running a Gekko instance, there is
a lot of trade data flowing from all exchanges. Take a look at the mtgox sqlite database for example, it is over 4GB already.
I am now thinking of maybe turning this into a service where all standard candles for all those markets can be retrieved by everyone (free). And maybe I can see what other stuff can be calculated easily. I am thinking about things like spread graphs between different BTC/LTC (or other pure crypto) markets for arbitrage or maybe realtime datastreams to popular charting software like sierrachart. Right now I am just exploring all the different things I can do with this stuff.

This will be an
optional solution for Gekko, in no way will this be forced upon Gekko's users because nobody can easily check whether the candle data is not messed with.
