Gekko 0.6 released

[mark.sch]

@mark.sch I've summarized everything in a doc file, see here: https://github.com/askmike/gekko/blob/pr...per_api.md

@Henry151 I fixed this ~40 minutes ago, see here: https://github.com/askmike/gekko/commit/...d45fcbbcbe are you running the latest commit on that branch?

@aslmike awesome, I will take a closer look to your detailed response. Right now I am close to finalize hitbtc exchange+import into 0.5. Candle writing is working in realtime mode to db and also in import mode. Trading is implemented and needs testing - using the ccxt lib. When db is prefilled with imports and gekko starts with stitching in next realtime run, it fetches new candles but never write it back to db. The same happens here with kraken too. Do you maybe have a reported issue in mind, which can get me into direction?

@henry151 I remember the same binance complaint yesterday also on v0.6. Out of my head it was a
 missing library. npm install binance and npm install poloniex.js fixed this error when testing on binance and poloniex. However my v0.6 then got stuck with lodash version dependency probs.
