v0.6.0

Major Gekko upgrade!

Major changes:

• exchange integration has been updated to Gekko Broker:
  • only a few exchanges supported right now (GDAX, Binance, Poloniex, Bitfinex, Kraken & Coinfalcon)
  • live trading stability greatly improved
• updated gekko event system:
  • better event pipeline, read more here
  • more events, better documented
  • native gekko events are now relayed via the websocket server
• [UI] dedicated Gekko Manager:
  • allows for stopping, archiving and deleting of running Gekko instances
  • more visibility from the UI as to the current state of a gekko
    • messages show whether it is running
    • messages show whether it is warming up

Breaking APIs:

Gekko has multiple APIs:

• config files:
  • the UIconfig file has now moved to gekko/web/vue/public/UIconfig.js gekko/web/vue/dist/UIconfig.js. (see #2273 (comment))
• strategy API: unchanged
• sqlite SQL API: unchanged
• server API (http/ws):
  • now fully documented, see here
  • new endpoints for stopping/deleting gekkos
  • backtest now uses a plugin to manage output data called backtestResultExporter.
  • the websocket now relays native gekko events, see here
• exchange wrapper API, Gekko Broker requires a few minor changes to wrapper files, most notably:
  • file nesting is different, importing files outside gekko broker (gekko/exchange dir) is not allowed anymore
  • error handling is a lot more robust, however implementing properly requires a few response handle functions in the wrapper
  • cancelOrder: the callback needs to be passed err as well as filled and optionally more data regarding partial fills
  • checkOrder: the callback needs to be passed on object describing partial fills & order rejection
