Gekko will bug when asking bitcoincharts for data older than 150000 seconds

[askmike]

When asking for data from over 150,000 seconds ago Gekko will receive candles where the oldest one is a lot newer than the since date. This will cause the first couple of candles to be NaN and all EMA calculations will glitch from that point.

[askmike]

The API for bitcoincharts has changed* and does not support the parameter start anymore that Gekko uses to let bitcoinCharts know the dates of the trades it needs to have.

* Here are the old docs with start, here are the new docs without start.

This means that on default settings Gekko will not work on BTC-e, a current workaround can be found in the thread.

[askmike]

Gekko now gives proper errors about whether it is able to fetch trade data or not.

Bitcoincharts has changed it's API documentation again, it now states that the start parameter should work (the parameter Gekko is dependent on). It works for a couple of exchanges but not for BTC-e in my testing. I've reached out to them to see if they can fix it.

If anyone knows any other source for retrieving historical trade data from BTC-e please let me know!
