While backtesting our algorithm, we detected some missing values in the bitfinex minute data stream. To be fair, the data is not exactly missing, but it seems like the values are not up-to-date for a few days/weeks.
Identified periods so far (bitfinex, btc_usd, minute):
04/01/2016 00:01am - 06/01/2016 00:00am - price is always 416.19
08/02/2016 06:03pm - 08/10/2016 03:53pm - price is always 604.1
01/19/2018 00:01am - 01/20/2018 00:00am - price is always 10,975
We eliminated the problem on our side, because the same issue occurs running the first sample algorithm from the beginner tutorial.
Are we missing something? Thanks for help!
