Hi Jonathan,
I hope, that you had a good vacation with your family.
Did you regognized my posts 1 or 2 sites before, as the problem still persists? (#1435 and #1437)
Some markets on bittrex have wrong candles. Volume isn't correct and most parts of the candles are missing. Most worse market pair is NEO/BTC
