I was looking at some ticker data from Poloniex for GAS/ETH and came across an extreme increase in price (15x) from one ticker (price=0.05911633) to the next (price=0.96).
This happens In the image at 23:15:23 and continues till 23:17:39, after which everything is normal again. This situation doesn't happen for GAS/BTC.

Can someone explain what happened here?
