ETH seems to follow BTC's up- and downtrend. This week we've reached a new ATH, on high time frame ETH seems really bullish and till the end of next week it could reach 2k. 4h chart shows some slowdown, and I expect a smaller correction, as soon as BTC starts to rally I expect ETH will follow the trend soon. The bullish trend would turn if the price dropped 1600 or below, but 1,7k is more likely pushes the price back to ATH and hopefully above it.

Hourly chart shows a strong support level at 1,7k, the price may drop till 1,6k, but I wouldn't worry at this level, if we lose 1,6k that would be a trend changer.
