Ethereum seems to be one of the more consistent coins in it's pattern. Thru most of 2017 while bullish it would repeatedly dip below previous support immediately to rebound. This made entries easy on the down turn once it dropped below support with a strong upswing anticipated after. As of late it's kept some of these overall properties, but is a little harder to find worthwhile entries and exits on due to the overall liquidity it's reached at this stage in the game. However if you watch the pattern you will see ETH is notorious for large impulses, and these make great indicators for where in the chart you are currently. If you follow along from these impulses you'll see that Eth has a very difficult time maintaining price after reaching new highs for long periods. Almost every ATH is followed by a very dramatic correction. Two GIANT M's in the middle of the circles shown are great examples in this pattern of this. Utilize the clear repeats of these to gauge an entry/exit.
