This is a perfect chart and a trade on a break of the 17 and then a panic drop are very good, the only issue is that, that particular break was when ETH took a hard fall.. and everything was falling, so some things had a hard time bouncing properly, with the whole market going down... several trades had a hard time on July 7th... So GNT in particular fell to .000135 and bounced to .000158 .. not quite making all the way back to 17s.. the .000135 became a reliable base and when it dropped to .00009s later it bounced perfect.. I expect the chart will correct itself and get back to 17s soon.. but I wouldn't wait around for that.. I would be trading any future cracks, but with the knowledge that there was one time it didnt quite make the bounce.. (although that was partly due to the market activities at the time)
