I am willing to admit that the easiest money has already been made from $71ish to $75ish. But there could be more on the horizon. The break of the red DT line was your hint that the short trade may be over. Now the green UT line is in charge. A long investment here is prudent until the price of GPRO closes below the green UT line. $75ish, $79ish, and $84ish are places to look for a bit of resistance.
Remember, when GPRO closes below the green UT line, you should take your profits (or losses) & run. Good Luck!
After hours edit -
1) GPRO did close below the green UT line. If you just started a long position you should be out of the trade.
2) If you went long before today, feel free to adjust the green UT line to accommodate today's candles. $73.25 should be your line in the sand so you still have some profits left if / when you get stopped out.
