Amazon had a strong double top formation and it looks like more movement to the downside. There are 2 possibilities either to go short here a bit below the 50% retracement or to wait for a second leg up, which could result in a gartley pattern completion around the 78.6% retracement. With the last one the risk - reward is much better, but you could miss the move if it does not go up there. I would put the stop in either case just above the 88.6% retracement. If amazon gaps down big on tuesday I will not chase the trade wit stocks because the R / R will become lower than 1:1.
