Well as you can see, the market is going sideways. And we are all hopeful that it will soon go from sidwase to an uptrend again. Although, for now we are still led to believe that the bears will win. Until we see a noticeable uptrend.
Trading short at the top of the 2nd purple trend line marked with a -19 degree angle would be my opinionated position to open short. And trading short until we reach the green line where the Fibonacci tell us the trend may change direction is my opinion as to where you should close the trade.
