The red dashed lines are representing a descending wedge, which can be broken, and in that moment btc will test the smaller wedge (marked in teal) and continue to go down to test the bottom of a bigger wedge (marked in blue).
We also have a trend line (marked in pink) which will be hard to break. If btc goes up to test the trend line or the wedge I suggest entering a short at 19200- 19300, we just have to see if btc will break the descending wedge
