Technically speaking this is not a symmetric triangle as the sym triangle bottom (in red color) has not been tested at least 2 times. Only the top has been tested 3 times.
So far we see only a wedge with the red trend line on the top and black trend line at the bottom. If the red trend line at the bottom gets tested once again we can call this a sym triangle.
My apologies for premature identification.
Now we can call this pattern as a sym triangle
