Yes, you are absolute correct with your statement that "Sym Triangles" can break out on any side.
In most cases it helps to wait after the first break out on any such triangles. Waiting for a prove of what is going on. Some would argue: Then we are not from the begin with any occurring move. And yes: This is the point which would have to be accepted when waiting for any such prove in what ever defined way for the occurring market direction.
In my comment with the chart I thought more of an up direction and less on an ongoing down direction. This because of the MACD which is so far on the bottom. But I have to say that the parameters for MACD are not the standard once instead I changed them to double and this makes it very slow and gives a lot of room to the chart.
Also be aware that those observations are done on testing this market and less on ongoing trades in this market.
