Descending triangles imply similar lows and lower highs. Instead ever since June we had higher lows and lower highs (a narrowing pattern).
See, that's the issue with TA. Zoom in and it looks like a narrowing pattern, zoom out and it is a descending triangle. Which of the two is a valid signal. Most TA "experts" basically say "both" and when the breakout happens (in either direction) they exclaim "told you so".
Which is why most TA is BS, too little signal over noise...
