ECA downward channel after 5th rejection from key resistance

ECA.TO has been consolidating in this downward channel for the past 7 weeks after a 5th rejection from the $18ish area. This is clearly a significant breakout resistance going back for 3 years, and it makes me wonder if there is a fundamental reason for this resistance (similar to the fundamental reason for TSLA and $360.00 resistance).

The long entry on this is frustrating to pinpoint because the exact resistance is unclear, as numerous higher highs since 2015 have been met with immediate pullbacks.

This will be a really nice long once that level does break with a profit target just under $22.00.

Does anybody know if there are fundamentals concerning ECA.TO and the $18 range? I'd love to hear your thoughts!
