Ascending Triangle forming on 1H chart MEX

The current ranging moves in the 3400-3430 area seems to form an ascending triangle ,
indicating an upward breakout. The triangle playing out sets my buying zone to the 3390-3410 area.
The 0.78 Fib Retracement seems to be a first target, 3483 as the 100% retracement probably be taken
in wicks.
