VLRS (Controladora Vuela Compañía de Aviación, S.A.B. de C.V.) will trigger a short entry on a break below 15.77 with a suggested stop on a close above 16.70 (lower, if only targeting T1 or T2). Such a breakdown will have taken VLRS, a Mexican based transportation services company, below both its primary uptrend line as well as the neckline of this Head & Shoulders topping pattern.
