Hi. It is tricky to judge the application without a score or seeing a resume, but I will give you my best shot:
1. Being from LATAM, you are in an advantage. Schools like LATAM candicates. One AdCom member told me they consider them strong alums who are proud of their school and good to have
2. Staying within Finance is a positive
3. Your decision will be resting just on your work experience and GPA (hopefully the GPA is competitive)
4. Extra Curriculars only matter if you have achieved a lot. Reading books, traveling, or sailing is usually not very valuable unless you are sailing in the world cup (whatever it is called) or you are traveling to Somalia with humanitarian missions.

Seeing Stern as a WL and Simon with 50%, I am guessing a WL at Fuqua and I think Admit at Johnson but no $$

That's my crappy eval. (At the same time we have seen people get into HBS and WL'ed at Haas, WL'ed at Fuqua, Dinged at Stern and admitted at Kellogg). It's been an odder year than usual. Not having a score makes the adcom extra attention to the other few indicators they have. Make sure you do plenty of interview prep!
