my thoughts

Only if you love this career otherwise may not worth much to change career if you are already in IT.
it's much harder to get in and survive the first two years.
It's very challenge to get in good firms(hedge fund or mutual fund or proprietary trading fund).
You don't make a lot in not-god firms.
tuition is very high for FE. You still works on technology but longer hours. Bonus could be anywhere from 20k o 200k depends on where and when.
Need connection to get in the industry, remember this, network is king.
