It's a pretty good score for the colleges you're applying to. Frankly speaking, Q 169+ and V 155+ is a good bet for most of the colleges. However, since there are other elements which directly affect your application, GRE alone can't be a deciding factor. I know a couple of people who got into top universities with a lesser score. I would also recommend you to target other top universities such as UCB, Baruch, Cornell etc.
All the best!
Seems like a great score, full score on the Math section. Some MFE programs say that they only look at your Quant score. Instead of putting more time into GRE studying, you could develop other parts of your application, possibly.
