Fave Gen3 stocks broker?

I know that Collective2 is broker agnostic, so this question is not directed at them.

I would rather ask the forum at large, anyone who has experience with the three Gen3 STOCK brokers available…which one is your favorite? Which one is the best to go with (with respect to autotrading stocks) and why?

The three choices are:

1. Options Xpress

2. OpenEcry

3. OEC Equities

OpenEcry uses OEC Equities, so I’m not quite sure how much of a difference there is between #2 and #3.

But, I’d like to hear some opinions based on your experiences.

In particular, if you Gen3 autotraded it with STOCKS, how well did it work for you?

Thanks in advance!
