Ive had Brown as my retail customer accoutn for my long term trading for over 15 years...I had never used the net version until recently when I decided to try "investing" again...and found their fills to be the worst ever. Hoenstly, I dont know how it compares to other discount net brokers. I have a feeling they all work the same: they send their orders to regional, smaller exchanges. They told me they do this because it is cheaper than NYSE. That may be true - but we get HORRIBLE fills! Twice in a week, I had to call them to complain about my fills. I knew where I should have gottent he stock because I am also a daytrader and see every trades that happen. They were off by more than $1 on one occassion and 50 cetns on the second. Thats because it went to the regionals, they said..and that they would have corrected the price even if I did not call them...lol...Yea right! This problem goes for the options too. I had to complain about 2 options fills because of bad fills...and they did correct them. But if you are not aware of what is going on..or away from desk...or whatever...in other words, if you are just another "Joe the farmer".....you are in BIG trouble with terrible fills.
I asked them if I can preference my order to NYSE, for example... or CBOE for my options.... they said I can but it will cost me something like $35 for stocks and whatever for options..at that point, I hung up.
