Rather sounds like you don't understand anything. If I limit buy on one exchange I might get filled at 15.995 and 16.00 on another. Both are valid fills but one is clearly a lot better.
On average? I highly doubt it. On certain occasions you might but I'm interested in the averages, statistically meaningful numbers. It simply makes no sense to pay for a feed, get an equal or worse price - it's a losing business model. I suggest you run comparisons between exchanges like IEX and ARCA etc. to see how big the differences really are. It's quite amazing.
IB just wants to bait and switch newbs into regular accounts. They'll probably be educating the newbs on order execution quality as time goes on via email spam. And if they don't move they just clean up on order flow comms. I'm sure they'll offer better service than the other no fee brokers. Pretty smart move really.
if you think .005 is a LOT better , you must trade 10k blocks all day. My trading does not depend on 1/2 cent diff in execution, if yours does you're not doing it right Maybe we at ET can help you improve
A new trader or anyone trading slowly, SHOULD prefer a free platform. It's 2019, and IB is actually charging too much for trades. It cripples the ability to trade for profit or break even . You cant break even if you have to pay them $1 per hundred. Thats a $100 a day on 1000 shares 10 times , at break even . I refuse to trade often , and pay that kind of vig, to trade against co located bots.
does IB Lite cover MOC or MOO orders? Also, have you guys tried Alpaca? it's API-enabled free commission brokerage. It's relatively new, but since it allows API trading AND offers free commissions, it's probably attractive to many on this forum...
One thing does not follow from the other. You need a handle on math: https://www.interactivebrokers.com/en/index.php?f=1590 You are not trading against bots. Bots trade for epithelial cells -- you trade for chunks of hide. The world is not out to get you -- they don't care that much.
