%%Me and my family & friends follow the same internal bot, manually trading/testing a few strategies, and sometimes they’ve got better fills (or faster) via Robinhood than I’ve got with IB. Sometimes I didn’t get a fill at all when the price ran away, while they were able to grab a few shares.
Of course this is subjective because we all place orders differently, while I never notice when I get the best fills or why/how they’re better. It’s just 2 or 3 times when i was surprised that for some reason their fills on Robinhood were clearly better, possibly due to Robinhood’s or Citadel’s internal inventory. At least it made me think that fills may not be so bad with free commissions.
On another hand, IB may be better than most brokers with shorting hard-to-borrow stocks (while Robinhood doesn’t support shorting at all), as most of my short orders do go through at IB without any specific locate fees or requirements, even though.sometimes i have to wait a few hours for other shorts to blow up and release some shares before some of my orders go through. (I usually short a few $0.50-$5 stocks per day)
But IB’s shorting ability may decline when traders move to other brokerages, even though hard-to-borrow locate fees and short %interest rates may be one of remaining opportunities for brokers to make money on.

A critical question is how much emphasis we can put on IB's claim that they improve price execution by 0.0043 as stated above. I believe Ameritrade claim they improve price execution as well. Let me look into that.
The same question was also asked in one of the other threads that talk about this new IBKR offer (and other brokers which have followed suit). I guess we'll have to wait until someone runs the same trades in both IBKR accounts (Lite and Pro) and reports the differences in fills they get. Only by then will we have an indication how much the customer is paying for commission-free trading.
%% Good points;I wonder if someone is actually going to take the time to run the same trades sumultaneously. And even if done, how do you know that the fill on any trade would have been better or worse at any given moment in time? Liquidity changes and the first order received gets the goose. The second one may or may not.
%%How does this work? There are SEC fees that have to be paid, and no one can avoid that. So they will lose money.

,They will make it up somewhere.
%%Zero risk $$$. It is all free money. ZERO RISK!
HI Rick, I'm down 300 points. How are you doing? Remember when you typed recently that it does not matter where you buy, the market will make you whole again? How you feeling now about that angle?
