NO ! You still aren't getting it, although the methodology has been explained to you in detail on other threads. If you were entitled to a better execution (even on a limit order) and you didn't receive it you got screwed.
I have read each explanation, but what you fail to understand is that if I place a limit order for 100 shares at $50 and get those 100 shares for $50 then what the Fu©k does it matter ...
What better execution should I be willing to get if I'm personally willing to pay the $50 a share price execution....I see the same price execution on my other broker accounts I pay a commission for when I put a limit buy order into a stock at a preferred price..
