Obviously somebody is able to trade at prices that I cannot during these price capping episodes
This is the key thing. These price caps are unfair because they do not apply to everyone. IB prides itself to give clients the technology to compete, but in this case, they actively put us at a disadvantage. They reduce their commission revenue, too.
--> IB: replace price caps with a second confirmation pop-up window (to avoid data entry errors) unless and until the industry and exchanges uniformly agree to enforce price caps.
