Thank for sharing.
For 1 contract, you would pay around 1.40-1.50 round trip with IB, so this is not too different.
But the $10 cap is definitely a game changer. Hopefully other brokers will follow.
P.S. To say "Compare that rate to any other firm on the planet" is not entirely accurate. Tradier has $40/month deal and RobinHodd has free trading - just 2 example. But Tom Sosnoff wouldn't be Tom Sosnoff without one of those remarks.
