Quote from FrankSlaughtery:
i noticed on their website that they charge a per side fee for someone of the platforms (esp NT) whereas other brokers don't (if you don't use static DOM for example). can anyone comment on this. i agree that DDT has the cheapest rates i've ever seen but they're a little bit more expensive adding $0.10 (or whatever the fee is) to each side.
Howard told me that they pass through all discounts, specials, and reduced rates from the platform vendors at cost with no markup ever, so I am confident that if the platform vendor offers a lower price, they can provide it. Just email NT or DDT for confirmation.
On the other hand, there are one or two brokers who include the platform fee bundled in commissions that are much higher. Typically these brokers have *much* higher commissions, not just a little bit higher.
