You get DMA, OTC and super leverage like Hwang. You can't do HFT with IB
Yes, but realistically you can't do HFT with anyone unless you have your own membership, otherwise, you will always be subject to the brokers at best high touch treatment, which will add at a minimum 10 MS via their risk checks. So in my view anyone that is building strategies to lift the micro sec discrepancies that may be present in the price, the relative or absolute cannot do it with a broker infra in between.
or HFT is merely related to the volume throughput?
. But the logic is scenario-based, and different scenarios will trigger other algos; if it's a hedge order in the underlying or execution of the derivatives contract.
