I see. Thank you. You provide a lot of good information here on this site. THEY should pay YOU. Regards, RS
Besides the last point, I don't see how they are better than what IB offers (on its free platform /api).
You are happy at IB, I get it. Then stay. More than 50% of my current clients moved from IB. I guess they were not as happy as you. The common complaint from IB clients are customer support/communication/TWS/Auto liquidation/risk fee. And, in many cases, my rates are lower.
True DMA could be very important for certain types of HFT-like strategies. With IB, direct routing (through the API) is heavily disincentivized with extra fees. I've not ever traded such strategies, just theorized about them. Another thing to consider here is IB's margin interest rates are much better (than anyone else I've seen). If you use leverage overnight this can be a big cost.
lower. (lower=cheaper=better): https://www.interactivebrokers.com/en/index.php?f=1595 I believe no one even comes close. Please prove me wrong on that, if you can
Prop firms are more personalized compared to retail brokerage firms. You want to have a good relationship with your risk manager for when the market is chaotic. I can't even count all the times I got fucked over in my retail accounts because of system outages. Since I joined a prop firm my platform hasn't been down once. Commission rates are lower at my firm compared to IB and deals are negotiable. $100k at my firm could get you $3M in BP.
