What is the lowest commission structures you have encountered?.. or advertise what your paying or your firm charges. -per share -per trade and which one takes priority above..
IB's rate so far are the best I have seen. I have negotiated tier pricing with prime brokers with who we had over 300m in deposit and still they weren't beating IB. Service is different tho
Our lowest "advertised" rates are : $0.0010 Over 15,000,000 shares (Not tiered) $2.50 Over 10,000 trades https://www.lightspeed.com/pricing/commission/ Bob
transaction costs play a larger role in some systems. Some algo's try to detect orderflow patterns intraday. Using systems that trade on daily data bypasses this.
I don't need to know the details of your strategy, just what you are asking for, for a given monthly volume. I'd rather discuss this over the phone.
