I have developed a black box day trading system and used to trade via IB API in the last two years, automatically. But IB is a retail broker and isn't really good enough for active prop trading. They have relative high commission rate and limited leverage, while unfortunately, I am lacking in capital. So I am trying to explore to the field of prop trading and looking for an office to work with. I prefer to work with the prop trading firm in alternative way as below: 1) If risk deposit is needed, I will ask a payout rate from 80%-100% with a fair commission structure. 2) If no risk deposit requested, I expect a payout rate of 50% with lowest commission fee. This is just an sudden idea in my mind. If you are running a prop trading office or are sophisticated in this industry, please discuss. I am totally open to your questions, opinions, advises, and bashing as well.
