it seems like prop firms have a pool of capital and allow its traders to manage portion of it. so basically the aggregate traders can be quantitatively defined, and various risk models can be applied if all the traders are using methodology in the same ball park? where does swiftrade get its vast amount of pool of capital from, do they raise it from public, and hedge funds ? what is the aggregate annual return of prop firms like? i've heard ranges from negatives to a few hundred.... how does one start their own trading operation? what does it mean by running a floor ? what is the cost of running a subbranch of swiftrade?
