"It wouldn't be possible to do at a retail firm- as I tend to be very active, need bullets, professional margin, the fastest executions (There are a few others always in competition with me), and very cheap commissions for the system I've been doing /learning. - rtharp"
just to add some tinder to the fire:
the fastest executions: why would a prop shop offer faster
executions than a properly structured retail shop. I would be surprised if each and every office of each prop firm routes their orders directly to the exchanges. I would suspect that you have T1 lines that route to the server at the main hub which in turn routes to the various exchanges. Thus I do not see how this would offer faster executions than the direct access "retail" firms which offer the same routing. (T1 lines are not the exclusive domain of prop shops).
professional margin: with 4:1 margin offered now this is less of an issue. I would even argue that higher margin is dangerous to the more inexperienced traders.
bullets: I will not argue this one as it is an advantage - other than the cost. But one thing no one ever mentions: this assumes that you are RIGHT on the next tick. i.e. one 1 penny uptick you would be able to short elsewhere without the cost of a bullet.
cheap commissions: look around i don't see the advantage
If you your system is so great, it wouldn't matter if you are in bed or at an office.
In the end, some people need or thrive on the stimulus provided by people around them - others don't. some thrive being around successful traders and learning from them (assuming the successful traders are willing to teach others how they make money) - others don't. some people don't want to be surrounded by others questioning why they did this or why did you do that - some don't care. some people desire the consistency and the motivation a desk an office environment provide - others don't need or want this. I could go on and on.
There is no one way to make money trading. At home, creating your own office, go to a prop shop there are pros & cons of each. your own individual situation will determine what you need. The argument that one is so much better over the other - i don't buy it.
to each his own.
