I've talked with a couple Prop shops and they've basically stated that if your profitable, we'll give you as much buying power as you need. They conveniently refuse to give a precise ratio of capital contributed to buying power, so I'm a bit skeptical. After all, if I contributed 50K of my own money, and was given effectively 40 to 1 leverage, I could make about 100K per year tax free by investing in municipal bonds. Not sure if prop shops, who make their money on commissions, would allow this To those who trade at prop shops, how does this really work? The firms I talked with did indicate that they will give a lot more leverage intraday or on open only orders. However, if you are holding overnight or longer-term positions, the amount of leverage one can get is a lot more limited. Just wanted to get the perspectives, positive and negative, from those who have been there, don that, at prop shops.
