Quote from pairsarb:
10K 15K whatever 25K...if your strategy works, and you pay by the share, the only fixed cost is your data feeds.
There is a little smoke here. Firms like you to put up the most capital possible beacuse they dont' like monitoring your risk tick by tick. They also know that more buying power means more soft dollars (commissions).
Trust me, I have done it that way. And while I have more capital, I don't leave a lot with the firm. Call me crazy.
If you are a decdent trader, then you probably should have more than 10K to put up. But if part of your risk strategy with a firm is not to put up a lot of capital, then you can still make money on 10K 15K (even 5K).
You should know your max drawdowns and plane your trade size accordingly. So, if you have 5K, you are not gonig to trade 1000 share pairs on each side, because a .06 cent move on each pair loses you $120 dollars and thats more than the risk you might want to take per day. Id say at $5k, you would probably want to risk no more tha $50.00 per day. That's why the firms want more deposit, cause that kind of trading is generally low volume.
Since stock trading is SCALABLE (100 shares, 50 shares, etc) you can reduce your trade size to accord with your equity level. Its MUCH harder to do this with commodities. That's why prop firms are in business. If everyone had 1MM to allocate to trading, prop firms would be next on the chopping block.
Don't let anyone tell you that you need X amount of dollars to make money, to put it more accurately, THE FIRM needs X amount of dollars to make it worth their time. If you are a beginnger, yes, count on 25K as your education money. THat's a fair argument. 'Firms know that beginners will lose most money not to their commissions but to the market, so even then they don't like it too much. A lower deposit is even worse for them.
HInt: it's probably easier to find a few people with 10K each to back you, than to trade with 5K or 10K as a newbie, but still, if you can make money trading 50 shares at a time with 5K, you can do it with 100 shares at 10K, or 200 shares at 20K, etc.
One work on getting backed: be honest with people about what you are trying to do. You might be surprised what comes of it if your true intention is to trade.
There is some stuff in the regulatory literature about trading less than 100 shares, but that's usually, again, a headache for the firm that they would rather not deal with. It's not illegal.
Just talk to pair or merger arb traders, who trade lots of 750 225 75 etc. No firm will turn away their volume on odd lots.
Anyway, i ramble. But if your trading is profitable, it IS scalable save the fixed cost of data fees. And at most that would be like $300.00 month if you can't get it covered from small volume. You put that 300.00 in as a cost of doing business, its tax deductible too. In the lowest tax bracket, it's already only $200.00 per month after taxes.
Trading is probably the lowest cost business to start and maintain. You can even trade from a storage unit with a huge bank of computers. If you ahve a good strategy and a good firm, and some capital, you can run this business.
