Wake up andrasnm
ARB Trading has its limits, so don't be fooled. There is no way a firm will give you unlimited margin. You'll have to pay for it one way or another. And I can assure you the firm is not going to pay for it. They will probably charge you haircuts.
See, its a numbers game. They may tell you no haircut, unlimited margin overnight, but first, they compute whether or not you are making enough money for them. Such as on your trading. For instance, you trade alot of volume. they are charging you .01 or higher. their cost is probably around .003-.004 at best. say you make 5,000. you'll have to give them 3,500 of what you make. You may be able to hold 5000 by 7000 in a spread, but there is no way that you are going to be able to hold 25,000 by 40,000 what ever the ratio is. If you make them enough in commission, then, and then its a maybe. so its a catch 22.
No risk? how about the risk that you can't make much. what if you made 20,000. you are going to give up 14,000 to them? that's not including a desk fee if they have one. are you getting volume rebates? like at other firms?
Also, three years seems like an eternity. wouldn't you say? This is a business. If someone has a better deal, then you leave. Sign it, and you can't leave. Its just like a regular job, if someone has better commissions, that could be a 100,000 dollar raise. You do the math.
I ain;t a wizard. So wake up and smell the coffee.
