Is that why comissions are low?

In any case I don't know their business model. I don't know how much money they make and on what. Do they trade against their clients? I don't think there is any real proof of that. I don't know if 10% or 90% of their clients lose money. Are people likely to lose more money day-trading? I guess so. But if they provide good service is what matters to me.

I believe comissions could be low, and we'll see comissions to go down across the board eventually.

Btw, day trading firms ( like All-Tech ) are really srary thing. But I think they charge much more.
