Do you know how to understand that broker provides favorable trading conditions? You don't know? I will tell you by the example of this broker =) If you have trading experience, then most likely you analyze your trading. Or maybe you write down every trade you make. If you do that, you can easily understand how profitable trading with company is. For example, you calculate your profits and can't understand why you have less in your account than you have in your records. It turns out that broker took part of your profit through commissions. I don't have such situation here. Because I opened trading account without commissions. I hope now I understand what favorable trading conditions are ;)
