The purpose of bill calling service is to attract customers to open accounts and earn high fees or charges.

If a trader can continue to make profits in his own trading, he will not want to be bullish.

In other words, the caller must lose money in his firm offer.

But that doesn't mean shouting is useless. People are lazy. Anyway, it is a loss. I can still look forward to it when I give it to the teacher. Although my expectations will be dashed, I didn't know at first, because I had expectations.

I hope it helps you.
