The notion of binary option was last heard at a grammar school in an hour of macroeconomics or microeconomics, or as the object was named. Maybe only economics. He never knew about finance, and because he never spoke to a financial broker or a stock expert, he never needed that knowledge. He understood that this was something with trade and stock manipulation, and also the market situation, but it didn't know exactly how it was related.
He was essentially not interested in it, but he was quite looking forward to meeting today after twenty years of high school. With most of these people he did not see from the graduation, the rest sometimes met at the university. Except Teresa, with whom they attended for three years after the end of college, he did not know anybody well.
