Oliver started to trade in 1981.

In 1986, he started his professional trading career. He spent about 5 very difficult years to achieve consistency, it can be said that those were the most difficult years of his entire life.

At that time there were no mentors, seminars, very few books, or content that a trader in development could find or follow.

You had to be hired by an important Wall Street firm or learn by trial and error as he did.

This process took him a lot of time, money, and even unpleasantness with his own family to accomplish. But he did it, and even so, it wasn't until 1994 that he started teaching professional traders his method.

He was one of the first teachers in the trading industry. He broke the rules of those times because the unwritten law was "keep everything private and secret."
