- Growing up in Tough Conditions: He grew up under a communist government and lacked basic freedoms. His early life was very hard, and he decided to move to America to start a new life.
- Moving to New York: In 1965, when he turned 21, he left Hungary and moved to New York City for a better life. He arrived in the US with no money and didn’t speak English. His father only gave him 100 dollars, telling him to work hard and build a better future.
Starting His Career: From Draftsman to Computer Programmer
When Thomas Peterffy moved to America, he didn’t speak English. His one brave decision changed his life forever.
- Learning Computer Skills: To survive in America, he had to work hard right away. He started working as a draftsman for an engineering firm.

This decision successfully changed his entire life.

Entering Wall Street: His First Steps into Stock Trading
After learning how to program computers, Thomas decided to bring his digital skills to the world of financial markets.
- Buying an Exchange Seat: Thomas used his early savings to buy a trading seat on the American Stock Exchange in 1977. This allowed him to trade options directly on the floor. It was a major financial risk, but it also gave him direct market access he needed to test his ideas
- Using Math Over Guesses: Most traders back then made deals based on rumors or basic instincts. Unlike them, he used his programming skills and created math formulas to calculate the true value of stock options. This was a big advantage and allowed him to spot profitable trades much faster and more accurately than others.

This helped Timber Hill trade thousands of different options across multiple markets completely error-free.
