He has been at the forefront of applying computer technology to automate trading and brokerage processes since soon after he emigrated from Hungary to the United States in 1965.</p> <p>In 1977, Peterffy started his own business with $200,000 savings, writing programs and building systems to value and trade stocks and options, as a market-maker on the American Stock Exchange. He was the first to build mathematical models to calculate and disseminate continuous bid and offer quotations and to develop a tablet computer for use by his employees trading on exchange floors. By the late 80s, Peterffy developed a fully integrated, automated market-making system for stocks, options, and futures, that grew into a digital network encompassing most of the world’s exchanges. Starting in 1993, brokerage interfaces and customers were added to this network that continues to expand in products and customers all over the world.</p> <p>Today, Interactive Brokers is one of the largest publicly traded electronic brokers with a market capitalization of over $100 billion. The firm provides direct access to trade executions, clearing, and custodial services for a wide variety of products, including stocks, options, futures, forex, bonds, CFDs, and funds on over 170 markets and in up to 29 currencies around the world.</p> <hr /> <p style="text-align: center;"><strong>Check this out and find out more at: <a href="https://www.interactivebrokers.com/">http://www.interactivebrokers.com/</a></strong><a href="https://www.interactivebrokers.com/mkt/?src=tdi1&#38;url=%2Fen%2Findex.php%3Ff%3D1338" target="_blank" rel="noopener noreferrer"><img loading="lazy" decoding="async" class="aligncenter wp-image-54327" src="https://thedisciplinedinvestor.com/blog/wp-content/uploads/2020/12/InteractiveBrokers_logo1-e1607262448146.jpg" alt="Interactive Brokers - Why IB?" width="393" height="87" /></a></p> <hr /> <p style="text-align: center;"><a class="twitter-follow-button" href="https://twitter.com/andrewhorowitz" data-size="large" data-show-count="false">Follow @andrewhorowitz</a><script async="" src="//platform.twitter.com/widgets.js" charset="utf-8"></script></p> <hr /> <p style="text-align: center;"><strong>Looking for style diversification?</strong> More information on the TDI Managed Growth Strategy &#8211; <strong><a href="https://thedisciplinedinvestor.com/blog/tdi-strategy/">HERE</a></strong></p> <hr /> <p style="text-align: center;">Stocks mentioned in this episode: (OIL), (GLD), (SPY), (QQQ)</p>
