Before Brent Donnelly became the president of Spectra Markets and the author of several books, he had a long career in trading: Brent got into FX markets in top-tier banks in the U.S., traded the dot-com bubble with his own money, and was at Lehman Brothers when it collapsed. In this special episode of My Life in 4 Trades, Brent joins guest host Andreas Steno Larsen to share his perspective on trading, including the big regrets that became some of his best life lessons.
