Patrick McKenzie (patio11) is joined again by Ricki Heicklen to discuss the evolution of her trading education business, Arbor, one year after their first conversation. They dive deep into the pedagogy of trading, exploring how simulated markets teach concepts like adverse selection, team dynamics, and risk management through hands-on experience. Ricki shares war stories from the bootcamp trenches—infinite loop bugs that mirror Knight Capital's disaster, WiFi outages that create unexpected trading opportunities, and that the most successful trading teams often focus on internal team communication even more than trade execution or technical acumen.
