0-DTE began in 2021, after Ernie ended his 30-year career on Wall Street. Even though he shut down his hedge fund, Ernie still traded his own money. He joined some retail trading groups for the sense of community, and quickly realized retail traders have been led down the wrong path. Because most mainstream “best practices” fly in the face of how professionals are trained to trade. So Ernie started his new mission, helping regular people trade with the same skill and consistency as professional traders.
