# FatTail Labs > Trading education built on capital preservation: "First, stop the bleeding." > Courses, a daily live trading room, and resources teaching defined-risk, > convex options structures — butterflies on same-day-expiration (0-DTE) index > options above all. Founded by Ernie Varitimos (0-DTE.com, the 0DTE Live Show > on YouTube). The doctrine: most trading accounts die from unbounded losers, > not from missing winners — survive first, then position to harvest the fat > tails. Education builds capacity, not dependency.
