Futures offer unique advantages: massive leverage (control $100K+ with $5K margin), nearly 24-hour markets (Sunday–Friday), tax advantages (60/40 rule: 60% long-term, 40% short-term gains), no PDT rule (unlike stocks), and the ability to profit in both up and down markets. The most traded futures: ES (S&P 500), NQ (Nasdaq 100), CL (Crude Oil), GC (Gold), ZB (T-Bonds).
