- Volatility — Enough daily range to profit, but not so wild that risk management becomes impossible.

- Tax efficiency — 60/40 tax treatment on all futures, regardless of holding period.
Common ES Trading Strategies
- Trend following — Identify the daily trend direction and take trades in that direction during the RTH session.
- Mean reversion — Trade pullbacks to VWAP, moving averages, or key support/resistance levels.
- Opening range breakout — Trade the breakout of the first 15-30 minute range after the 9:30 AM open. See our full guide on day trading ES futures strategies.
