Trading Strategies for Indices

Opening Range Breakout (ORB)

Mark the high and low of the first 15-60 minutes. Trade the breakout in either direction. Works especially well on the S&P 500.

VWAP Mean Reversion

When price deviates significantly from VWAP (>0.5-1%), trade back toward it. Works best in the first 2 hours of trading.

Session High/Low

Mark the high and low of the London session (3 AM - 12 PM EST). NY session often breaks these levels.

Risk Considerations

• Indices have excellent liquidity (tight spreads)
• Use limit orders, not market orders, during news
• Index CFDs have overnight swap fees — avoid holding through rollover
• Futures have quarterly expiry dates

All index trades should be logged in a trading journal to track which strategy works best for your personality.
