Distinct time periods during the trading day when different global financial centers are active, affecting liquidity and volatility.
Trading sessions refer to the major global market hours when different financial centers are open. Understanding sessions is crucial for optimizing trade timing and managing risk.

Session Overlaps
- London/New York (8 AM – 12 PM ET): Highest volume and volatility. Best time for day trading.
- Asian/London (3 AM – 4 AM ET): Brief overlap with moderate activity.
Why Sessions Matter for Prop Trading
Volatility Differences
- Asian session: Low volatility, range-bound markets
- London open: Sharp moves as European institutions enter
- New York open: Second wave of volatility, especially 8:30 AM economic releases
Session-Based Rules
- Some firms restrict trading to specific sessions
- Many firms reset daily loss limits at 5:00 PM ET (start of Asian session)
- Economic news releases cluster around session opens
Kill Zones (ICT Concept)
- London Kill Zone: 2:00 AM – 5:00 AM ET
- New York Kill Zone: 7:00 AM – 10:00 AM ET
- These windows concentrate institutional order flow and create the highest-probability setups
Session Strategy
- Trade during your best-performing session (check PropTally's session analysis)
- Avoid low-liquidity periods (Asian session lull, late New York)
- Be aware of session transitions — spreads widen and volatility spikes
