Kill Zones are specific time windows within sessions where institutional traders (banks, hedge funds, market makers) are most active. These periods consistently show: • Highest win-rate setups • Largest moves relative to risk • Best liquidity for entries/exits • Most reliable technical patterns Popularized by ICT (Inner Circle Trader), these zones represent when smart money acts.

Target: Opposite side of range or session high/low Best Pairs: EUR/USD, GBP/USD, EUR/GBP, Gold NY Kill Zone (08:30-11:00 EST) Why It Works: • Overlaps with London session (maximum volume) • Economic data releases at 08:30 • US institutions enter positions • Highest liquidity period globally How To Trade: 1.
