The London open is the single most important time of day for forex traders. Here's exactly how to trade it using Smart Money Concepts — with backtested data.
Why the London Open Matters
When London opens at 7:00 AM UTC (2:00 AM EST), institutional volume floods the market. The Asian session has created a range — and London institutions use that range to engineer liquidity sweeps before the real move begins.
What Happens at the London Open:
- Asian range is established — price has been ranging for 6-8 hours
- London institutions enter — massive volume injection
- Judas Swing occurs (68% of the time) — false move that sweeps Asian range
- Real move begins — after the sweep, price moves in the true direction
- FVG and OB form — during the displacement after the sweep
Key Takeaways:
- London open = highest institutional volume of the day for European pairs
- 85% of Asian range highs/lows are swept during London KZ
- The Judas Swing (false move) occurs 68% of the time — don't get trapped
- London KZ FVGs fill 84.4% of the time — highest of any session
The Judas Swing: London's Signature Move
The Judas Swing is a false move that occurs at the London open. Price appears to break out of the Asian range in one direction, triggers stop losses and breakout entries, then reverses sharply in the opposite direction.
How the Judas Swing Works:
- Asian session creates a range (Asian high + Asian low)
- London opens with a push ABOVE the Asian high (or below the Asian low)
- Breakout traders enter long (or short)
- Stop losses above/below the range are triggered
- Price reverses sharply — the Judas Swing is complete
- Real move begins in the opposite direction
Judas Swing Statistics:
| Metric | Value |
|---|---|
| Judas Swing frequency | 68% of London opens |
| Average false move depth | 15-25 pips beyond Asian range |
| Time to reversal | 15-45 minutes |
| Win rate when trading the reversal | 67% |
| Win rate when getting trapped by the false move | 28% |
Key Takeaways:
- The Judas Swing happens 68% of the time at the London open
- It's a false breakout that traps traders before the real move
- If you know to expect it, you can trade the reversal with a 67% win rate
- If you get trapped by it, your win rate drops to 28%
Step-by-Step London Open Strategy
Step 1: Mark the Asian Range
Before London opens, mark:
- Asian session high — the highest price during 11:00 PM - 6:00 AM UTC
- Asian session low — the lowest price during 11:00 PM - 6:00 AM UTC
- Asian range size — the distance between high and low
Step 2: Wait for the London Open (7:00 AM UTC)
Don't trade before London opens. The Asian session is low-volume and unpredictable.
Step 3: Watch for the Sweep (Judas Swing)
- If price pushes ABOVE the Asian high → expect a reversal (bearish Judas Swing)
- If price pushes BELOW the Asian low → expect a reversal (bullish Judas Swing)
- Wait for price to push 5-15 pips beyond the range
- Wait for a rejection candle (long wick)
Step 4: Confirm with CHoCH
After the sweep, look for:
- Bearish CHoCH: Price breaks below a lower-timeframe swing low (after sweeping Asian high)
- Bullish CHoCH: Price breaks above a lower-timeframe swing high (after sweeping Asian low)
Step 5: Enter on FVG Retracement
- Enter at the 50% CE of the FVG formed during the displacement
- Stop loss beyond the sweep wick
- Target: opposing side of the Asian range, then session liquidity pools
Example:
EUR/USD London Open Setup
- Asian high: 1.1640
- Asian low: 1.1620
- London opens: Price pushes to 1.1650 (sweeps Asian high)
- Rejection: Long upper wick on 1.1650 candle
- CHoCH: Price breaks below 1.1635 (M15 swing low)
- FVG: Bearish FVG at 1.1638-1.1645
- 50% CE entry: 1.1641
- Stop loss: 1.1652 (above sweep wick)
- TP1: 1.1620 (Asian low — opposing liquidity)
- TP2: 1.1600 (previous session low)
- TP3: 1.1580 (HTF target)
Risk = 1.1652 - 1.1641 = 11 pips
Reward to TP1 = 1.1641 - 1.1620 = 21 pips (1:1.9)
Reward to TP2 = 1.1641 - 1.1600 = 41 pips (1:3.7)
Key Takeaways:
- Mark the Asian range before London opens
- Wait for the sweep, then the CHoCH, then the FVG
- Enter at the 50% CE — not during the sweep
- Target the opposing side of the Asian range first
