What is the ICT Trading Double Purge (Double Liquidity Sweep) Theory

This ICT Trading Strategy called the Double Purge or Double Liquidity Sweep is a specific occurrence in price action where both buyers and sellers are manipulated before the real market move occurs.

This ICT Trading Strategy involves Liquidity sweeps that clear both buy-side and sell-side participants, leading to low-resistance liquidity runs and the formation of true PD Arrays. Key points to consider:

• Markets often reverse after both buyers and sellers are purged.
• Post-Double Purge, true order blocks, breaker Blocks, and Fair Value Gaps (FVGs) form.
• This tool is invaluable for identifying protected highs/lows and building narratives for trade setups.

Why Incorporate the Double Purge in Your Toolbox?

1. Market Profiling: The Double Purge (double Liquidity sweep) aids in identifying whether a market is bullish, bearish, or consolidating. Traders should avoid participating in consolidating markets.

2. High-Probability Zones: The Double Purge often occurs at high-timeframe key levels. It creates continuation patterns aligned with higher timeframe liquidity and order flow.

3. Liquidity Manipulation in the form of a Liquidity Sweep: The market reverses or moves aggressively after liquidity sweeps. Identifying these sweeps allows traders to capitalize on high probability moves.

Double Purge Theory in Bullish and Bearish Markets

Bullish Market: The market runs buy side liquidity (closes above specific highs), then sweeps sell side Liquidity from the low that broke the high, rejecting it.

Bearish Market: The market runs sell side liquidity (closes below specific lows), then sweeps buy-side liquidity from the high that broke the low, rejecting it.

Three Key Formations of the Double Purge

1. The Classic Market Structure Trap

The market creates higher highs and higher lows (or lower lows and lower highs). Break of Structure occurs to cause a Liquidity Sweep on both sides, creating protected highs/lows post-purge.

2. The One Candle Purge

A single candle causes Liquidity Sweeps on both the Swing high and swing low of a range. For validity, the candle must close within both ends of the range.

3. The AMD Purge (Accumulation, Manipulation (Liquidity Sweep), Distribution)

The market accumulates; Liquidity Sweeps occur on both sides and then move aggressively in one direction.

Application of the Double Purge

1. High Timeframe Analysis: Start with a high-timeframe key level (e.g., 4H, Daily). Identify a range (high-to-low or low-to-high). Look for a Double Purge within this range on a lower timeframe to confirm continuation.

2. Continuation Trades: Focus on trades in the direction of high-timeframe liquidity and order flow. Post-purge movements often exhibit high momentum and low resistance.

3. Protected Swing high and swing low: After a Double Purge, the Swing high and Swing low that remains unbroken act as protected levels. These levels become key zones for future trades.

Practical Examples (Double Liquidity Sweep Example)

Classic Market Structure Trap

1. Identify order flow. Before you are going to look for a double purge (Liquidity sweep), you need to look at the current order flow: is it bullish or bearish? In the example on the left we can see that we are clearly in bullish order flow since we are creating new highs and lows.

2. Wait for the double purge. Since we are bullish, you want to see a run on buy side liquidity followed by a run on sell side liquidity.

3. LRLR to the opposite side. After the double purge we will see a low resistance liquidity run towards the opposite side of the range. In the example, we can see that we took out buy stops, followed up by taking out the sell stops. When the sell stops were taken, we saw an aggressive move towards the other side of the range.

One Candle Purge

1. Run on both sides. With one candle purge, one singular candle runs out buyside liquidity and sell side liquidity. In the example on the left, you can see that we ran out buy stops, after that we took out sell stops. Now we should anticipate an explosive move towards buy side again.

2. LRLR to the opposite side. After the one candle purge, we can see that we had an explosive move towards the opposite side of the range again.

AMD Purge

1. Accumulation phase. With an AMD purge you will see that price runs liquidity on both sides during a period of accumulation. In the example below you can see a run on buyside first, followed by a run on the sell side.

2. Aggressive move towards the other side. After both sides of the market are knocked out you should anticipate a move towards the opposite side of the range, as you can see in the example below.

Hints for Optimal Use

• Timing Matters: Double Purges at key times (e.g., during high-impact news events like CPI or NFP) often lead to significant moves.
• Key Levels: Always align purges with premium/discount zones and key PDAs.
• Fractal Nature: Double Purges occur across timeframes; validate setups using a multi-timeframe approach.

Conclusion

The Double Purge Theory provides traders with a robust framework to understand and anticipate market moves. By mastering its concepts, traders can better profile markets, identify liquidity manipulation, and position themselves for high-probability trades.
