Liquidity Sweep Reversal EA

Liquidity Sweep Reversal EA

? What is Liquidity Sweep Reversal EA?

Liquidity Sweep Reversal EA is an automated Expert Advisor based on Smart Money Concepts (SMC). It identifies liquidity pools (swing highs and lows) and waits for the price to sweep those levels with a rejection wick, then enters a reversal trade in the opposite direction.

This strategy exploits a well-known institutional behavior: market makers push price beyond obvious support/resistance levels to trigger retail stop losses and collect liquidity, before reversing sharply. The EA detects this moment on the closed bar and enters at the beginning of the reversal.

⚙️ How It Works

Step 1 — Identify Liquidity Levels The EA scans the last N bars (default: 20) and identifies the highest high and lowest low, which represent liquidity pools where stop losses tend to cluster.

Step 2 — Detect the Sweep On each closed bar, the EA checks if the price:

• Swept above the swing high and closed back below it (bearish reversal signal)
• Swept below the swing low and closed back above it (bullish reversal signal)

The wick that performed the sweep must exceed a minimum ATR threshold to filter weak moves.

Step 3 — Enter the Trade A market order is placed at the open of the next bar. Stop Loss is placed beyond the sweep extreme. Take Profit is set at a fixed ATR multiple.

Step 4 — Manage with Trailing Stop Once the trade reaches the activation threshold, an ATR-based trailing stop locks in profits while allowing the position to run during strong reversals.

?️ Risk Management

• Fixed % risk per trade — position size is calculated automatically based on equity and stop loss distance
• ATR-based Stop Loss — adapts to market volatility
• Trailing Stop — protects profits once activated
• Time-based exit — closes trades that do not move within N bars
• Spread filter — avoids entries during high spread conditions
• One position at a time — prevents overexposure
