OB Scalper Pro MT5 — Multi-Symbol Order Blocks Scanner & Trader

OB Scalper Pro is a fully automated multi-currency algorithmic trading system based on institutional Smart Money Concepts (SMC) and Order Block mechanics.

The Expert Advisor operates directly from a single chart, continuously scanning all selected symbols from your Market Watch in the background. It identifies high-probability supply and demand order blocks, validates setups with Fair Value Gap (FVG) analysis, and executes fast trades with precision risk management and dynamic ATR-based position tracking.

Core Trading Strategy

1. Fractal-Based Institutional Zones:
The algorithm continuously monitors price action using 3-bar fractal swing structures to identify critical market pivot highs and lows.

2. Order Block Formation:
When price breaks through an established fractal level, the system identifies the last institutional buying candle before a downward move (Bearish Order Block / Supply Zone) or the last institutional selling candle before an upward move (Bullish Order Block / Demand Zone).

3. Fair Value Gap (FVG) Validation:
An optional algorithmic imbalance filter checks for price displacement gaps within adjacent candles to ensure institutional liquidity participation before qualifying a zone.

4. Retest and Momentum Execution:
Trades are opened when price returns to test active, unmitigated Order Blocks. Protective Stop Loss orders are placed beyond the zone boundaries with configurable buffer margins.

5. Dynamic Exit and Management:
Positions are actively managed via an equity-scaled profit target, dynamic ATR trailing stops, optional partial take profits, and an emergency exit rule that closes open positions if an opposite market structure forms.
