Order Blocks Detector — Supply & Demand Zones
MT5 Indicator | M1 to H1 | Institutional Order Blocks
Automatically detects and draws institutional Order Blocks on the chart. A Bullish Order Block is the last bearish candle before a bullish impulse, representing a Demand Zone where institutional buyers were active. A Bearish Order Block is the last bullish candle before a bearish impulse, representing a Supply Zone where institutional sellers were active.
Bullish OB (Demand Zone): price is likely to bounce upward when it returns to this zone.
Bearish OB (Supply Zone): price is likely to drop downward when it returns to this zone.
A Bullish Order Block is the last bearish candle immediately before a bullish impulse of consecutive candles that breaks above the OB candle's high. A Bearish Order Block is the last bullish candle immediately before a bearish impulse of consecutive candles that breaks below the OB candle's low.
The number of impulse candles required to confirm a valid Order Block is configurable via the ImpulseCandles parameter. A higher value produces fewer but more significant zones. The default value is 6 candles.
Invalidation rule: an Order Block is removed from the chart only when a subsequent candle closes completely beyond the opposite boundary of the block. A wick touching the zone does not invalidate it. Only a candle body closing beyond the boundary does.
Bullish OB invalidated: when a candle closes below the OB Low.
Bearish OB invalidated: when a candle closes above the OB High.
The indicator detects both Bullish and Bearish Order Blocks automatically and draws them as filled rectangles on the chart. Each zone includes a border line at the High and Low, a dotted 50% midline, and a label showing the zone type and pip size.
Only untouched Order Blocks are shown. Zones that have already been visited and closed beyond their boundary are removed automatically. All zones are drawn behind the candles so the chart remains clean and readable.
The indicator scans up to 5000 bars back in history, surfacing older untested zones that may still be structurally relevant. A real-time information panel shows the number of active Bullish and Bearish Order Blocks currently on the chart.
Works on M1, M5, M15, M30 and H1 timeframes. Colors for Bullish and Bearish zones are fully configurable independently.
