ZoneBlockX — Smart Order Block Detector for MetaTrader 5

ZoneBlockX is a professional-grade supply and demand zone indicator for MetaTrader 5, built on the concept of Order Block detection. It automatically identifies high-probability reversal areas on the chart by locating institutional-style price zones where significant buying or selling activity has previously occurred. Designed for traders who rely on price action and market structure, ZoneBlockX provides a structured and objective view of active zones across any symbol and timeframe.

How It Works

ZoneBlockX scans historical price data to detect two types of zones:

Bull Zones (Demand) A Bull Zone is identified from a bearish candle that is followed by a series of bullish confirmation candles, where at least one confirmation candle's high exceeds the origin candle's open price. This structure indicates that institutional buyers absorbed selling pressure at that level, making it a potential demand area for future price reactions.

Bear Zones (Supply) A Bear Zone is identified from a bullish candle that is followed by a series of bearish confirmation candles, where at least one confirmation candle's low falls below the origin candle's open price. This signals that institutional sellers stepped in at that price level, making it a potential supply area for future rejections.

The number of required confirmation candles is configurable via the OB Strength parameter, giving traders control over how strict the detection criteria should be.

Once detected, each zone is evaluated for mitigation. A zone is considered mitigated (invalidated) when price closes beyond the zone boundary — below the low for Bull Zones, or above the high for Bear Zones. Mitigated zones are marked with an "INVALID - Close / SL" label in gray and can be optionally displayed in a faded, dotted style for reference, or hidden entirely to keep the chart clean.

Zone Strength Classification

Each active zone is ranked using a percentile-based classification system relative to all other active zones on the chart:

• Strong Buy / Strong Sell — Top 34% of zones by size. Highest probability institutional levels.
• Better Buy / Better Sell — Middle 33% of zones. Solid levels with above-average relevance.

Only Strong and Better zones are rendered on the chart, keeping the visual output focused on the most significant levels.

Overlap Filtering

When two zones overlap in price, ZoneBlockX applies an automatic conflict resolution system. If one zone is active and the other is mitigated, the mitigated zone is discarded. If both zones share the same mitigation status, the larger zone takes priority and the smaller one is removed. This ensures the chart displays only the most relevant, non-redundant levels at any given time.

Market Bias Engine

ZoneBlockX includes a built-in bias engine that compares the number of active Strong Buy zones against active Strong Sell zones to determine directional sentiment:

• Bullish — Strong Bull count exceeds Strong Bear count.
• Bearish — Strong Bear count exceeds Strong Bull count.
• Neutral — Both sides are equal.

Information Panel

A fully integrated on-chart panel displays all key data in real time, organized into six sections:

• Market Info — Symbol, timeframe, current price, server time, and scan range.
• Zone Bias — Current directional bias with a visual bull/bear ratio bar.
• In Zone — Indicates whether the current price is inside an active Bull or Bear zone, and displays the zone's strength label.
• Bull Zones — Count of Strong Buy and Better Buy zones; average zone size in points; nearest active demand zone price range, distance in points, and zone age in bars.
• Bear Zones — Count of Strong Sell and Better Sell zones; average zone size in points; nearest active supply zone price range, distance in points, and zone age in bars.
• Invalid Zones — Count of mitigated Bull and Bear zones, plus overall mitigation rate as a percentage of all detected zones.

The panel position, background color, and text color are fully customizable.

Alert System

ZoneBlockX supports three types of alerts that can be enabled independently: pop-up alerts, email alerts, and push notification alerts. Alerts fire only once per zone and are suppressed on initial chart load to prevent spam.

ZoneBlockX is built for traders who need a clean, objective, and reliable way to identify institutional price zones without manual drawing. It combines systematic detection, configurable confirmation criteria, percentile-based strength classification, overlap filtering, real-time proximity and age statistics, and an in-zone detection system — all in a single indicator with minimal chart noise and maximum clarity.
