ICT Order Block Pro

The ICT Order Block Pro indicator is a quantitative trading system that mechanically identifies high-probability Order Blocks (OBs) based on strict Inner Circle Trader (ICT) concepts. It acts as a narrative engine, validating setups only when specific conditions like liquidity sweeps, structural shifts, and session timing are met, while dynamically projecting Draw on Liquidity (DOL) targets.

Usage

The indicator identifies and plots institutional Order Blocks on your chart. To use this tool effectively, look for the following sequence:

• Setup Identification: Monitor the chart for a highlighted Order Block appearing during your active trading sessions (Kill Zones).
• Targeting: Once an OB is validated, the script projects a dashed "Draw on Liquidity" line toward the closest opposing liquidity pool. Use this as your mechanical Take Profit target.
• Execution: Entries are typically taken when price returns to tap the OB box. Stops can be placed outside the box or at the Mean Threshold (50% mark).
• Secondary Entries: If a primary OB fails and price closes through its Mean Threshold, the script can convert it into a Breaker Block, signaling a potential reversal or continuation entry in the opposite direction.

Details

This tool utilizes a multi-step validation process to ensure institutional sponsorship:

• The Purge (Liquidity Sweep): Validates OBs only if they originated from a swing that swept a short-term liquidity pool.
• The Shift (MSS): Requires an aggressive Market Structure Shift via displacement away from the OB.
• Imbalance: Confirms displacement by checking for the presence of a Fair Value Gap (FVG).
• PD Array Alignment: Dynamically calculates dealing ranges to filter for bullish setups in a Discount and bearish setups in a Premium.
• HTF Nesting: Highlights current timeframe OBs that form inside active Higher Timeframe (HTF) blocks for high-confluence "nested" setups.

Settings

[ICT] Global Text & Label Styling

• Show Block Labels?: Toggles the visibility of labels for the identified blocks.
• Text Size / Alignment: Customizes the visual presentation of labels.

[ICT] DOL Targets (BSL / SSL)

• Show Draw on Liquidity Lines: Toggles the projection of mechanical targets.
• 1-2-3 Pivot Length: Adjusts the sensitivity of the pivot algorithm used for liquidity detection.
• Fallback Min R:R Target: Sets a minimum Reward-to-Risk ratio for target projection if structural targets are unavailable.

[ICT] Order Blocks (Current TF)

• High Prob OBs Only: Applies optimized filters to show only the highest probability setups.
• Show OB Mean Threshold (0.5): Displays a midline for the Order Block, often used for refined entry or strict invalidation.
• Direction Filter: Allows filtering for only bullish, only bearish, or both types of blocks.

[ICT] Narrative & Engine Tuning

• Strict Mean Threshold Invalidation: When enabled, the block is invalidated the moment a candle body closes past the 50% mark.
• Require PD Array Alignment: Filters setups based on Premium/Discount zones.
• Require Liquidity Sweep (Purge): Ensures the OB must take out liquidity to be valid.

[ICT] Time & Macros

• Use Kill Zones: Restricts OB detection to specific trading sessions (e.g., NY AM/PM).
• Macro Sessions: Highlights and filters for specific algorithmic "Silver Bullet" windows.

FAQ

How do I access ICT Order Block Pro?

You can get access on the LuxAlgo Library for charting platforms like TradingView, MetaTrader (MT4/MT5), and NinjaTrader for free.

What is the "Mean Threshold" in this script?

The Mean Threshold is the 50% mark of the Order Block. In the ICT methodology, a candle body closing past this level often indicates that the Order Block is no longer valid for support or resistance.

Why do some Order Blocks disappear or change color?

The script includes dynamic conversion. If a standard Order Block is violated but meets specific criteria, it may convert into a Breaker Block or Mitigation Block, shifting from an area of support/resistance to a pivot for the opposite direction.
