The Interbank Price Delivery Algorithm (IPDA) This indicator automates the visualization of the Interbank Price Delivery Algorithm (IPDA) concepts as taught by ICT. The core principle of IPDA is that the market's price delivery mechanism references specific historical data intervals to create the current market structure. By looking back at the highs and lows of the past 20, 40, and 60 trading days, we can define the key ranges that influence institutional order flow. The ICT-IPDA (Look-Back) indicator not only calculates these standard ranges but expands upon them, providing a comprehensive and fully customizable tool for traders to analyze market structure, identify areas of premium and discount, and anticipate future price movements with greater clarity.
2. Logic
This tool is designed to be both powerful and flexible, automatically calculating and plotting crucial data points based on your selected look-back period.
2.1. Expanded Look-Back Intervals While standard ICT teaching focuses on 20, 40, and 60-day look-backs, this indicator extends the analysis to a much broader spectrum, allowing you to select from:
20, 40, 60 days
80, 100, 120 days
140, 160, 180 days
200, 220, 240 days
This provides a multi-layered view of market structure, suitable for all trading styles from intraday to long-term position trading.
2.2. Comprehensive Range Analysis For each active look-back period, the indicator automatically plots:
Premium & Discount Zones: Visualized as boxes, these zones clearly delineate where prices are considered expensive (Premium) or cheap (Discount) relative to the range's Equilibrium.
Key Levels: The Range High, Low, and Equilibrium (50%) are plotted as distinct lines, serving as critical support, resistance, and pivot points.
Internal Range Structures: To provide a more granular view, the indicator can also plot fractal divisions of the range, including Quadrants (25%), Octants (12.5%), and even Sedecimants (6.25%).
3. Settings & Options
The true power of this indicator lies in its extensive customization options, allowing you to tailor the tool to your exact analytical needs.
3.1. IPDA Ranges & Data Types
Select Look-Backs: Easily toggle any of the 12 available IPDA look-back intervals on or off.
IPDA Data Ranges Type: Choose how the data is calculated and displayed across timeframes.
CLASSIC: The standard daily IPDA Data Ranges, visible only on the 1D timeframe.
CLASSIC+LTF: Plots the daily IPDA Data Ranges (20D, 40D, etc.) on any timeframe, making them accessible for intraday analysis.
LTF: Plots dynamic IPDA ranges based on the last 20, 40, 60, etc. candles of your current, lower timeframe (e.g., the last 20 hours on an H1 chart).
3.2. Anchor & Forward Projection
Anchor Date: Lock the IPDA calculation to a specific start date. This allows you to analyze how price has behaved relative to a fixed, historical range without it updating every day.
Cast Forward: Project any or all of the IPDA levels into the future. This feature helps frame upcoming price action and identify potential future support and resistance zones.
3.3. Visual & Plotting Options
Plot Format: Choose your preferred visualization style: Boxes only, Lines only, a combination of Boxes + Lines, or one of two data Tables.
Table A: Shows a clean table view indicating whether the current price is in a Discount or Premium for each of the 12 IPDA ranges.
Table B: Shows the precise location of the current price as a percentage within each IPDA range.
Complete Styling Control: Customize the colors, line styles (solid, dashed, dotted), and widths for every single visual element, including Premium/Discount boxes, EQ, Quadrants, Octants, and more.
3.4. Labels & Alerts
Pane & Tooltip Labels: Display precise price information on the price scale and in hover tooltips. You can customize the position, style, and content (price, percentage, fraction, decimal) of these labels.
Alerts: Set up custom alerts to be notified when price crosses above or below the High, Low, or Equilibrium of any selected IPDA range.
4. Practical Application & Strategy
4.1. For Intraday Traders: The 20-Day Look-Back is invaluable. It helps identify the immediate operational range, allowing you to spot high-probability trade setups at deep discount or premium levels and target the opposing end of the range or its equilibrium.
4.2 For Swing & Position Traders: The 40, 60, and 80-Day Look-Backs offer a clearer perspective of the broader market bias. These larger ranges define significant levels that are more likely to act as major turning points or trend continuation levels. Use them to understand the macro context before zooming in for entries.
