DD IFVG [Pro+] (Dodgy)

Introduction
DD IFVG° [Pro+] is an automated charting tool built to track inversion logic after displacement events—specifically when Fair Value Gaps (FVGs) are closed through and act as an inversion gap. The tool adheres to logic taught by DodgyDD and inspired by Inner Circle Trader (ICT) methodology, offering a clean visual interface to support traders studying price behaviour after liquidity sweeps, FVG closures, and delivery to targets.

This indicator does not draw zones or suggest direction. It operates entirely on confirmed price events and produces logic-bound visuals designed for traders who already understand IFVG-based reasoning and seek visual consistency across sessions and Timeframes.

Key Terms and Definitions

• Swing High / Swing Low: A swing high is a local price peak with lower highs on either side. A swing low is a local trough with higher lows on either side. These are used to detect where liquidity may rest and are required for confirming the initial raid condition in the IFVG model.
  
• Liquidity Raid: This occurs when price breaks a prior swing high or low, effectively “sweeping” a level where orders may be clustered. A raid is a required precursor to inversion logic in this model. The tool will not evaluate a potential Fair Value Gap or DD Inversion unless a swing high or low has been taken first.
  
• Fair Value Gap (FVG): A Fair Value Gap is a price imbalance that occurs when a strong move leaves a gap between candles—specifically, when the high of one candle and the low of a later candle do not overlap. FVGs often emerge during displacement and are commonly studied as inefficiencies within a price leg.
  
• DD Inversion: A DD inversion happens when price fully closes through an existing Fair Value Gap after raiding liquidity, suggesting the original imbalance rebalanced, and looks to reverse its original role. For example, when a bearish FVG is closed above after raiding a swing low, it may behave with a change of orderflow (bullish inversion). The tool recognizes IFVGs as “inverted” after a full-body candle closes through the gap post raid.
  
• Displacement: A strong, directional price move—typically with momentum—that leaves a Fair Value Gap behind. Displacement is important in inversion logic, as it creates the context and confidence in comparing and contrasting FVGs and DD Inversions for obvious flips in market behaviour.
  
• DD Line: Once inversion occurs, the tool draws a single horizontal array on the candle's close. It marks the model’s activation level—not a prediction level or a support/resistance zone. It serves as a reference for when model logic is sequentially active.
  
• Opposing Swing: The swing high or low opposite the one that was swept during the initial raid. This becomes the model’s first target for mechanical delivery and is automatically drawn once the DD line is triggered. When price reaches this swing, the model has reached its objective and could offer opportunities for further continuation to additional liquidity pools.
  
• Invalidation: A DD Inversion is considered invalid in one of two scenarios, which the user can toggle individually: a body print back above/below the inversion in bearish/bullish conditions, or trading above/below the most recent swing high/low after the liquidity raid in bearish/bullish conditions. The DD line will continue extending when traded to until the setup is invalidated, or when the Opposing Swing is reached.
  
• Consequent Encroachment (CE): The midpoint (50%) of the FVG or IFVG. This line can be optionally displayed for users who use midpoint reference logic. It is not required by the model’s internal logic but may assist with discretionary interpretation.
  

Description
At its core, DD IFVG° [Pro+] follows a structured three-step logic sequence: a FVG is created, liquidity is taken, and the Fair Value Gap (FVG) inside of the leg of the raid is closed through, signally a potential orderflow shift. Once inversion is confirmed, a DD line is plotted at the close of the candle that caused the inversion, making it the structural anchor for the model.
The tool does not account for partial fills or candle wicks for FVGs or IFVGs. Only full-body closures through a qualifying FVG are recognized. When this occurs, a bullish or bearish inversion is validated and the model becomes active. From there, the opposing swing (the unswept high or low from the displacement leg) is automatically drawn as the target for the IFVG model.
The model remains active until either the opposing swing is tagged (completion) or Invalidation Condition is triggered (close through DD IFVG, or price violating the liquidity raid swing). Upon invalidation, the DD line turns gray, signalling that the structure is no longer valid for ongoing tracking.

Key Features

• The Bias allows traders to define whether to track bullish inversions (closing above bearish FVGs), bearish inversions (closing below bullish FVGs), or neutral for both. This allows isolate directional focus or display all structures on the same chart mechanically.
  
• The Liquidity Timeframe defines the Timeframe for swing highs and lows that are identified for the required liquidity raid. The Chart mode allows analysts to use the active chart Timeframe. Auto enables a custom Timeframe Alignment, explained inside of the setting tooltip. Custom allows for specific frame alignment, which is helpful when syncing with specific higher-Timeframe structure. Session allows the user to use session highs and lows for the liquidity raid. Observe the difference in the DD IFVG's frequency based on different Liquidity Timeframe configurations:
  
  Chart:Automatic:Custom (1H):Session:
• The FVG Filter Timeframe requires the DD setup to trade into a FVG before qualifying the raid filter. For instance, setting this to 4H ensures that only setups that form within a 4-hour FVG. This gives analysts an additional filter to qualify the start of the mechanical model.
  
• Session Filter enables traders to define up to four specific Time blocks when the model is permitted to trigger. The Macros Only toggle filters setups further by limiting activation to the first and last 10 minutes of each hour—a filter inspired for intraday traders and scalpers.
  
• The Invalidation Condition determines when a DD inversion is considered not longer valid. Close will maintain the inversion as active until price prints a body past the DD IFVG. Swing will maintain the inversion as active until the most recent swing from the liquidity raid is traded through; in this case a warning will appear once price prints a candle body past the DD IFVG.
  
• Model Style includes customizable controls for the DD line, the opposing swing marker, and invalidated states. Label appearance, line styles, and extension behaviour are fully user-controlled. Traders can also enable the Consequent Encroachment (CE) line, which marks the 50% midpoint of the FVG and IFVG.
  
• An Info Table is available to display current model state, including user bias, active Timeframes, asset, and Time filter. Its position is fully customizable and can be moved to match chart preferences.
  

How Traders Can Use the Indicator Effectively
DD IFVG° [Pro+] is not meant to identify trade signals, entries, or exits. It is best used as a visual tracker and confluence for structure-based delivery, particularly for those following DodgyDD-style IFVG logic. The tool excels as a companion for:

• Journaling and reviewing IFVG-based setups across Timeframes and sessions
  
• Studying structural completion or invalidation behaviour
  
• Tracking delayed deliveries and retracement-based logic
  

Traders using the tool should be familiar with FVG formation, inversion criteria, and the importance of opposing swing resolution.

Usage Guidance

1. Add DD IFVG° [Pro+] to a TradingView chart. This is a fractal script and can be applied across any Timeframe or asset pairing depending on your session model and preferences.
   
2. Use the DD line to track inversion structure, monitor when inversions are created and negated, and reference the opposing swing to determine whether structural delivery has completed.
   
3. Use the DD IFVG° [Pro+] in combination with your own discretion and narrative to assess when the model has flipped, held, or broken.
