Inversion Fair Value Gaps [iFVG] (Zeiierman)█ Overview
Inversion Fair Value Gaps (Zeiierman) identifies when traditional Fair Value Gaps (FVGs) fail and transition into powerful inversion zones.
A regular Fair Value Gap represents an imbalance where price moved aggressively in one direction, leaving behind inefficient trading. While many traders expect these gaps to act as support or resistance, not every imbalance survives. Some are broken, absorbed, and eventually become areas where the opposite side of the market gains control.
This indicator continuously tracks every valid bullish and bearish FVG. When price successfully closes through an existing FVG and later forms an opposing FVG within the user-defined pairing window, the overlapping imbalance is converted into an Inversion Fair Value Gap (iFVG).
Rather than treating every FVG equally, the indicator focuses on failed imbalances that demonstrate a genuine shift in market order flow.
⚪ FVG Detection
The indicator continuously scans price using the classic three-candle Fair Value Gap model.
A Bullish FVG forms when:
• Price leaves an upside imbalance.
• The third candle creates a gap above the first candle.
A Bearish FVG forms when:
• Price leaves a downside imbalance.
• The third candle creates a gap below the first candle.
Unlike many FVG indicators, every detected gap remains internally tracked so it can later evolve into an inversion.
⚪ Inversion Fair Value Gap Detection
Once an FVG is created, it enters an internal memory system.
If price later closes completely through that imbalance, the FVG is considered broken. Rather than immediately discarding it, the indicator temporarily remembers the remaining imbalance.
If an opposing FVG forms before the memory expires, both structures are combined into a new Inversion Fair Value Gap.
Bullish iFVG
• Bearish FVG is broken.
• Bullish FVG forms shortly afterwards.
• The overlapping imbalance becomes bullish support.
Bearish iFVG
• Bullish FVG is broken.
• Bearish FVG forms shortly afterwards.
• The overlapping imbalance becomes bearish resistance.
This process filters out many ordinary FVGs and highlights only those that demonstrate a meaningful transition in buying or selling pressure.
█ How It Works
⚪ Fair Value Gap Detection
The script continuously searches for valid bullish and bearish three-candle imbalances.
Each detected FVG is validated using:
• Minimum gap size.
• Optional fractal confirmation.
• ATR-based filtering.
Only valid gaps enter the internal tracking system.
bullGap = bullW or bullB
bearGap = bearW or bearB
bullValid = bullGap and bullSz >= gapAtr * minGap
bearValid = bearGap and bearSz >= gapAtr * minGap
⚪ Memory & Inversion Detection
Every valid FVG is stored until one of two events occurs:
• Price never breaks the gap, and it eventually expires.
• Price breaks the gap and an opposing FVG forms before the pairing window ends.
When both conditions are satisfied, the overlapping imbalance becomes a confirmed iFVG. This allows the indicator to detect genuine reversals rather than simply highlighting every imbalance.
⚪ Zone Management
Each zone continuously updates its internal state.
A zone may transition through several stages:
• Active
• Tested
• Mitigated
• Frozen
• Removed
Depending on user settings, mitigated zones can either disappear or remain on the chart as historical context.
⚪ Dynamic Zone Merging
Nearby live zones of the same direction can optionally be merged into a single visual area. This reduces chart clutter while preserving the original internal detection logic. The merged display affects visualization only.
⚪ Distance Filtering
Charts containing hundreds of historical zones can quickly become difficult to read.
The indicator can automatically hide zones that are farther than a user-defined ATR distance from the current price. Hidden zones continue to exist internally and become visible again if price returns. This improves chart clarity without affecting detection, memory, or alerts.
█ How to Use
⚪ Bullish iFVG Retest
After a bullish iFVG forms, price retraces back into the inversion zone before finding support and continuing higher.
Rather than chasing the initial breakout, traders can wait for the retest and look for long confirmation as price reacts from the bullish iFVG.
⚪ Bearish iFVG Retest
After a bearish iFVG forms, price retraces back into the inversion zone before finding resistance and continuing lower.
Instead of entering during the initial breakdown, traders can wait for the retest and look for short confirmation as price reacts from the bearish iFVG.

Smart Gap Concepts [MarkitTick]💡 This indicator automates the identification and classification of price gaps, commonly known as Fair Value Gaps (FVG) or Imbalances, by integrating market structure and volume analysis. Unlike standard gap detectors that simply highlight empty space on a chart, this script applies algorithmic filters to categorize gaps into three distinct phases of market movement: Breakaway, Runaway, and Exhaustion. This helps traders understand the potential context of a move rather than just seeing a support or resistance zone.
● Originality and Utility
The primary innovation of this tool is its dynamic classification system. It moves beyond visual detection by checking the "why" behind the gap. By referencing Swing Highs and Swing Lows (Market Structure) alongside Volume efficiency, it determines if a gap represents a breakout, a trend continuation, or a climatic end to a move. Additionally, the script features an automated mitigation tracking system that removes gaps from the chart once price has re-tested the midpoint, ensuring the visual workspace remains clean and relevant to current price action.
● Methodology
The script operates on a multi-stage logic engine:
• Gap Detection
It first identifies the core imbalance where the Low of the current bar does not overlap with the High of the bar two periods prior (for bullish gaps), ensuring the intervening candle represents a strong displacement.
• Structural Analysis (Breakaway Gaps)
The script monitors Pivot Highs and Lows. If a gap occurs simultaneously with a close beyond a key structural Pivot, it is classified as a "Breakaway Gap." This signals the potential start of a new trend.
• Volume and Time Analysis (Exhaustion Gaps)
To identify potential reversals, the script looks for "Trend Maturity." If a gap forms after a long duration since the last pivot and is accompanied by a volume spike (defined by the Volume Spike Multiplier), it is labeled as an "Exhaustion Gap."
• Continuation (Runaway Gaps)
If a gap is valid but meets neither the Breakaway nor Exhaustion criteria, it is considered a "Runaway Gap," typically found in the middle of an established trend.
• Dynamic Cleanup
The script tracks the midpoint of every active gap. If price creates a lower low (for bullish gaps) or higher high (for bearish gaps) beyond this midpoint, the gap is considered mitigated and is removed from the screen.
📖 How to Use
Traders can utilize the color-coded classifications to gauge market intent:
Breakaway (Default Blue): Watch these zones for potential trend initiations. These are often high-probability areas for a retest entry after a structure break.
Runaway (Default Orange): These indicate strong momentum. They can be used to trail stop-losses or add to winning positions, as price should ideally not close below these gaps in a healthy trend.
Exhaustion (Default Red): Be cautious when these appear. They suggest the current move is overextended and a reversal or complex pullback may be imminent.
• Exhaustion Gap : A Practical Case Study
• Breakaway Gap: A Practical Case Study
• Runaway Gap : A Practical Case Study
⚙️ Inputs and Settings
Min Gap Size (Points): Filters out insignificant gaps smaller than this threshold.
Structure Lookback: Defines the sensitivity of the Pivot detection (Swing High/Low).
Volume Avg Length & Multiplier: Determines what qualifies as a "Volume Spike" for exhaustion logic.
Trend Maturity: The minimum number of bars required to consider a trend "old" enough for an exhaustion signal.
Visual Settings: Custom colors for each gap type and box extension length.

Gap Statistics (Zeiierman)█ Overview
The Gap Statistics (Zeiierman) indicator is crafted to monitor, analyze, and visually present price gaps on a trading chart. Price gaps are areas on a chart where the price jumps up or down from the previous close to the next open, creating a "gap" in the normal price pattern. This script delivers an extensive range of statistics related to these gaps, encompassing their size, direction (whether bullish or bearish), frequency of getting filled, as well as the average number of bars it takes for a gap to be filled. The indicator also visually represents the gaps, making it easier for traders to spot and analyze them.
█ How It Works
Gap Identification: The script identifies gaps by comparing the open price of a bar to the close price of the previous bar. If there is a discrepancy between the two, it is recognized as a gap.
Gap Classification: Once a gap is identified, it is classified based on its size (as a percentage of the previous close price) and direction (bullish or bearish). The gap is then added to a specific category based on its size.
Gap Tracking: The script keeps track of all identified gaps using arrays and user-defined types, storing details like their size, direction, and whether they have been filled.
Gap Filling: The script continuously monitors the price to check if any previously identified gaps get filled. A gap is considered filled if the price moves back into the gap area.
Statistics and Alerts: The script calculates various statistics like the total number of gaps, the number of filled gaps, the average number of bars it takes for a gap to fill, and the percentage of gaps that get filled. It also generates alerts when a new gap is identified or an existing gap gets filled.
█ How to Use
Gaps are often classified into four main types:
Common Gaps: These are not associated with any major news and are likely to get filled quickly.
Breakaway Gaps: These occur at the end of a price pattern and signal the beginning of a new trend.
Runaway Gaps: Also known as continuation gaps, these occur in the middle of a trend and signal a surge in interest in the stock.
Exhaustion Gaps: These occur near the end of a price pattern and signal a final attempt to hit new highs or lows.
The Gap Statistics (Zeiierman) indicator enhances a trader's ability to use gaps in their trading strategy in several ways:
Statistical Analysis: Traders get comprehensive statistics on gaps, such as their size, direction, and how often they get filled.
Performance Tracking: The indicator tracks how many bars it typically takes for a gap to fill, providing traders with an average timeframe for gap closure.
█ Settings
Display Gaps: Choose to display "All Gaps," "Active Gaps," or "None."
Show Gap Size: Toggle on/off the display of the gap size.

- Zones: +shows gaps as dynamic horiz zones
KGB Hunter Pro Gap Exterminator focuses on showing you all possible types of gaps in multiple colors. Gap theory states that price tends to return and fill the gaps,
so you can use it to collect the bounty. You can apply any combination of complex filters to narrow down search results i.e., find only all:
- type 3 gaps up with allowed wick-candle overlapping of up to 10% and
- gap size larger than 200 and
- with at least one of the candles larger than 100 and
- volume change at least 40 and
- spanning less than 2 bar periods and
- excluding weekend gaps
Features:
- highlights gaps using barcolor and plotchar chars (8 colors x 2 dirs)
- supports all 3 types of gap overlapping: full gap (no overlapping), wick-wick and wick-body overlapping up to a specified % of candle body
- finds all types of gaps with pro filters for price, time, large, volume, timerange, candle size, doji gaps
- individual show/hide flags for each gap/char based on gap type
- can show/hide gaps/chars based on gap dir
- changes color of gaps/chars based on gap dir/type, multi color gap type combos
- displays chars above/below bar based on gap dir
- can show/hide weekend gaps
- counts all filtered gaps
Colors:
Basically There are 2 gap types (Price, Time) x 2 directions (Up, Down) x 2 modifiers (Large, Volume), Volume Gap is a separate class with its own modifiers, so more accurately:
- (Price, Time) x 2 directions (Up, Down) x Large modifier
- (Price Volume, Time Volume) x 2 directions (Up, Down) x Large modifier
using a total of 16+1 colors or 8+1 base colors + transparency modifier
depending on settings you can highlight gaps using any multi color combo from just 1 to all 16 colors (+1 gray color for weekends).
basic gap = 1 base color with normal transparency
price,time = 2 base colors (including basic gap) with normal transparency (+1 color)
* up,down dir = +2 new base colors with normal transparency (including 2 base colors), with a total of 2*2 = 4 price/time base colors (+2 colors)
* large = same 4 base colors with vivid transparency modifier (+4 colors)
* volume = +2 new base colors with normal transparency, a separate class (+2 colors)
* volume * up,down dir = +another 2 new base colors with normal transparency (including 2 volume base colors), with a total of 2*2 = 4 volume base colors (+2 colors)
* volume * large = 4 volume base colors with vivid transparency modifier (+4 colors)
weekend_gap = gray (+1 color)
doji gap, candle gap, timerange gap = no special color, inherits color from parent gap type
for more details, please see the Gap Color Hierarchy comments in code
_________________________________________________________________________
You can find the following gap related terminology in literature: full, partial, extreme, breakaway, runaway/continuation, common, exhaustion gaps.
There are no exact rules to distinguish between them, so this can't be implemented.
When defining a gap it all boils down to how do you plot a gap, which points between adjacent candles do you consider a gap. Different sources apply different methodology
but in practice only 3 types of gap overlapping can exist:
- full gap (no overlapping),
- partial (wick-wick overlapping) and
- extreme partial (wick-body overlapping up to a specified % of a candle body)
All these types are supported in this script. The only possible remaining option is candle-candle overlapping which is not a gap by definition.
Many other script specific subtypes are also supported. Please see description of each gap type below and comments in code.
General display modes
- gap has 3 possible overlapping modes: full gap (no overlapping), wick-wick overlapping, wick-candle overlapping up to a specified % of candle body size (for mode 3 only)
the remaining candle-candle overlapping implies not a gap by definition
full gap mode will find the least amount of gaps, wick-candle - the most
- gap can be either price or time, up or down, and shown above or below the candles (gap chars)
- by definition, a price gap is a smaller subset of a time gap, a gap within current session with a price gap and zero time lag between bars.
Therefore timerange filter is useless for price gaps, but can still be applied.
On the other hand, all price gap filters can be applied to time gaps without any distinction.
- gap can have multiple modifier subtypes: (price|time) * (up|down) * (large? + volume? + doji? + timerange? + weekend?)
i.e. price + large + volume + doji or time + large + volume + timerange + doji + weekend
- the gap is always counted only once no matter how many subtype modifiers it has
- if the gap does not satisfy any of the applied flags/filters it is not shown/counted (no gap bars/chars are shown)
- gap color can depend on a combo of gap type/dir and modifier subtypes or can be shown in a single base color
- char color can only depend on gap dir (not type/modifiers) or can be shown in a single base color
- char position can also depend on gap dir (above/below) the gap candle. Alternatively you can pin chars to the top/bottom of the screen in UI Styles.
- change_by_type = true - uses gap type base colors (2 colors + optional modifiers, up to 8 colors if volume and/or large filters are enabled)
- change_by_dir = true - uses gap dir base colors (2 colors + optional modifiers, up to 8 colors if volume and/or large filters are enabled)
- both change_by_type and change_by_dir = true - uses both gap type and dir base colors (4 colors + optional modifiers, up to 16 colors if volume and/or large filters are enabled)
- both change_by_type and change_by_dir = false - uses a single base gap color (1 color)
- don't need that much colors - disable filters
- highlight bars has priority over individual gap flags, when it is false all gaps are hidden regardless of their corresponding flag settings (does not affect dim weekend gaps)
- show chars has priority over individual gap char flags, when it is false all char flags are hidden regardless of their corresponding flag settings
- price gaps are only shown/counted when show_price_gaps flag is true. The large or volume filters can be used to narrow down results further.
- time gaps are only shown/counted when show_time_gaps flag is true. The large, volume, and timerange filters can be used to narrow down results further.
- doji gaps are only shown/counted when show_doji_gaps flag is true. The doji candle size and other filters can be used to narrow down results further.
- show weekend gaps = true and dim weekend gaps = false - shows/counts weekend gaps
- show weekend gaps = true and dim weekend gaps = true - dims weekend gaps, doesn't show/count weekwend gaps
- show/dim weekend gaps do just that - show the gap if it happens on a weekend, not all weekends
- large gaps are only shown/counted when the large filter is enabled != 0. positive values 5 (>= 5), negative -5 (<=5) are used to switch between <>
- volume gaps are only shown/counted when the volume filter is enabled != 0. positive values 5 (>= 5), negative -5 (<=5) are used to switch between <>
- timerange gaps are only shown/counted when the timerange filter is enabled != 0. positive values 5 (>= 5), negative -5 (<=5) are used to switch between <>
- candle size gaps are only shown/counted when the candle size filter is enabled != 0. positive values 5 (>= 5), negative -5 (<=5) are used to switch between <>
- candle size filter is the only filter with 2 arguments, use_and_for_delta to enable AND condition for the args (OR is the default)
