NinjaTrader BOS & CHOCH and FVG Indicator
NinjaTrader BOS & CHOCH and FVG Indicator combines structural analysis with imbalance detection to identify trend continuations and reversals. It integrates BOS, CHoCH, and FVG concepts to highlight key reaction zones. Configurable modes define how FVGs are detected, filled, and maintained, helping traders align structure and liquidity in different market conditions.

What the BOS & CHOCH and FVG Indicator Does
The NinjaTrader BOS & CHOCH and FVG Indicator is a tool based on structural analysis and the study of imbalance zones. It combines three key elements widely used in ICT/SMC methodologies: Break of Structure (BOS), Change of Character (CHoCH), and Fair Value Gap (FVG). This approach focuses on analyzing a sequence of events that form the foundation for structured market analysis.
BOS
Reflects the moment when price breaks a local extremum in the direction of the current impulse. This confirms that momentum is maintained and is interpreted within the methodology as a potential continuation of the current momentum.
CHoCH
Captures a shift in direction when the sequence of highs and lows reverses, allowing early recognition of potential trend-reversal scenarios.
FVG
An area of price imbalance that forms during an impulsive move when price passes through a range too quickly and orders do not fully match. Such zones often become areas to which price returns before continuing its movement. A retracement into an FVG is viewed as a moment when the market compensates for the imbalance and forms a new point of interest.
The BOS & CHOCH and FVG structure follows a logical sequence. First, a structural event appears — either continuation of the impulse or a change in direction. This impulsive move leaves behind an imbalance zone (FVG). Later, the market returns to this area, seeking to compensate for the unfilled volume. Thus, the FVG becomes not just an area of interest, but part of a unified chain: event → consequence → compensation → potential continuation, where each stage is logically connected to the previous one and highlights areas of potentially significant price reactions.
In this indicator, the logic is designed to strictly follow the correct definition of BOS and CHoCH patterns, based on the precise sequence of swing points that indicate a change in market character.
Many similar indicators simplify the logic and interpret BOS and CHoCH as any local breakout, without verifying the necessary swing sequence. This approach ignores the overall market context and the preceding Bullish or Bearish structure, often resulting in false markers.
In this solution, BOS and CHoCH are identified only when the full swing sequence is respected. Each breakout is considered in the context of the complete structure, not as an isolated event. This helps capture changes in market character in line with the complete swing structure.
BOS and CHoCH Identification Rules
| Type BOS / CHoCH | Classic Version | Allowable Deviation |
|---|---|---|
| Bullish BOS | HL → HH → break HH ↑ | HL → HH → HL → break HH ↑ |
| Bearish BOS | LH → LL → break LL ↓ | LH → LL → LH → break LL ↓ |
| Bullish CHoCH | LL → LH → break LH ↑ | LL → LH → HL/LL → break LH ↑ |
| Bearish CHoCH | HH → HL → break HL ↓ | HH → HL → LH/HH → break HL ↓ |
Built-In MFE/MAE Tracker
The indicator includes an MFE/MAE Tracker module that measures how price has moved after each signal — how far it moved in the favorable direction and how far it moved against it, tracked across several configurable holding periods at once.
Results are shown directly on the chart as a dashboard and can be exported to CSV, giving a way to review signal behavior across a large sample rather than relying on visual impression from scrolling the chart. See how the MFE/MAE Tracker is calculated and how to read the dashboard →
How to Interpret and Use the BOS & CHOCH and FVG Indicator
The BOS & CHOCH and FVG Indicator for NinjaTrader combines structure analysis with imbalance detection, helping traders visualize technical areas where price action reflects potential trend continuation or reversal scenarios.
The analytical logic is based on observing how the market transitions through three phases — structure break, imbalance creation, and price retracement.
Bullish BOS + bullish FVG
A bullish BOS reflects trend continuation. When a bullish FVG appears during or after the impulse, traders monitor price retracements into this zone as an area of interest.
Bearish BOS + bearish FVG
A bearish BOS reflects a continuation of downward movement; the next bearish FVG marks an area of interest once price returns to it.
Bullish CHoCH + bullish FVG
In reversal conditions, a bullish CHoCH indicates a structural shift to the upside, and a retracement into a new bullish FVG may be observed as an area of interest.
Bearish CHoCH + bearish FVG
A bearish CHoCH reflects the opposite — the market transitions downward, and the next bearish FVG highlights an area of interest.
FVG Detection Mode
The indicator provides an additional configuration parameter — FVG Detection Mode, which defines how imbalance zones are identified in relation to BOS or CHoCH events:
- After BOS/CHoCH — FVGs are searched only after a confirmed structure shift.
- BOS/CHoCH Impulse — FVGs are found within the impulse that forms BOS or CHoCH.
- Combined — detects both types simultaneously.
BOS/CHoCH Impulse
After BOS/CHoCH
By following this logic, traders can observe how structure breaks create directional bias, how imbalance zones define areas of interest, and how retracements into those zones highlight moments of interest for further analysis. This approach highlights the technical relationship between structure and liquidity, helping to focus on areas of interest where price has historically shown significant reactions based on the selected methodology.
Additionally, to support different trading preferences and analytical approaches, the indicator includes several configuration parameters. The FVG Fill Mode setting defines how a Fair Value Gap is validated — by a simple touch, full fill, or a custom threshold percentage. Traders can also adjust the minimum gap size in price units (ticks or percentages) to filter out minor imbalances, as well as the maximum lifetime of an active FVG zone. These and other parameters allow the indicator to be tailored to individual trading styles and can be reviewed in more detail in the Settings tab.
Indicator Settings & Parameters
Full parameter reference, grouped by configuration area.
| Parameter | Description |
|---|---|
| Market Structure | |
| Swing Strength | Defines the number of bars the indicator considers when identifying local highs and lows based on fractal logic. A higher value increases the strictness of the swing definition, as the extreme must be surrounded by more bars with lower highs (for a top) or higher lows (for a bottom). |
| Show Swing Points | Enables or disables the display of Swing Points on the chart. |
| Enable BoS | Activates the detection of Break of Structure (BOS) on the chart. |
| Enable CHoCH | Activates the detection of Change of Character (CHoCH) on the chart. |
| BoS and CHoCH Confirmation Price Type | Specifies which price type is used to confirm BOS/CHoCH.
|
| FVG Detection | |
| FVG Detection Mode | Defines how the indicator identifies and processes imbalance zones in relation to structural events.
|
| Max Bars To Find FVG | Sets the maximum number of bars after a BOS or CHoCH during which the indicator searches for a valid FVG. This parameter is applicable only in the After BOS/CHoCH and Combined modes. |
| Gap Size Mode | Defines the unit of measurement for the FVG Gap Size, representing the price distance between the candles that form the imbalance.
|
| Minimum Gap Size | Sets the minimum FVG Gap Size according to the selected Gap Size Mode, filtering out minor imbalances that lack trading significance. |
| FVG Mitigation & Lifetime | |
| Mitigated Mode | Determines how a Fair Value Gap is considered filled.
|
| FVG Display Type | Controls how FVGs are displayed on the chart.
|
| Minimum Bars for FVG | Defines the minimum period, measured in bars, during which the FVG remains active and unfilled before being triggered by the selected method — touch, full fill, or threshold percentage. |
| Max FVG Duration | Sets the maximum active lifetime of an FVG. If no touch, full fill, or threshold event occurs within the specified time, the FVG expires. |
| FVG Duration Type | Defines the unit of time used for duration calculation.
|
| FVG Duration in Bars | Sets the numerical duration value corresponding to the selected FVG Duration Type. |
| Alerts | |
| Alerts | Configure various types of alerts. |
