Trend Fair Value Gap Delta Multi TF Scanner - Understanding the Logic and How to Use It
1. Introducing Trend Fair Value Gap Delta Multi TF Scanner
Trend Fair Value Gap Delta Multi TF Scanner combines an MA- and ATR-based trend line with Fair Value Gap (FVG) zones. In addition to marking price gaps, the indicator tracks each zone's state and identifies Buy/Sell reactions when price returns to an eligible zone and then exits it.
Information appears directly on the chart: trend lines, volatility bands, FVG zones, estimated Buy/Sell Volume percentages, and symbols that distinguish trend changes from price-reaction signals.
The indicator supports Scanner and Multi-TF, allowing you to monitor multiple symbols and timeframes before focusing on charts that deserve closer attention. Later sections explain how to combine these features with the indicator's logic.

2. Understanding the Logic and Reading the Indicator
2.1. Identifying the Chart Components
Components reflect the current settings; you can customize their display.
| Component | How to Read It |
|---|---|
| Uptrend line | Displayed while the system maintains a bullish trend state; the lower band serves as the active line. |
| Downtrend line | Displayed while the system maintains a bearish trend state; the upper band serves as the active line. |
| Upper / Lower Band | Two bands around the MA basis line, with their distance determined by ATR. Under the current settings, they appear as dashed lines. |
| MA basis line | The MA used as the calculation basis. Its display is disabled by default. |
| FVG zone | A price box with two boundaries fixed when it forms; its horizontal length can continue to extend while the zone remains active. |
| Buy / Sell Signal | Arrows marking a qualifying price reaction after price touches an eligible FVG zone. |
| Bullish / Bearish Dot | Dots marking changes in the trend state; their meaning differs from Buy/Sell arrows. |
| Buy / Sell Volume | Two percentages inside the zone showing the estimated distribution for the middle candle of the FVG structure. |
2.2. How Is the Trend Determined?
The indicator starts with an MA basis line and places two bands at an ATR-based distance from it. ATR measures price volatility. Under the current settings, the MA uses a period of 20, the SMA method, and the closing price; the bands use a 50-period ATR with a multiplier of 2.0.
Upper Band = MA basis + ATR × Band Multiplier
Lower Band = MA basis − ATR × Band Multiplier
When price crosses above the upper band according to the state-change condition, the system turns bullish. A corresponding break below the lower band turns it bearish. If no new state-change condition occurs, the previous state is retained. A downward price move during a bullish state therefore does not necessarily turn the trend line bearish.
Bullish Dot marks a change from bearish to bullish, while Bearish Dot marks a change from bullish to bearish. These dots help identify a change in context; they do not use the same conditions as signals generated when price touches and bounces out of an FVG.
MA Length, MA Method, Applied Price adjust the calculation basis. ATR Length and Band Multiplier adjust the bands. MA Applied Volume (VWMA) selects the volume source when the VWMA method is used.
2.3. How an FVG Forms from Three Candles
Label three consecutive candles in chronological order as A → B → C, where C is the latest candle being evaluated. The indicator looks for a gap between the price ranges of A and C:
Bullish FVG
The low of candle C is above the high of candle A. The FVG extends from A's high to C's low.
The zone represents a price interval where the ranges of the two outer candles do not overlap.
Bearish FVG
The high of candle C is below the low of candle A. The FVG extends from C's high to A's low.
This is the downward counterpart of the Bullish FVG condition.
The gap condition is the initial identification step. A zone is created only if it also passes the enabled FVG filters. As a result, the indicator does not retain every gap visible on the chart.
2.4. Buy/Sell Volume and the Meaning of Delta
For each FVG, the indicator uses candle B — the middle candle of the three-candle structure to estimate the Buy/Sell Volume distribution. The closer candle B closes to its high, the larger the estimated Buy percentage; the closer it closes to its low, the larger the estimated Sell percentage.
When the data is valid, the two percentages are normalized to total 100%. If the candle has no price range or its volume is invalid for this calculation, the indicator uses a neutral distribution of 50% / 50%. The volume source is selected through FVG Applied Volume, independently of the volume setting used for the MA.
Interpreting these percentages correctly: this is an estimated distribution based on where the candle closes within its range, rather than a direct count of trades executed at the Bid/Ask. The percentages describe candle B when the zone forms, not the total volume accumulated across all subsequent returns to the zone.
For example, 70% Buy and 30% Sell indicate a larger estimated Buy share in that candle. This relationship adds context when examining an FVG. The indicator's Buy/Sell conditions still depend on price reactions and zone eligibility; they do not inherently require the Buy percentage to exceed the Sell percentage, or vice versa.
2.5. Filters for Selecting Zones and Limiting Their Active Lifetime
Settings directly related to FVG creation and management.
| Setting | Current Default | Effect |
|---|---|---|
| Create FVG only in the current trend direction | Enabled | Creates Bullish FVGs only in a bullish state and Bearish FVGs only in a bearish state. Disable this option to evaluate both zone types using the gap condition without requiring alignment with the trend. |
| Filter FVG creation by minimum width | Enabled | Retains only zones that meet the minimum width under the selected mode. |
| Minimum FVG width mode | ATR (200) | The default threshold is 0.2 × ATR(200). If you switch to Points, the corresponding default threshold is 100 points for the symbol being evaluated. |
| Freeze FVG after maximum age | Enabled | Stops updating a zone once it exceeds the maximum age, retaining its last valid drawing. |
| Maximum active FVG age (bars since creation) | 100 bars | The creation candle has age 0. The zone remains eligible through age 100 and freezes from age 101 when the age filter is enabled. |
The ATR(200) used for the width filter has its own fixed period, separate from the ATR Length used for the bands. Direction and width are checked when an FVG is created; they are not additional conditions that must be checked again every time price bounces out of an existing zone.
2.6. When Does a Zone Stay Active or Stop?
| State | Condition and Meaning |
|---|---|
| Active | The zone remains eligible for updates and price-reaction evaluation. A touch alone does not mean the zone has ended. |
| Mitigated | Price penetrates below the bottom of a Bullish FVG or above the top of a Bearish FVG. Merely touching the boundary is not enough. The zone stops being active and switches to the mitigated color; its volume-percentage boxes are hidden. |
| Locked by band | The lower band reaches or rises above the bottom of a Bullish FVG, or the upper band reaches or falls below the top of a Bearish FVG. The zone stops updating and is no longer evaluated for Buy/Sell signals. This differs from price penetrating the zone. |
| Beyond Maximum Age | The zone retains its last drawing and is no longer evaluated for zone signals or alerts. Expiration is not treated as mitigation or a band-lock event. |
A locked zone is no longer processed as an active zone, even if its drawing remains on the chart. Retaining older zones helps with historical observation; their display remains subject to the indicator's storage limits.
2.7. Buy/Sell Signals Follow a Reaction to a Zone Touch
A newly formed FVG is not itself a Buy/Sell signal. The indicator evaluates reactions on candles after the zone's creation candle, while the zone is still active, unmitigated, unlocked, and within the applicable maximum age.
Buy Signal
Price has touched or entered a Bullish FVG without penetrating its bottom, then closes above the top of the zone. On the forming candle, the indicator uses the current price to evaluate the exit condition.
Sell Signal
Price has touched or entered a Bearish FVG without penetrating its top, then closes below the bottom of the zone. Evaluation on the forming candle follows the corresponding Sell-side conditions.
The touch and exit can occur within the same candle or across several candles. Touching the boundary counts as a touch; to confirm an exit, price must move beyond the relevant boundary, rather than merely equal it.
Each touch–exit cycle generates a signal only on its first exit. After a signal, the zone becomes ready for another cycle only when a candle closes back inside the zone, including on its boundary. A wick that returns to the zone while the candle closes outside it does not by itself rearm the cycle.
Minimum FVG age for Buy/Sell defaults to 3 bars, with the creation candle counted as age 0. Values greater than 1 set the minimum age for Buy/Sell signals; values of 1 or less disable this filter. The indicator still does not generate Buy/Sell signals on the FVG creation candle.
If an exit occurs too early and is blocked by the age filter, the indicator does not generate a catch-up signal simply because the zone later reaches the required age. A valid rearming cycle, as described above, is needed.
Distinguish forming-candle signals from closed-candle signals: Buy/Sell signals and trend-change dots update on the forming candle and can change as price continues to move. A provisional FVG on the forming candle can also disappear if its creation conditions are no longer met.
2.8. Alerts for Tracking Different Events
The settings include 12 alert types, covering six event groups in their bullish/bearish directions:
| Group | What to Distinguish |
|---|---|
| Buy / Sell | A touch followed by an exit from an eligible zone. |
| Bullish / Bearish Dot | A change in the trend state. |
| New bullish / bearish FVG | A newly formed eligible FVG, rather than a bounce signal. |
| FVG first touch | The first touch after the zone's creation candle while the zone remains eligible. Price does not have to bounce out first. |
| FVG mitigated | Price penetrates the boundary that ends the zone under the mitigation rule. |
| FVG locked by band | The zone becomes locked by a band, which differs from freezing because it has exceeded its maximum age. |
The New FVG alert uses a closed candle; the other groups monitor the forming candle. Notifications received while a candle is forming should be interpreted alongside that candle's current price state.
The individual alert conditions are enabled in the settings, but the master alert switches for the current symbol and the Scanner are disabled by default. Enable the scope you want to monitor; general configuration instructions are linked in the Scanner and Multi-TF section below.
The Show Buy Signal, Show Sell Signal, Show Bullish Dot, Show Bearish Dot options control the corresponding chart symbols. Show Trend-Aligned FVGs controls zone visibility; hiding the zones does not automatically disable Buy/Sell calculations or related events.
3. Scanner and Multi-TF
Scanner and Multi-TF extend the indicator's monitoring across multiple symbols and timeframes. The interpretation of trends, FVGs, and signals remains specific to the symbol and timeframe being analyzed.
Scanner — Focus on What Deserves Attention
The Scanner monitors selected symbols and timeframes from one panel. Its signal information provides a starting point for choosing charts to inspect, instead of opening every symbol in turn.
When a signal catches your attention, inspect its chart to determine whether it represents a trend change or a Buy/Sell reaction, and check the state of the relevant FVG.
Multi-TF — Put Signals into Context
Multi-TF provides information from another timeframe. You can use one timeframe to read the broader context and another to observe price reactions at a zone, according to your own approach.
Different timeframes can reflect different states. There is no need to assume that every timeframe must produce the same signal at the same time.
You can select a timeframe list, use separate parameters for each timeframe, and configure the symbols monitored by the Scanner. These shared settings are explained in a separate guide so you can apply them consistently across compatible products.
See the Multi-TF and Scanner User Guide for configuration instructions, parameter explanations, and guidance on using the shared features.
4. How to Use the Indicator
The following sequence offers a way to connect the layers of information on the chart. Each step focuses on a specific question.
- Read the Trend Context First
Check whether the Uptrend or Downtrend line is active and whether a new trend-change dot has appeared. This helps distinguish the trend state from a short-term price reaction.
- Identify Eligible FVG Zones
Observe the zone's position relative to price, its bullish/bearish type, and its active state. A box still visible on the chart may already be locked or expired; a historical drawing does not automatically mean the zone can still generate signals.
- Watch How Price Interacts with the Zone
Distinguish the first touch from the exit that generates a Buy/Sell signal. Use the Buy/Sell Volume relationship as additional context, while remembering that signals on the forming candle can still change.
- Use the Scanner to Narrow Your Watchlist
Select notable cases from the Scanner, then examine their charts to understand each signal within its FVG structure and trend context.
- Use Multi-TF for Additional Context
Refer to another timeframe when you want to place the current reaction in a broader context. If two timeframes point in different directions, treat this as information about the two contexts being observed rather than automatically assuming a signal error.
Reading example: when observing an active Bullish FVG, a return to the zone indicates interaction only. If price subsequently exits above the top of the zone and meets the minimum-age requirement, a Buy arrow may appear. You can use the Scanner to find similar cases and Multi-TF to add context, rather than treating the creation of a new FVG as a Buy signal.
The value of Trend Fair Value Gap Delta Multi TF Scanner lies in connecting market direction, price zones, and actual price reactions. Understanding each component helps you select information that fits your approach while maintaining a consistent observation process.
