Inversion FVG Tracker TradingView Indicator

Written by Dominic Walsh · Published 22 Jul 2026

A gap that fails often matters more than a gap that holds. Also, inversion FVG Tracker is a fair value gap indicator TradingView traders can use to follow that failure. It finds three-candle gaps, waits for price to close fully through one, then flips its role. Indeed, a filled bullish gap becomes a resistance zone. A filled bearish gap becomes support. Still, signals key off the flip, not the original gap.

It is free and open source. Thus, you can add it to any chart from the Inversion FVG Tracker script page on TradingView, and the full Pine source is published there for you to read.

What Inversion FVG Tracker plots on the price chart

The script draws two boxes at most: one for the newest bullish gap and one for the newest bearish gap. Hence, each box spans the gap edges, starts two bars back and extends 18 bars to the right. Green marks bullish, pink marks bearish. Next, triangles tagged IFT print below or above signal bars, backed by two larger translucent copies. Signal bars get recoloured and the background carries a faint tint while an inversion bias holds. Then, the dashboard lists state, both gap ranges, total gaps formed, ATR, position and bars since the last signal.

How Inversion FVG Tracker is built

Detecting and ageing a gap

A bullish gap needs the current low to sit above the high from two bars back. Yet, a bearish gap needs the current high to sit below the low from two bars back. The middle candle leaves that space untraded. Truly, the script measures the space and requires at least 0.10 times ATR over 14 bars, which filters out micro-gaps on quiet charts.

Only two gaps live at any time: the newest bullish one and the newest bearish one. Plainly, a fresh gap overwrites the previous one of the same type. Each carries a state number – 1 for open, 2 for inverted, 3 for retested – plus its own age counter.

Unfilled gaps do not last forever. Also, once an open gap passes 60 bars, its state resets to zero and the script stops tracking it. Filled gaps skip that rule, because they have already moved to state 2.

Inversion, bias and entry

Mitigation is strict by default. Indeed, with Mitigate on Close enabled, a bullish gap inverts only when a close prints below the gap’s lower edge. A bearish gap inverts when a close prints above its upper edge. Still, switch the input off and a wick is enough, since the test then uses low and high instead of close.

The moment a gap inverts, the script arms a persistent bias. Thus, a bearish gap that inverts becomes support, so the bias turns bullish. A bullish gap that inverts becomes resistance, so the bias turns bearish. Hence, that bias stays in force until the opposite inversion fires.

Two entry modes exist, and the default may surprise you. Retest-Only Mode ships off. So by default a signal fires on a 9-bar EMA cross in the direction of the armed bias, anywhere on the chart, not at the gap. Next, turn Retest-Only Mode on and signals fire strictly when price returns into the inverted zone, within a 0.10 ATR buffer. That mode produces far fewer marks.

How to read the signals

The State row tells you which regime you are in. Then, BULL FVG INVERTED means the last bullish gap failed, so the script leans bearish. BEAR FVG INVERTED means the opposite. Yet, FVG OPEN means a gap exists but nothing has flipped yet, and under default settings no signal can fire in that state.

The boxes show where the gaps sit, but only the two newest. Truly, the Gaps Formed counter keeps rising as older ones scroll away, so a high count on an empty-looking chart just means earlier boxes have been replaced.

In default mode the entry is an EMA cross, so the triangle can land well away from the drawn zone. Plainly, if you want the classic behaviour where price must come back and test the inverted gap, switch Retest-Only Mode on and expect far fewer signals.

Every Inversion FVG Tracker setting explained

The script exposes 16 inputs, grouped in the settings panel exactly as shown below. Defaults are the published values.

FVG

Setting	What it does	Default	Range
Min Gap x ATR	Gap must span at least k x ATR to register.	0.10	0.0 to 3.0
ATR Length	Sets the atr length used in the calculation.	14	5 to 50
Mitigate on Close	On = FVG inverts when CLOSE passes fully through it.	on	on / off
Retest Buffer x ATR	Sets the retest buffer x atr used in the calculation.	0.10	0.0 to 2.0
FVG Max Age (bars)	Unmitigated FVGs older than this are discarded.	60	5 to 200

Signal Logic

Setting	What it does	Default	Range
Entry Reclaim EMA	After an FVG inverts, a close-cross of this EMA in the inverted-bias direction times the entry.	9	2 to 50
Retest-Only Mode	On = fire strictly on the inverted-FVG retest (rarer, classic). Off = EMA reclaim inside the active inversion bias (more signals).	off	on / off
Cooldown Bars	Sets the cooldown bars used in the calculation.	5	1 to 40

Filters

Setting	What it does	Default	Range

Alerts built into Inversion FVG Tracker

The script ships 14 alert conditions. Also, open the alert dialog on the chart, pick the indicator as the condition source, then choose the event you want. Alerts fire on the close of the bar, so they follow the same confirmed-bar rule the on-chart signals use.

Other markets and timeframes

The gap test is pure price structure and the size filter uses ATR, so the script rescales itself on any symbol. Indeed, gold, indices, crypto and equities need no change to the 0.10 ATR minimum gap or the 0.10 ATR retest buffer. Volume plays no part anywhere in the code. Still, the inputs worth reviewing per market are the 60-bar expiry and the 5-bar cooldown, since gap frequency rises sharply on fast intraday charts.

Limitations worth knowing

The script tracks one bullish and one bearish gap at a time. Thus, it is not a full FVG mapper. If three bullish gaps form in a run, only the newest survives, and the older two vanish from both the boxes and the state machine.

Under default settings the entry has no positional link to the gap. Hence, the inversion arms a bias, then a 9-bar EMA cross times the entry. Traders who expect a strict retest entry must enable Retest-Only Mode themselves.

No stop, target or sizing logic exists here. Next, the tool also holds no higher-timeframe view, since it contains no request.security call and reads only the chart timeframe you have open.

Frequently asked questions

Does the Inversion FVG Tracker repaint?

No. Truly, both signal plotshape calls read buySignal and sellSignal, and each requires barstate.isconfirmed. A gap itself only becomes known once the third candle closes, which follows from the three-candle definition rather than from any repaint.

What counts as an inverted fair value gap?

A gap that price has closed fully through. Plainly, the script then flips its role. A bullish gap that price closed below becomes a resistance zone. Also, a bearish gap that price closed above becomes a support zone.

Why did no signal fire at the retest?

Check Retest-Only Mode. Indeed, with it off, which is the default, a retest only marks the gap as tested and moves its state to 3. The actual entry then waits for a 9-bar EMA cross in the direction of the armed bias.

How small a gap gets ignored?

Anything under 0.10 times the 14-bar ATR. On a symbol with an ATR of 20 pips, that means gaps under 2 pips never register. Raise the input toward 0.30 or 0.50 if your chart produces too many small gaps.

How much should I rely on this indicator?

Treat it as one input, not a decision. Still, it is a chart analysis tool, not trading advice. Test it on your own markets and timeframes before relying on it. Results are not guaranteed; past performance is not indicative of future results.
