Best FVG Indicators on TradingView (2026), Code-Read.

Short answer: the popular open-source FVG scripts agree on the gap and disagree on when it's spent. All 15 we read measure wick to wick, candle 1's high against candle 3's low, and none uses bodies. The most boosted open-source one, Super OrderBlock / FVG / BoS Tools by makuchaku & eFe, stops a gap at its first touch; Fair Value Gap by LuxAlgo keeps it until a candle closes through. Both draw on the live candle. For a gap drawn only once candle 3 has closed, kept until a close through, with an alert on each new one, Fair Value Gaps (Volumetric) by Flux Charts is the closest in our read, though by default it skips gaps whose three candles aren't all one colour.

Most lists name FVG indicators.

This one reads them.

What we checked

A fair value gap is the space three candles leave. Bullish: candle 3's low stays above candle 1's high, and the gap runs from that high to that low. Bearish: candle 3's high stays below candle 1's low. Its halfway line is called consequent encroachment, or CE. The gap exists only once candle 3 has closed; until then, candle 3 can still trade back into it. Some scripts call the same thing an imbalance.

An inverse fair value gap (IFVG) is what comes after: a gap a later candle closed through, kept on the chart with its direction flipped (explained, with the full rule). The FVG is the gap while price leaves it alone or fills it; the IFVG starts at the close that ends it.

The rule, on a simulated market. The third tab shows bodies apart and wicks overlapping, which no script here counts:

We searched TradingView's scripts for four terms on 31 October 2026 ("fair value gap", "fvg", "fvg indicator" and "imbalance"), which returned 153 scripts with "fair value", "FVG" or "imbalance" in the name: 121 open source, 26 protected and 6 invite-only. We took the 15 most-boosted open-source scripts that draw three-candle gaps, other than LuxAlgo's IFVG script, which our IFVG roundup reads, and read every line that decides when a gap is drawn and when it ends, including the two TradingFinder libraries that three of them import. The questions:

• The rule: candle 1's wick against candle 3's wick, or bodies? And what else must candle 2 do?
• Size filter: is there a minimum size, in ATR, percent or points?
• When a gap is spent: a touch, its 50% line (CE), a wick to the far edge (a full fill), or a close through?
• Inversion: does a close through flip it into an IFVG?
• When it decides: a gap only exists once candle 3 closes. Does the script draw it on the live candle?
• Alerts, and the licence.

The first question has one answer for all of them: every script here measures wick to wick, and none uses bodies. The third splits them every way it can.

The table

Boosts as TradingView's search showed them on 31 October 2026. ATR(n) is the average true range of the last n candles. Candle 1 is the first of the three, candle 3 the one that completes the gap; the far edge is candle 1's high in a bullish gap, candle 1's low in a bearish one.

LuxAlgo's five, BigBeluga's and Zeiierman's are shared under CC BY-NC-SA 4.0, which doesn't allow commercial use; the other eight under the Mozilla Public License 2.0.

Four of the most boosted have closed code, so they aren't in the table: FVG by Nephew_Sam_ (37,418 boosts), the most boosted of all, Nephew_Sam_'s Market Structure BOS/CHOCH/MSB/FVG/OB/BB (30,639), majky's ICT SM Trades (20,302) and Fair Value Gap by Anche (7,337) are protected, free to add with the code hidden. Two open-source scripts above 7,089 boosts aren't in it either: LuxAlgo's Inversion Fair Value Gaps (15,503), which we read in our IFVG roundup, and Zeiierman's Volume Gaps & Imbalances (8,431), which marks price rows with no traded volume, not three-candle gaps.

Where they part is what price does when it comes back. Three cases on one simulated market: a partial fill, a full fill by a wick, and a close through. makuchaku's, and TradingFinder's Smart Money Concept and ICT Concept, end a gap at the first of these, ChartPrime's and spacemanbtc's at the second, and LuxAlgo's Fair Value Gap and Flux Charts' only at the third.

What the code says

Every one measures wick to wick. All 15 compare candle 3's low with candle 1's high (low > high[2]), or candle 3's high with candle 1's low for a bearish gap. What they add is about candle 2: LuxAlgo's five and Flux Charts' want it to close beyond candle 1, ChartPrime's and BigBeluga's want its high beyond candle 1's, spacemanbtc's wants it to close the gap's way, and TradingFinder's want it at least 1.5 × ATR(55) tall.

makuchaku's is the most boosted open-source one, and a gap lasts until its first touch. Each gap is boxed on the candle that completes it, live, with no size filter. The box stops growing at the first candle whose range crosses one of its edges and stays where it stopped, unless you switch on a grey colour for mitigated gaps. A gap whose middle candle closes through the last swing high, found with a one-candle pivot, is coloured blue as "structure breaking". It has no alerts, and it is shared under MPL 2.0.

LuxAlgo's keeps a gap until a close through it. Its Fair Value Gap boxes each gap for 20 candles to the right and deletes it when a candle closes beyond the far edge. That check runs on the live bar, so a box can vanish mid-candle and come back if price does. Its threshold starts at 0%, so every gap counts, and its four alerts cover new gaps and mitigations. FVG Sessions uses the same rule for the first gap of each day, fades it on a close through, and has eight alerts, including price inside the gap and a cross of its midpoint. Imbalance Detector draws each gap three candles wide with its midpoint and doesn't follow it; only its dashboard, off by default, counts a gap as filled, once a wick passes the far edge. Liquidity Voids splits gaps over 0.5 × ATR(144) into 13 slices and greys each one as price trades into it. FVG Instantaneous Mitigation Signals shows only the gaps the very next candle closes back through, as a signal the other way. All five decide on the live bar and are shared under CC BY-NC-SA 4.0.

TradingFinder's three filter hard and follow one gap each way. All three find their gaps with TradingFinder's FVG Detector library. Smart Money Concept's default filter, "Very Defensive", keeps a bullish gap only if candle 2 is at least 1.5 × ATR(55) tall with a body over 70% of it, candles 1 and 2 close up, candles 1 and 3 have bodies over 35% of their range, and candle 3's high clears candle 2's; ICT Concept's "Defensive" asks less. Only the latest bullish and the latest bearish gap are followed, and their lines stop at the first wick to the near edge. Both scripts' alerts are for order blocks. FVG & IFVG ICT draws through TradingFinder's Order Block Drawing library instead: a gap ends at a wick past its 50% line by default, or after 500 candles, and becomes an IFVG if one of the 8 candles after that wick closes beyond its far edge. A close beyond it on the wick's own candle doesn't count: the library line that ends an IFVG when its gap ends cancels it on that candle. Its alerts fire when a gap or an IFVG ends, not on a new gap. All three decide on the live bar and are shared under MPL 2.0.

Three end a gap on a wick, not a close. LudoGH68's SMC Structures and FVG greys a gap at the first wick into it, sends "FVG has been mitigated", and deletes it once a wick reaches the far edge. It finds gaps on closed candles, reading candles 1 and 3 one candle back, so a gap appears as the next candle opens; the fills it marks on the live one. ChartPrime's FVG Volume Profile deletes a gap on a wick beyond its far edge, and draws a volume profile of candle 2, from lower-timeframe candles, inside it. spacemanbtc's Fair Value Gap shrinks the box as wicks eat into it and deletes it when a wick reaches the far edge, or its midpoint with "MidPoint Fill" on. All three are shared under MPL 2.0.

Two decide on the closed candle. BigBeluga's FVG Order Blocks finds gaps on closed candles, over 0.5% of price by default, but doesn't follow them: each gap is a fixed box ending 5 candles after candle 3, and what stays on the chart is an "order block" one ATR(200) tall behind it, removed once a whole candle passes beyond it. Flux Charts' Fair Value Gaps (Volumetric) comes closest to the textbook life of a gap: found on closed candles, kept until a candle closes beyond the far edge ("Zone Invalidation: Close", its default) or until 200 candles pass with no wick back into it, and alerted as "New FVG" as the next candle opens. Its defaults also skip gaps whose three candles aren't all one colour or that are smaller than ATR(10) ÷ 6, and merge overlapping gaps into one. BigBeluga's is shared under CC BY-NC-SA 4.0, Flux Charts' under MPL 2.0.

Zeiierman's ends a gap at its midpoint, and reads ahead on a higher timeframe. Multitimeframe Fair Value Gap deletes a gap once a wick reaches its 50% line ("Mitigated on mid", on by default), and keeps a gap only if candle 3's body is at least the average body. On the chart's own timeframe it decides on the live bar. Pick a higher one and it reads that timeframe with lookahead on and no offset, so on history a gap shows from the first chart candle of the higher-timeframe candle that completes it, before that candle has closed. It is shared under CC BY-NC-SA 4.0.

Ours

IFVG Desk isn't on TradingView's search: its full Pine v6 source comes in Pine Pro Library, $49 once. It measures wick to wick, keeps gaps at least 0.05 × ATR(14) wide, and decides everything on closed candles; "New gap" is one of its 7 alert conditions. A fresh gap isn't ended by a touch, its 50% line or a full fill: a later candle's close strictly beyond the far edge flips it into an IFVG, which ends on a close strictly beyond its other edge, and any gap expires after 180 candles. It draws the gaps within 8 ATR of price, with a dotted midline. It runs on intraday charts only, and its entries are built around the flip, inside a New York session (09:30 to 11:00 by default), not around the gap itself.

The SMC AI-Scored Toolkit, $39 one-time with its full Pine source, does another job. It boxes order blocks and gaps a quarter of an ATR or wider on bar close, and scores each zone 0–100 on five factors (displacement, volume, a liquidity sweep, higher-timeframe alignment and time of day), frozen when the zone forms. A tested zone counts as held once price moves 1 ATR its way and as failed on a close through it; its 5 alert types, on bar close, include price entering a zone. Its page lists no IFVG flip; IFVG Desk does that. The score describes a zone; it isn't odds. On 1,693 resolved gold-futures zones, the top third by score was respected 2.6 points more often than the bottom third, and shuffling the scores at random gave gaps that size too (p = 0.21; the study).

SMC Basics, also in the library, is the plain version, and its rule is the one the two films above run: gaps of 0.3 × ATR(14) or wider on closed candles, faded at the first touch, removed on a close beyond the far edge, with a CE midline and no alerts.

An FVG and an IFVG are one zone at two moments, so a script that deletes a gap on a close through deletes it at the close an IFVG starts from.

We haven't tested fair value gaps on their own as a trading rule.

Check one yourself

• The rule: find the line with high[2]. low > high[2] measures wick to wick; a script that compares math.min(open, close) with math.max(open[2], close[2]) measures bodies.
• The end: find the line that deletes, greys or stops the box. A close beyond the far edge ends it on a close through; low <= the near edge on a touch; low < the far edge on a wick; (top + bottom) / 2 on its 50% line.
• The close: look for barstate.isconfirmed around the gap, or for candles read one back (high[3] < low[1], as LudoGH68's does). Without either, a box you see live may not be there when candle 3 closes. On a higher timeframe, lookahead = barmerge.lookahead_on with no [1] reads that candle before it closes.

How often does a close end a gap? In the IFVG Playbook's year of 5-minute gold, by IFVG Desk's rule, 86% of gaps flipped into IFVGs, a median 7 candles after forming. The guide has that study, the exact rule and two Pine templates:
