SMART FVG

What it does

A "Fair Value Gap" (FVG) is a small gap left behind in price when a move happens so fast that a whole price area gets skipped over — nobody actually traded there. It shows up as a gap between three candles in a row. These gaps often get "filled" later, meaning price comes back to trade through that skipped area before continuing on its way (or reversing). This indicator finds these gaps automatically and draws a box around each one.

It also tells you which gaps look more important: a gap is marked "STRONG" only when BOTH of these are true at the same time — the gap is unusually large (measured against recent average volatility) AND the candle that created it traded on unusually high volume. Both conditions have to be true together; a big gap on quiet volume, or high volume with only a small gap, does not count as Strong. This two-part check is stricter than simply flagging "any big gap," which is what most similar tools do.



How to actually use it (step by step)

Let gaps form naturally as price moves. Each one is drawn as a colored box — green/cyan-ish tones for bullish (demand) gaps, red/orange tones for bearish (supply) gaps.
Pay extra attention to boxes marked "STRONG" — these represent a real, forceful, high-conviction move, not just random noise.
When price comes back down (or up) into a gap box, that's a potential trade opportunity — buy near a bullish gap, sell near a bearish gap — especially reacting at the dotted 50% line drawn through the middle of the box.
Look at the small number in the corner of each box — it counts how many candles ago the gap formed. A small number (fresh gap) is generally considered more reliable than a large number (old, already-tested-many-times gap).
If you turn on the higher-timeframe overlay, you'll also see gaps from a bigger timeframe (marked "HTF") plotted directly on your current chart — these represent bigger, more significant levels than same-timeframe gaps.
Every setting explained



Visualization group

Bullish FVG / Bearish FVG — the fill color for ordinary gaps.
Strong Bullish FVG / Strong Bearish FVG — the fill color for gaps that pass the "Strong" test above.
Show 50% Line (EQ) — draws a line through the exact middle of every gap box; this is a common spot for price to react to.
EQ Line Color.
Width Mode — controls how far the box stretches to the right: "Dynamic" keeps growing the box to reach today's candle in real time, "Fixed" stops the box at a set number of candles wide, "Extended" stretches the box all the way to the right edge of your screen forever.
Fixed Width (bars) — how many candles wide the box is, only used when Width Mode is set to Fixed.
Min FVG Size (x ATR) — the smallest gap size the script will bother drawing, measured against recent average volatility. Raise this to ignore tiny, insignificant gaps; set to 0 to see every gap no matter how small.
Mitigation group (mitigation = "price has now traded back through the gap")

Delete Mitigated Zones — when turned on, a gap box disappears completely once price fills it. When off, it stops growing and stays on the chart as a faded historical marker.
Mitigation Level — decide what counts as "filled": either price reaching the halfway (50%) point of the gap, or price completely closing the entire gap.
Mitigation Confirmation — decide what counts as reaching that level: any wick poking into it ("Wicks"), or a full candle close past it ("Close" — stricter, fewer false triggers).
Imbalance Age group

Show Age Label — displays a small number (like "34b") showing how many candles ago the gap was created.
Fade Old Zones — when turned on, gap boxes slowly become more transparent as they age, so your eye is naturally drawn to the freshest ones.
Max Age for Full Fade (bars) — how many candles it takes for a gap to reach maximum fade/transparency.
Strong Imbalance group

Mark Strong Imbalances — master on/off switch for the whole Strong-gap detection described above.
Min Gap Size (x ATR) — how big the gap must be (relative to recent volatility) to count toward "Strong" — this is one of the two required conditions.
Min Volume (x SMA 20) — how much higher than the recent 20-candle average volume the gap-forming candle's volume must be — this is the second required condition. Both this and the size condition must be true at the same time.
Show 'STRONG' Tag — shows the word "STRONG" written inside qualifying gap boxes.
Labels group

Show Labels — master switch for all text written inside gap boxes (age number, STRONG tag, HTF tag). Turn this off to hide all text and keep only the colored boxes.
Label Text Color.
MTF FVG group (MTF = "multiple timeframes")

Show Higher Timeframe FVGs — turns on the overlay of gaps from a bigger timeframe, drawn directly on your current chart.
Higher Timeframe — which bigger timeframe to pull gaps from (should be higher than whatever timeframe you're currently viewing).
HTF Bullish FVG / HTF Bearish FVG — colors for these imported higher-timeframe gaps.
Show HTF Label — shows an "HTF" tag inside these imported gaps so you can tell them apart from same-timeframe ones.
