FVG – (auto close + age) GR V1.0

FVG – Fair Value Gaps (auto close + age counter)

Short Description

Automatically detects Fair Value Gaps (FVGs) on the current timeframe, keeps them open until price fully fills the gap or a maximum bar age is reached, and shows how many candles have passed since each FVG was created.

Full Description

This indicator automatically finds and visualizes Fair Value Gaps (FVGs) using the classic 3-candle ICT logic on any timeframe.

It works on whatever timeframe you apply it to (M1, M5, H1, H4, etc.) and adapts to the current chart.

FVG detection logic

The script uses a 3-candle pattern:

Bullish FVG
Condition:
low[0] > high[2]
Gap zone:

Lower boundary: high[2]

Upper boundary: low[0]

Bearish FVG
Condition:
high[0] < low[2]
Gap zone:

Lower boundary: high[0]

Upper boundary: low[2]

Each detected FVG is drawn as a colored box (green for bullish, red for bearish in this version, but you can adjust colors in the inputs).

Auto-close rules

An FVG remains on the chart until one of the following happens:

Full fill / mitigation

A bullish FVG closes when any candle’s low goes down to or below the lower boundary of the gap.

A bearish FVG closes when any candle’s high goes up to or above the upper boundary of the gap.

Maximum bar age reached

Each FVG has a maximum lifetime measured in candles.

When the number of candles since its creation reaches the configured maximum (default: 200 bars), the FVG is automatically removed even if it has not been fully filled.

This keeps the chart cleaner and prevents very old gaps from cluttering the view.

Age counter (labels inside the boxes)

Inside every FVG box there is a small label that:

Shows how many bars have passed since the FVG was created.

Moves together with the right edge of the box and stays vertically centered in the gap.

This makes it easy to distinguish fresh gaps from older ones and prioritize which zones you want to pay attention to.

Inputs

FVG color – Main fill color for all FVG boxes.

Show bullish FVGs – Turn bullish gaps on/off.

Show bearish FVGs – Turn bearish gaps on/off.

Max bar age – Maximum number of candles an FVG is allowed to stay on the chart before it is removed.

Usage

Works on any symbol and any timeframe.

Can be combined with your own ICT / SMC concepts, order blocks, session ranges, market structure, etc.

You can also choose to only display bullish or only bearish FVGs depending on your directional bias.
