ICT iFVG Detector and Alert [by ote618]

Description
This script detects ICT - fair value gaps (FVG) formed by price gaps between Candle 1 and Candle 3, then monitors the next 5 candles for an inverse fair value gap (iFVG).

What It Detects
Bullish FVG: When Candle 1 high is below Candle 3 low (BISI)
Bearish FVG: When Candle 1 low is above Candle 3 high (SIBI)

Once an FVG is detected, the script checks the next 5 candles:

A Bullish FVG becomes a Bearish IFVG if price closes below Candle 1 high
A Bearish FVG becomes a Bullish IFVG if price closes above Candle 1 low

Only the first bar that validates the FVG triggers the transition to an IFVG.

Visual Output
A shaded rectangle is plotted to mark the original FVG zone (from Candle 1 to Candle 3)

Color-coded:
Red for Bearish IFVG (validated Bullish IG)
Green for Bullish IFVG (validated Bearish IG)

The rectangle extends from Candle 1 to the validating bar

Alerts
You can receive alerts when an FVG becomes an IFVG:

Configurable to fire only on selected timeframes (1m, 5m, 15m, 60m)
Alerts include the direction and the chart timeframe

Settings
Enable Alerts For Timeframe: Choose which timeframe(s) trigger alerts

This tool helps traders identify inverse FVGs (iFVG), a useful ICT concept.

Summary of Changes

1. Multi-Timeframe Alerts (User-Selectable)
The indicator now supports alerts from multiple timeframes at the same time, independent of the chart timeframe.
Available alert timeframes:

1 minute
2 minutes
3 minutes
4 minutes
5 minutes
15 minutes
60 minutes (1 hour)
240 minutes (4 hours)
Daily
Weekly
Monthly

Each timeframe can be enabled or disabled individually using checkboxes in the indicator settings.

2. Alerts Trigger on Confirmed Bar Close
Alerts fire:

Only after the selected timeframe bar has closed
Once per timeframe bar (no repeated alerts)
Even when viewing a different chart timeframe

Example:
If you are viewing a 1-minute chart and a 15-minute iFVG confirms, the alert will trigger when the 15-minute bar closes.

3. Direction-Aware Alert Messages
Each alert message clearly states:

Bullish or Bearish iFVG
The timeframe that generated the alert

Optionally, the current chart timeframe

Example alert message:
Bullish iFVG confirmed on 15m (chart 1m)

4. Visual Customization (Previously Added)
The indicator now includes user-controlled styling options:

Bullish iFVG fill color
Bearish iFVG fill color
Fill transparency
Border color
Border transparency

These settings affect visuals only and do not impact alert logic.

How to Use the New Features
Step 1: Add the Indicator

Add ICT iFVG Detector and Alert [by ote618] to your chart.

Step 2: Select Alert Timeframes

Open the indicator Settings
Go to the Inputs tab
Locate the Alert Timeframes section
Check all timeframes you want to receive alerts from

Example configurations:
Scalping: 1m, 2m, 5m
Day trading: 5m, 15m, 60m
Swing trading: 60m, 240m, Daily
Higher-timeframe bias: Daily, Weekly, Monthly

You may select any combination.

Step 3: Enable Alerts
Ensure the following inputs are set as desired:

Enable Alerts: ON
Include Chart TF in Message: Optional

Step 4: Create the TradingView Alert
This step is required for alerts to work.

Click Create Alert
Set Condition to this indicator
Set Trigger to Any alert() function call
Leave frequency at default
Create the alert

Do not select a specific plot or “once per bar” option. The script controls alert timing internally.

How the Logic Works (Conceptual)

Boxes are always drawn on the current chart timeframe
Alerts are evaluated on the selected alert timeframes
Each timeframe runs independently
Alerts do not repaint and do not repeat
You can monitor multiple higher and lower timeframes from a single chart.

Notes and Limitations

Boxes do not project higher-timeframe zones onto lower-timeframe charts
Alerts are not session-filtered (RTH/ETH) in the current version
One alert can fire per enabled timeframe on the same bar

1. Validation Window

The Validation Window controls how long a Fair Value Gap (FVG) has to invalidate before it becomes a confirmed iFVG.

When an FVG is detected, price must close beyond the FVG boundary within the number of bars you set. If it does, the iFVG is confirmed. If it does not happen within that window, the setup expires and no signal is generated.

Example:
If the Validation Window is set to 5, the setup must confirm within 5 total bars (the detection bar plus the next 4 bars). If price does not invalidate the FVG during that time, it is ignored.

This setting lets you control how quickly a setup must react to remain valid.

2. Multi-Timeframe Alerts

You can enable alerts for multiple timeframes at the same time (1m, 5m, 15m, 1H, Daily, etc.).

To use multi-timeframe alerts:

Open the indicator settings.
In Inputs, check the timeframes you want alerts for.
Create an alert and select “Any alert() function call” as the trigger type.

For best results, set your chart to 1-minute. This ensures lower timeframe alerts (like 1m or 5m) trigger correctly while higher timeframes continue to work normally.

Each selected timeframe will trigger alerts independently based on its own confirmed iFVG signals.
