FVG fill with immediate rebalance [LuciTech]

The "FVG fill with immediate rebalance AKA Golden Arrow" indicator is designed to identify Fair Value Gaps (FVGs) and detect immediate rebalances to highlight potential trading opportunities. It uses colored boxes to mark FVGs and triangular markers to signal bullish or bearish setups, helping traders pinpoint key price levels where imbalances occur and price reactions are likely.

Key Features

FVG Detection: Spots bullish and bearish Fair Value Gaps based on price action, with customizable width settings.
Golden Arrow Signals: Displays triangular markers when price fills an FVG and immediately rebalances, indicating potential reversal or continuation zones.
Customizable Colors: Bullish FVGs appear in green and bearish FVGs in red by default, with options to tweak colors in the settings.
Time Filter: Allows signals to be restricted to a specific time window, highlighted by a background fill for clarity.
Alert System: Supports TradingView alerts for "Bullish Golden Arrow" and "Bearish Golden Arrow" signals to keep traders updated on setups.
How It Works

FVG Calculation: Analyzes gaps between candles to identify FVGs, with user-defined minimum width options (points, percentages, or ATR-based).
Signal Generation: Triggers a Golden Arrow signal when price fills the FVG and rebalances immediately, based on wick penetration and closing conditions.
Visual Aids:
Bullish FVGs are shown as green boxes, bearish FVGs as red boxes.
Upward triangles mark bullish signals, downward triangles mark bearish signals.
Time-Based Filtering: Optionally limits signals to specific hours, with a background fill showing the active period.
