ICT 9:30am First FVG

2024年8月27日

This indicator is designed based on ICT (Inner Circle Trader)'s algorithmic price action theory, specifically targeting the first fair value gap (FVG) that forms immediately after the New York Stock Exchange opens at 9:30am. The FVG represents an imbalance in the price delivery where a significant price action gap occurs, which can play a crucial role in future price movements.

Features:

• Identification of First FVG: Automatically identifies and plots the first fair value gap that forms post the 9:30am NY open.
  
• Customizable Visualization: Choose between block or line styles for visual representation, with customizable colors and border styles.
  
• Date Labeling: Optionally displays date labels for each identified gap to track patterns over time.
  
• Imbalance Extension: Options to extend the imbalances to the current bar, helping to visualize their influence on ongoing price action.
  

Purpose:

The first fair value gap formed after the market opens is an important algorithmic price range in ICT's price action theory. This indicator simplifies the identification of these critical gaps and helps in understanding their impact on future price action.
