THUẬN-TB

The provided code combines two distinct Pine Script indicators into a single script for TradingView, both based on Smart Money Concepts (SMC).

1. The "THUẬN-TB" Indicator
This part of the code focuses on identifying and visualizing supply and demand zones. It automatically detects and plots swing highs and lows to define these zones, which are areas of potential selling (supply) or buying (demand) pressure. The indicator also tracks break of structures (BOS), which occur when price closes beyond these zones, signaling a continuation of the trend. It can also display a zigzag line and price action labels like HH and LL.

2. The "CauTrucFVG" Indicator
This section is dedicated to tracking market structure, Fair Value Gaps (FVGs), and Fibonacci retracement levels.

FVGs are price imbalances identified by three-candle patterns, and the script draws boxes to highlight these areas, which are expected to be filled by future price movements.

Market structure is defined by BOS (for trend continuation) and Change of Character (CHoCH) (for trend reversal), both of which are automatically labeled on the chart.

Finally, the indicator can draw five customizable Fibonacci levels based on the current market structure, providing potential points of interest for trades.

In essence, the combined script provides a comprehensive toolkit for SMC traders, using the first part to find key liquidity areas (supply/demand) and the second part to analyze the broader market structure and imbalances.
