Vùng đỉnh đáy chính + Bob Volman (Dữ liệu H1)

This indicator combines two powerful components into one tool designed for traders who rely on multi-timeframe structure and price action:

🔹 1. H1 Break-Based Swing Zone Detection
Identifies key swing highs and lows based on H1 "break candle" logic — where a candle closes beyond the wick of the previous candle.

When a previous high or low is broken, a new range is drawn and trend context is updated:

🟢 Uptrend = price breaks above key high → green range

🔴 Downtrend = price breaks below key low → red range

⚪ Neutral = no new break → white range

Key swing points are marked with minimal dot labels on the chart for quick structure recognition.

🔹 2. Bob Volman-Style EMAs & Engulfing Signals (from H1)
Applies EMA 15, 21, and 35 from the H1 timeframe to reflect market bias and volatility.

Highlights the area between EMA 15 and EMA 35 with a colored fill to visualize momentum:

Green = bullish bias

Red = bearish bias

Detects classic Bullish and Bearish Engulfing Candles on H1 and marks them with arrows:

🔽 Red arrow = bearish engulfing

🔼 Green arrow = bullish engulfing
