DTFX Fusion Suite (Supertrend + QQE + FVG)

A7 is a structure-driven trading strategy framework built around liquidity behavior
rather than indicator prediction.

Core sequence:
Sweep → First Return → Pullback → Reversal Trigger

Key concepts:
1. Trades are considered only after a clear liquidity sweep.
2. The system enforces a mandatory First Return, preventing chase entries.
3. Entries require a pullback followed by a reversal trigger
(Engulfing or Impulse candle).
4. Trend and regime filters are applied to avoid structurally adverse conditions.

About the 4H Heikin Ashi FVG:
- The 4H HA Fair Value Gap is used strictly as higher-timeframe visual context.
- It does NOT generate entries.
- It does NOT act as a buy/sell signal.
- Its purpose is environmental awareness and trade management context only.

Included components:
- Liquidity sweep state machine
- First Return time window constraint
- Pullback validation logic
- Engulf / Impulse reversal triggers
- EMA, Supertrend, and LWMA trend filters
- Structure-based stop and trailing exit logic
- 4H HA-FVG visualization (non-signal)
