FIB 21/8 EMA Logic HyperTrend w/ ATR Bands & Buy/Sell Indicators

EMA LOGIC SUPERTREND
────────────────────────────────────────────
EMA Logic SuperTrend is a SuperTrend-style overlay that replaces traditional
price/ATR trend logic with a stateful, debounced EMA momentum engine.

It preserves the classic SuperTrend visuals:
- Trend bands
- Buy/Sell markers
- Background shading

But ALL trend direction is determined strictly by EMA behavior.

CORE TREND LOGIC
────────────────────────────────────────────
• Uses two EMAs (default: 8 & 21)
• GREEN (Buy Trend):
- Both EMAs rising for 2 consecutive candles
• RED (Sell Trend):
- Fast EMA falling for 2 consecutive candles
• Includes a 2-bar debounce filter to reduce whipsaw
• Uses a state machine for clean flips:
- Buy only on RED → GREEN
- Sell only on GREEN → RED

• ATR is NOT used for entries or exits
• ATR ONLY controls how far the bands sit from price
