QQE Trend Strategy [Long/Short]

QQE Trend Strategy [Long/Short]

A dual-band QQE (Quantitative Qualitative Estimation) strategy built on Pine Script v6.
Two independently tuned QQE bands — Fast and Slow — provide both responsive and filtered trend signals, with an optional 50-line direction filter and percentage-based stop loss.

━━━━━━━━━━━━━━━━━━━━━━━
🔹 HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━━━
QQE transforms RSI into a smoothed oscillator, then applies a double-EMA ATR trailing band to detect trend reversals.

When the QQE line crosses its trailing band:
- Bullish crossover → Buy signal
- Bearish crossover → Sell signal

Two band systems run in parallel:
- Fast Band (lower factor) — more responsive, earlier signals
- Slow Band (higher factor) — smoother, fewer false signals

Select which band drives your entries via the Signal Band setting.

🔹 FEATURES
━━━━━━━━━━━━━━━━━━━━━━━
- Dual QQE Bands (Fast + Slow)
→ Both plotted simultaneously for confluence analysis.

- 50-Line Direction Filter (optional)
→ When ON: Long entries only above 50, Short entries only below 50.
→ Helps eliminate counter-trend trades in strong trending conditions.

- Trade Direction control
→ Both / Long Only / Short Only

- Stop Loss (optional, percentage-based)
→ Calculated from average entry price.
→ Updated on every bar while in position.

- Display toggles
→ Fast Band, Slow Band, Histogram, Background Color, Bar Color, Signal Markers
→ All independently switchable — use as a standalone indicator or a full strategy.

- Commission & Slippage
→ Defaults: 0.03% commission, 1 tick slippage.
→ Adjustable via Strategy Properties tab without editing the script.
