Harmonic + Ratio — Multi-Pattern Reversal System
A precision reversal indicator that combines classic Harmonic chart patterns (ABCD, Gartley, Bat, Butterfly, Crab)
Most harmonic indicators flood the chart with every geometrically valid pattern. Harmonic + Ratio refuses to fire unless the pattern's shows imbalance in the reversal direction and a qualifying candle structure — turning a noisy pattern scanner into a selective trading tool.
🔹 Core Features
- 5 harmonic patterns detected automatically — ABCD, Gartley, Bat, Butterfly, and Crab. Each can be individually enabled or disabled.
- Four tolerance tiers — from Very Aggressive (15%) for early entries to Very Defensive (4%) for textbook-perfect patterns only.
- Candle confirmation layer — optional filter requiring Piercing Line, Dark Cloud, Bullish/Bearish Engulfing, Inside Bar, or Pin Bar formation.
- Setup-latching logic — one arrow per completed pattern, no repainting once confirmed.
- Automatic SL and two R-multiple TPs (1.5R and 2.5R by default, fully configurable).
- On-chart dashboard with live Fibonacci ratios (AB/XA, BC/AB, CD/BC, AD/XA), pattern name, direction, entry, SL, and targets.
- Popup and push alerts on every confirmed signal.
🔹 How It Works (For Traders)
When a valid harmonic pattern completes, the candle body closes in the right direction, and (optionally) a proven candlestick reversal pattern forms — the indicator prints a BUY or SELL arrow with a full trade plan.
Every pattern's geometry is drawn in real time on the chart, labeled with its type (Gartley, Bat, etc.) and direction (BULL/BEAR). The dashboard tells you exactly why the signal qualified.
🔹 Recommended Use
Swing traders (D1)
- Use the Defensive or Very Defensive tolerance for the cleanest patterns.
- Keep Candle_Confirm enabled — the extra confluence improves win rate significantly.
- Take the full plan: TP1 for partial close, TP2 for the full move.
Intraday traders (M30, H1, H4)
- Switch to Very Aggressive tolerance for more frequent signals.
- Pivot strength to 15–20 for pattern detection.
- Pair with session filter — best results during London and New York sessions.
Pattern specialists
- Disable the patterns you don't trade and enable only your favorites (e.g., Bat + Butterfly only).
🔹 All Configurable Inputs
- Pivot strength, pattern tolerance, individual pattern toggles
- Ratio length and threshold
- Body % requirement and fancy candle confirmation toggle
- ATR period, SL × ATR, TP1 / TP2 reward ratios
- Bull / Bear / guide-line colors and widths
- Dashboard visibility and alert preferences
🔹 Why This Indicator Stands Out
- ✅ Non-repainting — once an arrow prints, it stays.
- ✅ Selective by design — prints rarely, prints well. Quality over quantity.
- ✅ Complete trade plan — entry, stop, and two targets delivered automatically.
- ✅ Works on all symbols — forex, crypto, indices, stocks, commodities. Every timeframe.
- ✅ Visually self-documenting — you see the pattern drawn, you see the ratios in the dashboard, you see the plan.
🔹 Who This Is For
- Swing traders who wait patiently for A+ setups.
- Technical traders who respect harmonic geometry but want modern filtering on top.
- Signal providers needing clean, objective entries with defined risk.
- Anyone tired of indicators that fire on every wiggle.
🔹 Who This Is NOT For
- Traders expecting dozens of signals per day (by design — it's selective).
- Pure trend followers (this is a reversal tool).
- Anyone looking for a "holy grail" — this is a high-conviction filter, not a magic autopilot.
All parameters are exposed and fully adjustable. No hidden subscription, no external dependencies, no background servers — the indicator is self-contained and runs entirely on your MetaTrader terminal.
