RatioFangClassic Harmonic Pattern Indicator

- Versione: 1.0
- Attivazioni: 5
RatioFangClassic detects five classic harmonic patterns on your chart and draws the PRZ (Potential Reversal Zone) together with entry, stop-loss and take-profit guides. It is a display-only indicator: it never places, modifies or closes orders.
What it detects
Butterfly, Gartley, Bat, Crab and ABCD, both bullish and bearish. Each pattern is checked against its commonly published Fibonacci ratios, with an adjustable tolerance. Every pattern can be turned on or off.
What you see on the chart
- The X-A-B-C-D legs with the ratio of each leg
- The PRZ band and an invalidation line
- Entry, stop-loss and three take-profit guide lines with the risk/reward of each target
- The pattern name (Bullish / Bearish) in the top-right corner
- A compact info panel (top left): pattern, ratio accuracy, PRZ range, price and distance to the PRZ, risk in pips. No lot guide or oscillator display
Alerts
Optional popup, push notification and email alerts when price enters the PRZ.
Languages
Chart labels and alerts are available in English, Japanese, Simplified Chinese, Traditional Chinese and Spanish. The default is Auto (follows the terminal language).

Notes
- Works on any symbol and any timeframe. Patterns are detected from past price data, so the display can change as new bars form.
- Harmonic patterns do not guarantee any result. The entry, stop-loss and take-profit lines are guides based on the pattern geometry, not trading advice or a promise of profit. Test on a demo account first.
- The indicator does not use DLLs or external files.
