🐠 Coral Filter X Pro is a professional trend filter based on the classic Coral (linear IIR) algorithm. Built from cascaded EMAs (order 3–6) with a normalized-slope engine, it delivers a clean Up / Down / Neutral view and precise crossover entries.

✅ Main features

• Instant trend clarity: color-coded Coral baseline — Up (green) / Down (red) / Neutral (yellow).
• Trade with bias: above Coral → long-only, below Coral → short-only — simple, robust discipline.
• Actionable entries: Buy/Sell arrows on price–Coral cross (By Trend for cleaner signals, All Crosses for more opportunities).
• Rapid confirmation: optional Color Bars tint candles by trend state.
• All on chart: compact Dashboard with symbol/TF, Period, Order, NormSlope, and Above/Below status.
• Ready on day one: presets for Scalp / Swing / Long-term — tweak and save your own.
• Algo-friendly: exposed series TrendState (−1/0/+1) and NormSlope for cBots and scanners.
• Trustworthy & efficient: non-repainting, lightweight, optimized for multi-charts and any timeframe/symbol.

🧠 Why it works

• True Coral algorithm: linear IIR from EMAs (3–6 cascades) → silky smoothing with minimal lag.
• Normalized-slope trend engine: classifies Up / Down / Neutral using slope normalized by ATR or pips; Neutral Threshold is adjustable (set to 0 to remove the flat zone).
• Clean visual baseline: Coral is plotted as discrete dots along price — clear and unobtrusive.
• Focused execution: optional sound/on-screen alerts on new entries keep you responsive.

⚙️ How it works

• The Coral line is computed via 3–6 EMA cascades for smooth filtering.
• The slope is normalized (ATR or pips) to measure trend strength consistently.
• Color logic: Green = Uptrend, Red = Downtrend, Yellow = Neutral.
• Arrows appear on closes that cross the Coral line (mode-dependent).
• The Dashboard shows live trend, NormSlope, and key parameters.

🎯 How to use in trading

• Trend filter:
• • Price above Coral → consider Buy only.
  • Price below Coral → consider Sell only.
  • Neutral → best to stand aside.
• Entry signals:
• • ▲ Buy — price closes above Coral.
  • ▼ Sell — price closes below Coral.
• Combinations: works great with RSI/Stochastic or candlestick patterns; plug TrendState/NormSlope into cBots for rules.

🔧 Settings guide

Core

• Preset: Scalp (Period 14, Order 3, Threshold 0.05) / Swing (Period 34, Order 5, Threshold 0.10) / Long-term (Period 100, Order 6, Threshold 0.15) / Custom.
• Period: EMA period per cascade (higher = smoother).
• Order (3–6): number of cascades (higher = smoother).
• Neutral Threshold: slope sensitivity; 0 removes Neutral.

Signals & alerts

• Arrow Signals: By Trend (Classic) or All Crosses (Simple).
• Alerts: sound and on-screen notifications on new arrows.

Visuals

• Color Bars: paint candles in trend color.
• Dashboard: show trend, NormSlope and parameters on chart.

For algotrading

• Public series: TrendState (−1/0/+1), NormSlope.

👥 Who it’s for

• Scalpers — quick filtering and fast signals.
• Intraday traders — clear trend structure and entries.
• Swing traders — trend following and reversals.
• Beginners — simple, color-coded guidance.
• Algo traders — direct access to series for automation.

🐠 Coral Filter X Pro turns trend detection into a simple, repeatable workflow — a reliable baseline, clear bias, and disciplined entries in one indicator.
