🌊 Ride the trend. Skip the noise.
A pro-grade trend filter built on the classic Coral (linear IIR) with cascaded EMAs (order 3-6) and a normalized-slope engine. It paints a crystal-clear Up / Down / Neutral bias and fires real-time crossover arrows with matching on-chart pop-ups (N seconds) and optional sound-strictly one alert per bar.

🎯 Why traders choose it

• Instant bias: color-coded Coral dots - green / red / yellow.
• Trade with discipline: above Coral → long-only, below → short-only.
• Actionable entries: intrabar Buy/Sell arrows on price×Coral cross.
  Signal Mode: By Trend (cleaner) or All Crosses (more setups).
• Stay sharp: on-chart alert + sound (optional), anti-spam 1/bar.
• Readability on point: optional Color Bars tint candles by trend.
• Preset power: Scalp / Swing / Long tuned out of the box.
• Heads-up HUD: compact Dashboard - Trend, NormSlope, Period, Order, Above/Below.
• Algo-ready: public series TrendState (−1/0/+1) and NormSlope for cBots/scanners.
• Lightweight & robust: smooth Coral baseline, optimized for any symbol/timeframe.

⚡ How it works (in practice)

• Coral = 3-6 EMA cascades → silky smoothing with minimal lag.
• Trend engine = slope normalized by ATR or pips; Neutral Threshold controls the flat zone width.
• Arrows & alerts trigger as the bar crosses the Coral (per Signal Mode).
• Pop-up shows for ScreenAlertSec seconds; sound follows the AlertSound toggle.

🎯 Presets & Recommended Timeframes

Coral Filter X Pro includes three ready-to-use presets, each designed for a different trading horizon.

⚡ Scalp | M5-M15
Fast and responsive trend detection for scalping and intraday trading. Recommended starting timeframe: M15.

🌊 Swing | M30-H1
Balanced smoothing for identifying medium-term trends while filtering short-term market noise. Recommended starting timeframe: H1. H4 may also be used for broader trend analysis.

🏔️ Long | H4-D1
Stronger smoothing for identifying longer-term market direction and reducing sensitivity to minor price fluctuations. Recommended starting timeframe: H4.

How to choose your preset

• The indicator uses the timeframe of your current chart.
• Each preset automatically applies its own Period, EMA Order and Neutral Threshold settings.
• For manual adjustments, select the Custom preset.
• Green = Uptrend, Red = Downtrend, Yellow = Neutral.
• Neutral indicates that the normalized trend slope does not exceed the selected threshold.
• A visible trend does not necessarily generate a Buy/Sell arrow. Arrows require separate signal conditions.

These timeframe recommendations are suggested starting points. Signal frequency and responsiveness vary depending on the instrument, volatility and market conditions.

Scalpers, intraday, swing, and algo traders who want a clean, disciplined bias, fast entries, and automation-friendly outputs.
