YBL – EMA Pro (Rellena + Borde) + Alertas

YBL – EMA Pro is a clean, high-visibility EMA tool designed to be your main bias line on any timeframe.
It uses a double-layer plot (filled core + sharp border) and includes non-repainting alerts when price crosses and flips the EMA color.

🔧 Core features
• Configurable EMA length
• Single input: EMA Length (default 50).
• Works on any symbol and timeframe.
• Double-layer EMA styling
• Base layer: thick, semi-transparent line to create a smooth “filled” band around the EMA.
• Border layer: thinner, solid line on top for precise reading.
• Both layers change color together:
• Green when price is above the EMA.
• Red when price is below the EMA.

This makes the EMA extremely easy to read even on busy charts or small devices.

🎯 Trend bias & context
• Above EMA (green) → bullish regime / support zone.
• Below EMA (red) → bearish regime / resistance zone.

You can use it as:
• A trend filter (only take longs when EMA is green, shorts when red).
• A dynamic trailing guide for swing or intraday trading.
• A clean visual anchor combined with other YBL tools (volume, order flow, S/R, etc.).

🔔 Alerts (color flip / cross)

The script includes two ready-to-use alert conditions:
• “EMA a VERDE (precio > EMA)”
• Triggers when price crosses from below to above the EMA, or when the logic detects a fresh flip to green.
• “EMA a ROJO (precio < EMA)”
• Triggers when price crosses from above to below the EMA, or when the logic detects a fresh flip to red.

The conditions are built with crossover / crossunder plus confirmation logic to avoid repainting issues and only fire on confirmed color change.

You can attach TradingView alerts to:
• Catch trend shifts early.
• Automate notifications when a symbol enters or exits your preferred regime.
