Smart Trail + Trend Ribbon

Smart Trail + Trend Ribbon

This script combines a smart trailing system with an EMA-based trend ribbon to help you quickly read trend direction, potential reversals and dynamic support/resistance zones.

1. Smart Trail
The Smart Trail module is based on an external library function getSmartTrail() and plots a dynamic trailing line that adapts to market conditions.

• The line switches its state between long and short depending on price action.
• When the direction is long, the trail is colored with the Up Color; when short, it uses the Down Color.
• The area between the main trail and the filler line is shaded to highlight the active bias and strength of the move.

Smart Trail inputs:
• Trail Period – base length for calculating the trail.
• Param A / Param B – additional sensitivity and smoothing parameters that control how fast the trail reacts to price changes.
• Up Color / Down Color – visual colors for long/short regimes.

Use it as a dynamic support/resistance reference or as a trailing level for managing open positions.

2. Trend Ribbon (EMA Ribbon)
The Trend Ribbon block uses two EMAs calculated on hlc3 (average of high, low and close) and creates a colored band between them.

• When EMA Ribbon 1 is above EMA Ribbon 2, the area between them is filled with Uptrend Colors.
• When EMA Ribbon 1 is below EMA Ribbon 2, the area is filled with Downtrend Colors.
• The ribbon is slightly expanded relative to the EMAs using the current price range to make the zone more visible on the chart.

Trend Ribbon inputs:
• EMA Ribbon 1 Period – faster EMA.
• EMA Ribbon 2 Period – slower EMA.
• Uptrend Color / Uptrend Color (2) – main and secondary colors for bullish conditions.
• Downtrend Color / Downtrend Color (2) – main and secondary colors for bearish conditions.

This gives you a clear visual filter of the current trend and helps avoid trading directly against the dominant direction.

How to use
• Combine the Smart Trail direction with the Trend Ribbon bias to confirm entries and exits.
• Long setups are stronger when the Smart Trail is in long mode and the Trend Ribbon shows an uptrend.
• Short setups are cleaner when the Smart Trail is in short mode and the Trend Ribbon shows a downtrend.
• Works on any symbol and timeframe; parameters can be tuned to your trading style (scalping, intraday, swing).
