Dynamic EMA

📌 Script Title: Dynamic EMA by Timeframe & Color

🔍 Purpose
This script automatically plots a single Exponential Moving Average (EMA) that adapts based on the current chart timeframe, making it ideal for multi-timeframe traders who want to keep their charts clean and focused. It also changes the color of the EMA to visually reinforce which EMA is active.

⚙️ How It Works
The script checks which timeframe you're currently on and:

Selects the corresponding EMA length

Plots that EMA on your chart

Colors the EMA based on its timeframe to help you quickly identify which one you're using

Here’s the timeframe-to-EMA mapping used:

Timeframe EMA Used EMA Color
3-Day EMA 7 White
Daily EMA 21 Blue
4H EMA 50 Green
1H EMA 100 Orange
15-Min EMA 200 Red
Other EMA 21 Gray (Default)

🧠 Why This Is Useful
Clarity & Focus
Instead of plotting multiple EMAs for all timeframes and cluttering your chart, this script shows only the one most relevant to your current view.

Multi-Timeframe Efficiency
If you're a trader who shifts between long-term and short-term views (like 3D → Daily → 4H → 15m), the EMA automatically adjusts itself — no need to manually reconfigure settings.

Color Coding for Visual Recognition
Each timeframe's EMA has a distinct color, so you can recognize which one is in play without even reading the label.

✅ How to Use Effectively
Switch timeframes in TradingView and observe how the EMA and its color update automatically.

The script works best on:

3D

Daily

4H

1H

15m
Any other timeframe will use EMA 21 with a gray color as a fallback.

Use with Trend Analysis: This EMA can serve as:

A trend filter (price above = bullish, below = bearish)

A dynamic support/resistance guide

Combine with Price Action: Watch how price reacts to the current EMA (e.g., bounces, rejections, crossovers).

Use in Confluence: Combine this with candlestick patterns, volume, or other indicators for higher-confidence entries.
