Daily EMA21 — Step Line

Indicator: Daily EMA-21 Step Line
A lightweight tool that brings the Daily EMA-21 onto any timeframe chart as a clean, flat “step” line. It helps you see where price is in relation to a key higher-timeframe moving average, without cluttering your chart.

What It Does

• Daily EMA Overlay: Fetches the Daily EMA-21 value and plots it on your chart, no matter what timeframe you’re viewing.
  
• Step-Style Line: Drawn as a horizontal “step” line that only updates once per daily bar, keeping levels crisp and stable.
  
• Repaint Control: Option to use the prior day’s EMA (stable, no intraday repaint) or today’s live-updating EMA.
  
• Alerts: Optional alerts when price crosses above or below the Daily EMA-21.
  

How It Works

• Daily Data Pull: Uses request.security to pull the Daily EMA-21 into any chart.
  
• Flat Within Day: The value stays constant intraday and only “steps” at the next daily open.
  
• Toggle Live/Prior: Choose between a repaint-free prior day close or an intraday-updating live EMA.
  

Configuration Settings

• EMA Length: Default 21 (can be adjusted).
  
• Live vs Prior: Toggle between today’s live EMA or yesterday’s confirmed EMA.
  
• Line Color & Width: Fully customizable.
  
• Alerts: Cross-up and cross-down alerts can be enabled via TradingView’s alert system.
  

Notes

• Built in Pine v5 for reliability and compatibility.
  
• Minimal by design — no tables, no clutter, just a higher-timeframe reference line.
  
• Ideal for swing traders who want the Daily EMA-21 visible on intraday charts (e.g., 65m or 195m).
  
• Not trade advice: this is a context tool to support your own strategy and risk management.
