This script plots up to six EMAs calculated from a higher timeframe of your choice (e.g., 1H, Daily) and samples them at a user-defined update interval (e.g., every 5 or 15 minutes). The result is a precise, non-repainting display of higher-timeframe EMAs — visible on any chart, including lower timeframes.

🔧 Features
✅ Choose the source timeframe for EMA calculations (e.g., 1H, Daily)
✅ Set a custom update interval (sampling timeframe)
✅ Plot up to 6 EMAs, each with:

• Individual length
  
• Color customization
  
• On/off visibility toggle
  

✅ Fully overlays on current chart timeframe
✅ Updates on bar close of your chosen sampling interval (no repainting)

🧠 Use Cases
See key EMAs from higher timeframes without switching charts
Lock in values only once per sampling interval (e.g., only update 1H EMAs every 15min)
Avoid noisy intra-bar flicker or repainting
Combine with price action or support/resistance for confluence setups

⚙️ Example Settings
EMA Calculation Timeframe: 1H
Update/Sampling Timeframe: 15m
Chart Timeframe: Any (1m, 5m, 1H, etc.)

🚫 No Repainting
This script uses lookahead=barmerge.lookahead_on to ensure EMAs are stable and only update at the end of each sampling bar.

💡 Tip
Use the shorter sampling_tf (like 5 or 15) to keep your EMA lines responsive but reliable — or set it equal to the calculation TF to see them step only once per bar.
