EMA Percent Angle & Slope Visualizer

EMA Percent Angle & Slope Visualizer is a powerful trend-strength tool that measures the true geometric slope of an EMA using percent-normalized angle calculations.
Unlike raw angle or ATR-based angle methods, this indicator uses the formula:

angle = atan( (EMA_t - EMA_(t-1)) / EMA_(t-1) ) * (180 / pi)


This gives you a universal slope measurement that works across stocks, indices, currencies, and crypto — regardless of price scale.

📌 Why Percent-Normalized Angle?
Raw price angle is meaningless because angles depend on chart scaling.
Percent-normalized angle gives a true slope, equal across all instruments.

✔ Tip
Slopes above +0.15° and below –0.15° represent strong trend phases for Nifty.
