UM OBV with Signal (EMA/SMA/WMA/NWE)
SUMMARY
A visual OBV trend tool that highlights bullish and bearish volume pressure using smart smoothing and intuitive color-coding.
⸻
WHY THIS INDICATOR?
There are only three variables you can adjust on a chart: price, volume, and time. I wanted a good volume indicator.
⸻
DESCRIPTION
This tool extends classic On-Balance Volume with selectable trend smoothing (EMA, SMA, WMA, or NWE) and visual directional coloring on both OBV and the Signal line. Green shows bullish volume flow, red shows bearish volume flow. Optional crossover markers help confirm shifts in buying pressure.
Nadaraya-Watson Regression (NWE) provides a smooth, non-MA alternative for filtering volume trend noise, and optional dual-NWE coloring helps reduce false flips in choppy markets.
⸻
THE CHART
The indicator is added twice at the bottom; once with a 21 EMA and again with a 55 SMA. The chart has text and illustrations to show where the OBV flipped colors. More red equals more selling pressure. More green equals more buying volume or pressure.
⸻
DEFAULTS
• OBV smoothing length = 3
• Signal = 21 EMA
• Crossover bubbles are hidden/off by default
⸻
SUGGESTED USES
• Combine with price structure, momentum, or volatility tools to confirm trend strength.
• Try switching between EMA and NWE on faster intraday charts to see volume trend earlier.
• Use crossover signals as secondary confirmation rather than standalone entries.
• Use this indicator with your other favorite indicators for confirmation.
• Select timeframes suitable to your style of trading.
• I use the 30-minute, 6-hour, and Daily timeframes.
• I question myself if I am buying something with this indicator being red.
• Experiment with various timeframes and settings.
⸻
AUTHOR OBSERVATIONS
OBV often turns before price—especially when volume surges ahead of breakout levels.
NWE tends to smooth choppy OBV much better than traditional moving averages in noisy markets.
Look for Signal color flips at key support/resistance or volatility inflection points.
