Sero is a stochastic-based momentum oscillator designed to identify market momentum shifts through clear, color-coded visual signals. It calculates a smoothed stochastic value from the Typical Price [(High + Low + Close) / 3] over a 15-bar range, then applies a fast 2-period exponential moving average (EMA) to generate a responsive oscillator ranging from 0 to 100.
The indicator displays multiple colored lines to represent momentum states:
- Yellow line: base Sero value (always visible)
- Red line: bullish momentum (rising oscillator)
- Thick red line: strong bullish momentum (rising and above 20, indicating breakout from oversold)
- Green line: bearish momentum (falling oscillator)
- Thick green line: strong bearish momentum (falling and below 20, indicating deep oversold conditions)
Key signals include buy signals when the color flips from green to red, especially below 20 (oversold reversal), and sell signals when it flips from red to green, especially above 80 (overbought reversal). Thick lines confirm strong momentum trends, while thick green lines below 20 may indicate exhaustion of selling pressure and potential reversal.
Sero works on any timeframe and instrument without requiring user settings, and it is recommended to combine it with price action or support/resistance levels for confirmation. Color transitions near extremes (0 or 100) provide the highest-probability signals.
