Sero — Momentum Oscillator

Sero is a stochastic-based momentum oscillator that gives clear, color-coded visual signals for market momentum shifts.

How It Works

Sero calculates a smoothed stochastic value from the Typical Price (High+Low+Close)/3 over a 15-bar range, then applies a fast 2-period EMA to produce a responsive 0–100 oscillator.

What to Look For

Colors tell the story:

• Yellow line — the base Sero value (always visible)
• Red line — bullish momentum (Sero is rising)
• Thick Red line — strong bullish momentum (rising + above 20 — confirming breakout from oversold)
• Green line — bearish momentum (Sero is falling)
• Thick Green line — strong bearish dump (falling + below 20 — deep in oversold territory)

Key signals:

1. Buy signal — Color flips from Green to Red, especially from below 20 (oversold reversal)
2. Sell signal — Color flips from Red to Green, especially from above 80 (overbought reversal)
3. Strong trend — Thick lines confirm momentum conviction
4. Exhaustion — Thick Green below 20 = sellers may be running out of steam, watch for reversal

Best Practices

• Works on any timeframe and any instrument
• Combine with price action or support/resistance levels for confirmation
• Color transitions near extremes (0 or 100) are the highest-probability signals
• No settings needed — optimized and ready to use out of the box
