Velocity Cross AI

This indicator is basically a zero-line momentum oscillator with built-in buy/sell crossover signals, designed to behave like a smoothed “pressure gauge” for price direction.

📊 What the indicator does

It works in two layers:

1. 📈 Main Oscillator (Subwindow line)

The yellow line (buffer 0) is a custom Fisher-style normalized momentum value.

It is built from:

• Highest close over a period
• Lowest close over a period
• Mid price (Open + Close)/2
• Recursive smoothing (previous values influence current value)

👉 What it tells you

• Above 0 → bullish pressure
• Below 0 → bearish pressure
• Crosses of zero → potential trend shifts

So it behaves like:

• RSI-like momentum
• Fisher Transform-like turning signal
• Smoothed trend oscillator

🔔 2. Arrow Signals (Main chart)

The arrows are generated when the oscillator crosses the zero line:

🟦 BUY Arrow

Triggered when:

• Oscillator moves from below 0 → above 0

📍 Plotted:

• Below the candle (supporting bullish shift)

🔴 SELL Arrow

Triggered when:

• Oscillator moves from above 0 → below 0

📍 Plotted:

• Above the candle (indicating bearish shift)

🧠 Logic summary

The system is essentially:

“When market pressure flips from bearish to bullish (or vice versa), mark it with an arrow.”

So it is a:

• Trend reversal detector
• Momentum flip indicator
• Zero-cross strategy tool

⚙️ Key features

• Uses a period-based range (default 18) to measure price extremes
• Uses recursive smoothing to reduce noise
• Signals are based on zero-line crossover
• Works best in:
  • Trend markets
  • Swing setups
  • M15 – H4 timeframes
