Rolling Z-Score Trend

A clean, statistical trend & momentum indicator that transforms price into a rolling Z-Score—making regime shifts, momentum bursts, and threshold events easy to spot.

Overview

Rolling Z-Score Trend normalizes price relative to its recent mean and volatility using a rolling Z-Score. This makes market conditions easier to compare across instruments and sessions, because the indicator adapts to changing volatility automatically.

Instead of guessing whether a move is “big enough,” you see how far price is from its statistical average in standard deviations—then get a smoothed signal and clear threshold levels.

How It Works

1. Rolling Mean + Volatility
   The indicator calculates a moving average (mean) and standard deviation over the selected Lookback Period.
2. Z-Score Calculation
   Z-Score = (Price − Mean) / Standard Deviation
   This shows whether price is statistically above or below its recent “normal range.”
3. Smoothing for Readability
   A short EMA is applied to reduce noise and produce a cleaner trend signal.
4. Momentum Background
   A momentum histogram tracks the change in the smoothed Z-Score to highlight acceleration and deceleration.

Key Features

✅ Directional Z-Score Lines (Split Output)

• ZScore Up displays positive values (bullish bias)
• ZScore Down displays negative values (bearish bias)
  This makes direction instantly visible.

✅ Threshold Zones (Overbought / Oversold Framework)
Set an Entry Threshold (e.g., 1.5 or 2.0) and the indicator draws:

• Zero line (neutral regime)
• Upper threshold (+EntryThreshold)
• Lower threshold (−EntryThreshold)

✅ Preset-Based Configuration
Includes quick presets such as:

• Scalping
• Swing Trading
• Trend Following
  Each preset adjusts lookback/threshold inputs for that style.

✅ Momentum Histogram
Shows the rate of change in the smoothed Z-Score (scaled) to help:

• identify momentum bursts early
• detect fading trends
• time entries after a reset

✅ Optional Info Table
A compact table can display:

• current Z-Score value + bias (Bullish/Bearish)
• momentum state (Rising/Falling)
• current threshold level
  You can choose the table position (TopRight, BottomLeft, etc.).

✅ Event Logging (Optional)
Can print messages for key events such as:

• bullish/bearish crossover through zero
• entering/exiting the overbought zone
• entering/exiting the oversold zone

How Traders Use It (Practical)

1) Regime / Bias

• Z-Score above 0 → bullish statistical regime
• Z-Score below 0 → bearish statistical regime
• Frequent flips around 0 → potential range / chop conditions

2) Extremes & Mean Reversion

• Above +threshold → statistically stretched (often “overbought”)
• Below −threshold → statistically stretched (often “oversold”)
  Used for:
• mean-reversion setups (fading extremes)
• confirming strong trends (holding beyond thresholds)

3) Momentum Timing

• Momentum rising → acceleration
• Momentum falling → deceleration
  Useful for managing entries/exits and avoiding late signals.

Best Markets / Timeframes

Works well across indices, FX, metals, and crypto. The volatility-normalized approach helps it adapt to different instruments and conditions.

Suggested Starting Settings

• Scalping: Lookback 10–14, Threshold 1.0–1.4
• Swing: Lookback 20–30, Threshold 1.5–2.0
• Trend: Lookback 35–50, Threshold 2.0–2.5
