The XP Moving Average is a versatile technical analysis tool designed to help traders identify trends and potential entry or exit points in the financial markets. Rather than being limited to a single calculation method, this script acts as a multi-functional framework that can generate several different types of moving averages depending on your preferences.

Core Functionality

The primary role of this script is to calculate a specific "base" moving average from the market price. It provides users with a wide variety of mathematical models to choose from, including:

  • Standard Models: Simple (SMA), Exponential (EMA), Smoothed (SMMA), and Linear Weighted (LWMA).
  • Advanced Smoothing Models: Double Exponential (DEMA), Triple Exponential (TEMA), Hull Moving Average (HMA), and Jurik Moving Average (JMA).
  • Specialized Indicators: T3 Moving Average, DECEMA, and the SALT indicator.

Trend Detection Logic

Beyond just drawing a line on your chart, the script performs an active analysis of price momentum. It compares the current moving average value against a calculated "short-term" average of itself (based on a user-defined step period). This comparison creates two distinct visual signals:

  • Upward Momentum: When the current price trend moves above its own short-term average, the script identifies potential bullish movement.
  • Downward Momentum: When the current price trend falls below its short-term average, it identifies potential bearish movement.

Visual and Alert System

To make these signals actionable for the user, the script includes several automated notification features:

  • Visual Cues: The script automatically places arrows on the chart to highlight the exact moment a trend shift occurs. These are color-coded (Aqua for upward signals and Magenta for downward signals) to ensure they are easily distinguishable.
  • Dynamic Spacing: The script includes "shift" logic that adjusts the placement of these arrows based on the timeframe you are viewing, ensuring the symbols remain readable whether you are looking at 1-minute charts or monthly charts.
  • Real-Time Notifications: You can enable sound alerts to notify you instantly when a signal appears. Additionally, there is an optional email alert system that can send a notification directly to your inbox whenever a trend change is detected.

User Customization

The logic is designed to be highly adaptable. Users can modify the calculation period (how far back the average looks), the specific type of moving average used for the base calculation, and which price data (Open, High, Low, Close, etc.) the script should prioritize. This allows the tool to be tailored to different trading styles, from scalping fast movements to identifying long-term macro trends.

Dependencies

JMA

A sophisticated adaptive trend-following indicator that utilizes non-linear filtering, logarithmic scaling, and dynamic phase adjustments to minimize lag while preserving signal integrity.

JMA

T3MA

This indicator calculates a high-order smoothed moving average by recursively applying exponential averages and weighting them with a customizable volume factor to reduce noise while preserving price trends.

T3MA

HMA

This indicator applies a dual-weighted linear moving average formula coupled with a square root period smoothing to minimize price lag while maintaining high sensitivity to momentum shifts.

HMA

DECEMA_v1

The indicator calculates a high-order polynomial smoothing of an Exponential Moving Average to reduce noise and identify trend momentum.
