Download script
This script is a trend-following technical indicator designed for the MetaTrader trading platform. Its primary purpose is to identify market momentum by analyzing multiple timeframes simultaneously and providing visual cues (arrows) on the chart to signal potential shifts in price direction.
Core Logic Overview
The indicator operates on a multi-layered analysis system. Rather than looking at just one timeframe, it evaluates three different timeframes (defined by the user) to ensure that the trading signals are consistent across short, medium, and long-term views.
Analysis Components
To determine the current market trend, the script processes two main types of data:
1. Moving Average Alignment: The script monitors five different Simple Moving Averages (SMAs) across all three selected timeframes. It checks whether these averages are currently sloping upward or downward. If the majority of these averages are trending in the same direction, it adds "weight" to that trend.
2. Awesome Oscillator (AC) Analysis: The script incorporates the Awesome Oscillator logic to detect momentum shifts. It looks for specific patterns in the AC values—specifically identifying "peak" or "valley" formations where the momentum is accelerating or decelerating. When these conditions are met, they significantly increase the weight of the trend signal.
Signal Generation
The indicator uses a weighted scoring system (represented as "ResUp" and "ResDown").
- Bullish Signals: If the combined weight of the moving averages and the oscillator signals across all three timeframes favors an upward move, the script identifies a bullish trend.
- Bearish Signals: Conversely, if the weights favor a downward move, it identifies a bearish trend.
The script specifically looks for "trend flips." It will only display a visual arrow when the market transitions from one state to another (e.g., from a confirmed downtrend to a confirmed uptrend). This helps filter out "noise" and ensures that arrows are only plotted at significant turning points.
Visual Features and Information
- Chart Arrows: The tool places blue arrows for potential buy signals and red arrows for potential sell signals directly on the price chart.
- On-Screen Commentary: If enabled, the script provides a real-time text readout on the chart. This display includes:
- The current trend direction (Up or Down).
- The number of bars since the last trend change.
- A calculated score for both upward and downward momentum across the various timeframes analyzed.
Summary for the User
In essence, this tool acts as a "confluence" indicator. It avoids making a decision based on a single piece of data; instead, it waits until multiple moving averages and momentum oscillators across different timeframes all agree on a direction before notifying you with an arrow.
