Ticker FATL
Download script
This script is a specialized technical analysis tool designed to track and visualize specific price dynamics within the MetaTrader platform. It operates by monitoring the real-time "Bid" price of an asset and performing complex mathematical calculations to generate two distinct data lines on a separate indicator window.
Core Functionality
Price Tracking and Memory The script continuously monitors the live market price. To ensure it only processes meaningful movement, it ignores "noise" by checking if the current price has actually changed compared to the previous tick. When a change occurs, the script updates its internal memory, shifting older data points back to make room for the newest price information. It maintains a history of these values up to a user-defined limit (defaulting to 1000 bars).
The Calculation Logic The primary purpose of this tool is to generate the "FATL" value. This is achieved through a sophisticated weighted calculation:
- Data Requirements: The script waits until it has collected at least 38 unique price points before it begins providing any data for the FATL line.
- Weighted Averaging: Once the threshold is met, it applies a specific set of mathematical coefficients (weights) to the most recent 39 price points. Some prices are added to the calculation, while others are subtracted based on these precise multipliers.
- Dynamic Output: This process results in a derived value that reflects a specific trend or correlation of the recent price history, providing a secondary metric for the user to observe alongside the raw price data.
Visual Representation
The tool displays two distinct lines in a separate window below your main trading chart:
- Ticker: A visual representation of the primary price movements as they are captured by the script.
- FATL: The secondary line, which represents the result of the weighted mathematical formula.
By observing these two lines simultaneously, users can compare the raw "Ticker" movement against the calculated "FATL" output to identify specific patterns or behaviors in the market's price action.
