Indicator Initialization Synchronization for MT5
Info
The Indicator Initialization Synchronization for MT5 is a Library for MetaTrader 5 that synchronization of indicator initialization and deinitialization in mt5in metatrader 5 (mt5), changing the chart symbol or timeframe causes all indicators to be reloaded. Unlike MT4, MT5's internal architecture does not guarantee a specific order for indicator deinitialization and reinitialization.
Usage
This tool is typically used for enhancing chart analysis and decision making.
Platform
This Library works exclusively on MetaTrader 5 (both build 600+ and newer versions).
Setup
Place the downloaded file in MQL5/Libraries folder via File ? Open Data Folder in MetaTrader 5.
How to Install and Use Indicator Initialization Synchronization for MT5
1. Storage: Place library files in the MQL/Libraries directory to ensure they are accessible to your projects.
2. Implementation: Include the library in your code using the #import directive, ensuring you match the exact function names and parameters.
3. Compilation: Ensure the library is present in the directory before you compile your main EA or script, as the compiler links them during this phase.
4. Management: Keep libraries organized in sub-folders if you manage many custom functions to maintain a clean project structure.
Frequently Asked Questions
Q: What is a library file used for? A: Libraries store reusable code modules, allowing you to centralize common logic used by multiple EAs or indicators.
Q: Is a library executable? A: No, libraries are non-executable files containing functions; they must be imported into an EA, indicator, or script to function.
Q: Can I update a library while the platform is running? A: You should compile your EA or script after updating a library to ensure the latest code changes are integrated.

Synchronization of Indicator Initialization and Deinitialization in MT5In MetaTrader 5 (MT5), changing the chart symbol or timeframe causes all indicators to be reloaded. Unlike MT4, MT5's internal architecture does not guarantee a specific order for indicator deinitialization and reinitialization.

This behavior can lead to subtle issues, particularly when an indicator's `OnInIt` function executes before the previous instance's `OnDeInit` has completed. Such problems commonly arise when attempting to transfer information from an older indicator instance to a new one during initialization. The new instance needs to acknowledge the old instance and should not load until the old one is fully unloaded.
This library provides a mechanism to synchronize these events for any indicator.
Consider a basic indicator. If you switch its chart symbol or timeframe, the sequence of 'init' and 'deinit' calls will be disrupted.
By incorporating a specific structural element at the beginning of the indicator's code, the correct initialization and deinitialization sequence will be maintained.
To apply this synchronization to any indicator, add the provided structure to its source code.
