Init Sync
Info
The Init Sync is a Library for MetaTrader 5 that if you change the timeframe or the name of the chart symbol in metatrader, all indicators on the chart will be unloaded from the chart and will be loaded onto it again. Unlike MT4, in MT5 the sequence of load/unload is not defined due to its internal architecture.
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 Init Sync
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.

If you change the timeframe or the name of the chart symbol in MetaTrader, all indicators on the chart will be unloaded from the chart and will be loaded onto it again. Unlike MT4, in MT5 the sequence of load/unload is not defined due to its internal architecture.

This feature sometimes causes problems which are not immediately obvious. These problems are related to the fact that OnInit of the new loaded indicator instance can be executed before the OnDeinit of the instance being unloaded.Situations in which this problem is detected, are most often connected with the desire to transmit (explicitly/implicitly) some information from OnDeinit of the older indicator instance to OnInit of the new one. In other words, the new indicator instance should know about the existence of the old one, and should not load until the old instance is unloaded.
This library allows to apply this synchronization to any indicator.
Here is an example of a simple indicator
If you launch this indicator and start switching its chart timeframes or symbol, the alternation of the lines "Init" and "Deinit" will be broken.
If we add the following line at the beginning of indicator code
the proper alternation will be observed.
To apply this property to a desired indicator, add the above structure to its code.
