Check if there are any new bar
This tool for MetaTrader 5 is specifically engineered to streamline your trading operations. This library provides a collection of modular, reusable code. It is utilized by developers to organize common functions, allowing for the integration of complex logic across multiple Expert Advisors, indicators, or scripts without the need for code duplication.
How to Setup and Use Check if there are any new bar
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.
Description & Settings
1、There is only one class function without additional variables. Please declare class CCheck before use
2、Program variables are used to store corresponding data, while historical bar variables need to be statically modified for data storage
3、This is the function to obtain the latest bar time. Using this function, the system runs the fastest, so it is used. When it returns False, the function will not exit, and if necessary, check the error code.
4、When used for the first time, initial values will be assigned to the storage location of historical data for subsequent comparison
5、Comparing the old and new time columns, if there is a difference, it indicates that a new bar has been generated and returns true. If the time is the same, there are no new bar, return false
