In the previous articles, we started creating a large cross-platform library simplifying the development of programs for
MetaTrader 5 and MetaTrader 4 platforms. In the eighth part, we implemented the class for tracking order and position
modification events. Here, we will improve the library by making it fully compatible with MQL4.
Improving the library
In the DoEasy library root folder, create the new ToMQL4.mqh include file. Here we will describe all
necessary constants and enumerations for MQL4.
Include it to the Defines.mqh file
for MQL4 compilation at the very beginning of the Defines.mqh listing:
After that, the entire MQL4 library will be able to see what is written in the ToMQL4.mqh file during compilation.
Let's move to the very beginning of the error list in the Errors tab of the Editor's Toolbox by pressing NumPad Home or by simply scrolling up
to the very start. Double-click the very first error:
