Dear Developers,

I am looking for an experienced MQL5 developer to integrate Match-Trader using its API. The scope of the project involves developing two specific functions as outlined below:

string Login(string _dx_server, string _dx_login, string _dx_password)
{
    return(Token); 
}



bool Refresh_token(string _previous_token)
{
    return; 
}

Login Function

Refresh Token Function

Refresh_token - This function need to refresh previous token and keep alive. 

Key Requirements

Only developers who have prior experience working with the Match-Trader API should apply. Please ensure you have tested the functions thoroughly before submitting them for my review.
