s Token
Info
The s Token is a Library for MetaTrader 5 that the script contains a class, that can be used to solve mathematical and logical expressions, defined as string. The script has two classes: cTokenBase and cToken (a member of CTokenBase).
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 s Token
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.

The script contains a class, that can be used to solve mathematical and logical expressions, defined as string.The script has two classes: cTokenBase and cToken (a member of CTokenBase). The cTokenBase class must be configured before its use (see below).
The following MQL5 are supported: , , , , , , , , , , , , , , , , , , .
Logical and math operations: /, %, *, +, -, >, <, >=, <=, ==, !=, &&, ||.
The expression may contain numbers, including double numbers, user variables and user arrays. If you will use the user's variables and arrays, you need to add functions, that returns the values of these variables and arrays. The functions should be added into the cTokenBase class.
The user variables and arrays are named with letters (the case isn't important), the array elements are defined as follows: e[0], e[1], f[0], f[1].
Examples:
How to configure cTokenBase class
It's neccessary to register the name of the user variables and arrays. It must be done in the UsersVariables() function. The list of user variables/arrays contain the names, separated by ";".
2. You need to add a call of the corresponding function to the UserFunc(string FuncName) function:
3. Add functions for all of the user's variables:
4. Add call of the corresponding function (dependent on ArrName) to the UserArray(string ArrName,int aIndex) function. The index of array element is specified in aIndex variable.
5. Add functions for each of the arrays:
Use of the class
1. Declare an external input variable for the expresssion:
2. Delcare a cToken class variable on the global level:
3. Initialize class with the expression.
4. Call SolveExpression() method
The class can be used to solve several expressions, just use the several instances of cToken class:
In this case all the class instances will use the same user variables and arrays (declared in cTokenBase class)
You can add your functions.
Adding new functions to cToken class
Register a new function. It must be done in the function.
Add the calculation code to the SolveFunc(string Func,string & aRes[]) function. The function arguments are located in aRes[] array. The number of arguments isn't limited.
