How to Install and Use Calculating Chaikin Oscillator Values with the CCHOONARRAY Class
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.

- int afastperiod: fast MA period- int aslowperiod: slow MA period
- enum_ma_method amethod
Solve() method with the following parameters is called in the function:
- const int aratestotal: rates_total variable from the OnCalculate() function parameters
- const int aprevcalc: prev_calculated variable from the OnCalculate() function
- double adatahigh[]: buffer with high data for indicator calculation
- double adatalow[]: buffer with low data for indicator calculation
- double adataclose[]: buffer with close data for indicator calculation
- double adatavolume[]: buffer with volume data for indicator calculation
- double & atmpad[]: intermediate auxiliary buffer
- double & afastad[]: auxiliary buffer for fast MA
- double & aslowad[]: auxiliary buffer for slow MA
- double & acho[]: buffer with calculated value
Additional methods:
- int BarsRequired(): returns the minimum number of bars for indicator calculation
- string Name(): returns the line with the indicator name
The test_choonarray.mq5 sample indicator demonstrates the application of the CCHOONARRAY class. The incchoonarray file must be placed in the MQL5\Include\incchoonarray folder of the terminal data folder (the incchoonarray folder must be created).
Chaikin's Oscillator (CHO) is the difference of moving averages of the Accumulation/Distribution Line.
