Stochastic Oscillator Calculation on Arrays
Info
The Stochastic Oscillator Calculation on Arrays is a Library for MetaTrader 5 that the cstochasticonarray class is designed for calculating indicator buffers directly on provided arrays. Initialization:The init() method is called during initialization with the following parameters:int stperiodk - The period for the K line.
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 Stochastic Oscillator Calculation on Arrays
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.

Initialization:
The init() method is called during initialization with the following parameters:
int stperiodk - The period for the K line.
int stperiodd - The period for the D line.
int stperiods - The period for the S line.
enum_ma_method stmethod - The smoothing method for the signal line.
Calculation:
The solve() method performs the calculation using the following parameters:
const int rates_total - The total number of bars available, typically from the OnCalculate() function.
const int prev_calculated - The number of bars calculated in the previous call, typically from the OnCalculate() function.
double dataClose[] - The array containing closing prices for the calculation.
double dataHigh[] - The array containing high prices for the calculation.
double dataLow[] - The array containing low prices for the calculation.
double & stochMain[] - The array where the calculated main line (K line) will be stored.
double & stochSignal[] - The array where the calculated signal line (D line) will be stored.
Additional Methods:
int barsRequiredSignal() - Returns the minimum number of bars required to calculate the signal line.
int barsRequiredMain() - Returns the minimum barss required to calculate the main line.
string name() - Returns the name of the indicator.
Example Usage:
The test_stochasticonarray.mq5 file demonstrates how to use the CStochasticOnArray class. Ensure the inconarray file is placed in the 'mql5\include\inconarray' directory within your MetaTrader terminal's data folder. You may need to create the 'inconarray' subfolder.
Dependency:
The CMaOnArray class from the incmaonarray file is required for the proper functioning of CStochasticOnArray.
Indicator Description:
The Stochastic Oscillator is a technical momentum indicator that compares a security’s closing price to its price range over a given period. It is typically displayed as two lines: the main line (K) and the signal line (D).
