How to Install and Use CTemaOnArray Class for Triple Exponential Moving Average Calculation
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 CTemaOnArray class is designed for calculating the Triple Exponential Moving Average (TEMA) on an indicator buffer.Also recommended: class calc frac - custom bar count for fractal detection - similar library with strong performance on MetaTrader 5.
Usage:
The init() method is called within the indicator's function with the following parameters:
int aperiod: The indicator period.
enum_ma_method amethod: The Moving Average method.
The solve() method is called within the function with the following parameters:
const int aratestotal: The rates_total variable from the oncalculate() function parameters.
const int aprevcalc: The prev_calculated variable from the oncalculate() function parameters.
double adata[]: The buffer containing the data for indicator calculation.
double am1[]: An intermediate buffer for calculations.
double am2[]: An intermediate buffer for calculations.
double am3[]: An intermediate buffer for calculations.
double atema[]: The buffer containing the calculated indicator values.
Additional Methods:
int barsrequired(): Returns the minimum number of bars required for indicator calculation.
string name(): Returns a string with the indicator name.
The test_temaonarray.mq5 file demonstrates how to use the CTemaOnArray class. The inc temaonarray file should be placed in the MQL5\Include\Inconarray directory of your terminal data folder (you may need to create the Inconarray folder). The CMAOnArray class is also required for this class to function correctly.
Technical Indicator (TEMA):
The Triple Exponential Moving Average was developed by Patrick Mulloy and published in the "Technical Analysis of Stocks & Commodities" magazine. Its calculation principle is similar to other moving averages, but the name "Triple Exponential Moving Average" does not fully reflect its algorithm. TEMA is a unique blend of single, double, and triple exponential smoothing averages, offering a smaller lag than each of them individually.
