TEMA_CUSTOM - indicator for MetaTrader 5

The Triple Exponential Moving Average (TEMA) technical indicator with advanced features of setting input parameters. The Triple Exponential Moving Average (TEMA) technical indicator was developed by Patrick Malloy He published it in the Technical Analysis of Stocks & Commodities journal.

This indicator can be used instead of the usual moving averages. Triple Exponential Moving Average (TEMA) is a combination of one exponential moving average, a double exponential moving average and a triple exponential moving average, which provides less delay than any of these three averages individually.

Indicator input parameters:

input Smooth_Method MA_Method1=MODE_EMA_; // Method of averaging of the first smoothing
input int Length1=12; // Depth of the first smoothing
input int Phase1=15;  // Parameter of the first smoothing
//---- for JJMA within the range of -100 ... +100 it influences the quality of the transition process;
//---- for VIDIA it is a CMO period, for AMA it is a slow average period
input Smooth_Method MA_Method2=MODE_EMA; // Method of averaging of the second smoothing
input int Length2 = 5; // Depth of the second smoothing
input int Phase2=15;   // Parameter of the second smoothing
//---- for JJMA within the range of -100 ... +100 it influences the quality of the transition process;
//---- for VIDIA it is a CMO period, for AMA it is a slow average period
input Smooth_Method MA_Method3=MODE_EMA; // Method of averaging of the third smoothing
input int Length3 = 5; // Depth of the third smoothing
input int Phase3=15;   // Parameter of the third smoothing
//---- for JJMA within the range of -100 ... +100 it influences the quality of the transition process;
//---- for VIDIA it is a CMO period, for AMA it is a slow average period
input Applied_price_ IPC=PRICE_MEDIAN; // Price constant used for the indicator calculation
input int Shift=0; // Horizontal indicator shift in bars
input int PriceShift=0; // Vertical indicator shift in points

It should be noted that Phase1, Phase2 and Phase3 parameters have completely different meaning for different smoothing algorithms. For JMA it is an external Phase variable changing from -100 to +100. For T3 it is a smoothing ratio multiplied by 100 for better visualization, for VIDYA it is a CMO oscillator period and for AMA it is a slow EMA period. In other algorithms these parameters do not affect the averaging. For AMA the fast EMA period is a fixed value and is equal to 2 by default. The ratio of raising to the power is also equal to 2 for AMA.

The indicator uses SmoothAlgorithms.mqh library classes (copy it to <terminal_data_folder>\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".

Originally this indicator has been written in MQL4 and was first published in the Code Base on 19.06.2015.
