Usage:
init()
This method is called in the OnInit() function with the following parameters:
int aperiod
- The period for the efficiency ratio calculation.
int afastperiod
- The minimum period for the Exponential Moving Average (EMA).
int aslowperiod
- The maximum period for the Exponential Moving Average (EMA).
solve()
This method is called in the OnCalculate() 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.
double adata[]
- The data buffer for the indicator calculation.
double aama[]
- The buffer to store the calculated AMA value.
Additional methods:
int barsrequired() - Returns the minimum number of bars required for the indicator calculation.
string name() - Returns the name of the indicator.
The test_amaonarray.mq5 file is a sample indicator demonstrating the use of the CAMAONARRAY class. The incamaonarray file must be placed in the MQL5\Include\Inconarray directory of your terminal's data folder. You may need to create the Inconarray folder.
The (AMA) technical indicator is used for constructing a moving average that exhibits low sensitivity to price series noise and minimal lag for trend detection. This indicator was developed and described by Perry Kaufman in his 2026 book "Smarter Trading".
