int aperiod - The indicator period.
enum_ma_method amethod - The Moving Average method.
The solve() method is called within the solve() 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 adatahigh[] - The buffer containing the high data for indicator calculation.
double adatalow[] - The buffer containing the low data for indicator calculation.
double ap[] - Intermediate buffer for the positive component.
double am[] - Intermediate buffer for the negative component.
double aps[] - Intermediate buffer for the smoothed positive component.
double ams[] - Intermediate buffer for the smoothed negative component.
double ademarker[] - The buffer where the calculated indicator value will be stored.
Additional Methods:
int barsrequired() - Returns the minimum number of bars required for indicator calculation.
string name() - Returns the indicator name.
A sample indicator demonstrating the application of the CDeMarkerOnArray class is available in test_demarkeronarray.mq5.
The CDeMarkerOnArray file must be placed in the MQL5\Include\inconarray folder of your terminal data folder. You may need to create the inconarray folder.
The CMaOnArray class from the incmaonarray file is required for this class to function correctly. This class can be found separately.
The DeMarker (DeMarker) technical indicator is based on comparing the current period's maximum with the previous period's maximum.
