Usage:
init()
This method is called during initialization and accepts the following parameter:
int aperiod
- The period used for calculating the Efficiency Ratio.
solve()
This method is called during calculation and accepts the following parameters:
const int aratestotal
- The total number of bars available, typically obtained from the `rates_total` parameter in the `OnCalculate()` function.
const int aprevcalc
- The number of previously calculated bars, typically obtained from the `prev_calculated` parameter in the `OnCalculate()` function.
double adata[]
- The data buffer containing the indicator's input data.
double aer[]
- The output buffer where the calculated Efficiency Ratio will be stored.
Additional Methods:
int barsrequired()
- Returns the minimum number of bars required for the indicator to perform its calculations.
string name()
- Returns the name of the indicator as a string.
A sample indicator, `test_eronarray.mq5`, demonstrates the application of the Ceronarray class. The `inceronarray` file should be placed in the `MQL5\Include\inconarray` directory within your MetaTrader terminal's data folder. If the `inconarray` folder does not exist, please create it.
