Declaration
The CDemaOnRingBuffer.mqh class file should be placed in the InconRingBuffer folder, which needs to be established in MQL5\include\. Two example files used by the class are attached to this description and should be placed in the same folder. The folder should also contain the classes of CMaOnRingBuffer and CArrayObj.
Class Methods
The calculated indicator data can be accessed from the ring buffer as from a standard array. For instance:
When calculating the DEMA, the Simple Moving Average (SMA) is also computed with the same parameters. We can retrieve the SMA data from the MA ring buffer using the MA method(int index):
Note that indexing in ring buffers follows the same convention as in standard arrays.
Examples
The test_dema_onarrayrb.mq5 file calculates the indicator based on a price time series, demonstrating the application of the MainOnArray() method.
The test_dema_onvaluerb.mq5 file illustrates the use of the MainOnValue() method. It first calculates and draws the DEMA indicator, then draws another DEMA based on the ring buffer of the initial indicator.
Results:
- Test_dema_onarrayrb.mq5 with a ring buffer size of 256 elements.
- Test_dema_onvaluerb.mq5 with a ring buffer size of 256 elements.
This code utilizes the developments of CMaOnRingBuffer, CArrayObj, and CArray.
