NonLagMA with ATR Bands and Control Panel - MetaTrader 5 Script - MT4/MT5 Resources

The control dashboard has the functionality shown in the figure:

One option for defining indicator buffers (and plotting) is to separate data from code and provide the data of each buffer to a single code block. In addition to the data array, an enumeration is defined to access the array via a human-readable index and point to the correct array entry.

This data is then fed by a for loop, which accesses the array and feeds the data to the index setting functions - each function only needs to be entered once:

Likewise, the structure is used to define an array of buffers that can be accessed throughout the program using the same "IndicatorBufferIdx" enumeration value:

structure {
double m_indi_buff[];
} indi_array[k_end_indi_idx]; // Create an indicator buffer according to the defined number of indicator buffers

Like this: indi_array[k_ATR_up_idx].m_indi_buff[shift];

Define and use two classes:

OnCalculate consists of 6 function calls, each of which returns false if processing fails and terminates the OnCalcualte function by returning the number of previously successfully processed bars (the value in the static integer last_prev_calculated):
