IncIchimokuOnArray – library MetaTrader 5

The CIchimokuOnArray class is intended for calculation of Ichimoku (Ichimoku Kinko Hyo) values on indicator buffers.

Usage:

The Init() method with the following parameters is called in the OnInit() function of the indicator:

• int aPeriodTenkan is the Tenkan period;
• int aPeriodKijun is the Kijun period;
• int aPeriodSenkou is the Senkou period;
• bool aABShift determines whether to calculate the SpanA and SpanB lines with shift or not. If the value is True, the SpanA and SpanB lines are shifted during calculation; in this case, there will be no future data for these lines. If the value if False, shift the SpanA and SpanB lines using the PlotIndexSetInteger() function with the PLOT_SHIFT identifier.

• const int aRatesTotal is the rates_total variable from the OnCalculate() function parameters;

• double aDataHigh[] is the buffer with the High data for the indicator calculation;
• double aDataLow[] is the buffer with the Low data for the indicator calculation;
• double & aTenkan[] is the buffer with calculated values of the Tenkan line;
• double & aKijun[] is the buffer with calculated values of the Kijun line;
• double & aSpanA[] is the buffer with calculated values of the SpanA line;
• double & aSpanB[] is the buffer with calculated values of the SpanB line.

• int SpanABShift() returns the shift of the SpanA and SpanB lines;
• int BarsRequiredTK() returns the number of bars required for calculation of the Tenkan and Kijun lines;
• int BarsRequiredAB() returns the number of bars required for calculation of the SpanA and SpanB lines;
• string Name() returns a string with the indicator name;
• string NameT() returns a string with the Tenkan line name;
• string NameK() returns a string with the Kijun line name;
