Calculating value for Ichimoku on RSI

[Deleted]  
I want to code an EA with Ichimoku on RSI in the same window. I have been searching for the right function to calculate the value of iIchimokuonArray, is it possible? 

All articles i have been researching refer me to iMAonArray found in mt4. Can some1 help me with the function for Ichimoku on RSI in mt5. 

Unfortunately i used my phone to write this topic i could have attached what i have coded so far, defining ichimoku and rsi, copying buffers and setting array as series.
