Mql5 code idea of indicators for beginners? - page 2

Yes but they just implement iRSI here and nothing is revealed about the inside workings of iRSI (maybe because it's proprietary code)

In here you will see an actual RSI algo, he does not use iRSI, he does does the function from scratch: https://www.mql5.com/en/code/20650

the code is very cryptic though and not understandable.

It would be nice to understand this "algo scaling":

 return(50.0*(workRsi[r][z+_change]/MathMax(workRsi[r][z+_changa],DBL_MIN)+1));
