Need help creating EA MT4

[FD45D13D]

Hye there. I apologize if this has been asked before. I am a beginner in creating EA and would appreciate it if someone can point it out to any youtube channel or websites that teach me how to write a script in meta editor for free. I would like to create an ea with 3 indicators in indicator chart, specifically custom RSI, custom stochastic oscillator and custom MA. By custom, i meant that i can change the value for example, the period in RSI to 5 from default 14 and specified it in editor. And when all conditions are met, for example when RSI level hits 85 n above, stochastic and MA levels hit 80, it will create alarm/alert notifications that will be send to phone to inform to sell. And vice-versa for buy. I prefer to do buy/sell order manually but if it can be done in the script, i will gladly learn it as well for future reference.

Thank you very much for reading this and for your help. Have a good day.
