MQL5 wizard has no OrderSend() but still opening a trade. How does it work

[Abdul Arief Bogie Ardianto]

i have some experience in MQL4 and still learning MQL5 language. I understand most basic code conversion MQL4 to MQL5.

Recently i learn that there is a MQL5 Wizard to create an EA automatically. Tried to make it create a simple EA to open buy if RSI>80 and sell if RSI<20. It works but i have no idea how it open a new trade because it has no OrderOpen Ctrade or OrderSend() Trade Operation Types. It only shows ExtExpert.OnTick();. Currently i only know these 2 methods opening a new trade, still figuring out which one i'm going to explore. Ctrade seems more simple but i feel like it skips many important things but i'll see the difference later.

So the question is: How this code works by opening a BUY and SELL trade? You may also give me an article about it.

You can see and study it in the Expert.mqh file
