Attempted to install MetaTrader 5 with wine on linux, loving the irony of "... please install using Window 7 ... trading requires maximum security" bahaha

Metatrader 5 mql editor idiots. I have made changes, saved file and it is empty. I can only undo changes, which makes it become as it was before changes. Fucking idiots.

Later I see when I open the file from windows browser in notepad++ - tthe changes exists. What a fuck bullshit. So at least they exists but idiots show same file in metaeditor with old changes after undo or empty if not undo.

Again idiotic language or documentation.
I want to just draw stupid arrow on chart. Took code from example. It just does not draw. No fucking error.

mql language.

Just in case somebody knows:

ObjectCreate(name, OBJ_TEXT, 0, 0, 0, 0, 0);
ObjectSetText(name, name);
ObjectSet(name, OBJPROP_COLOR, Green);
//ObjectSet(name, OBJPROP_TIME1, Time[0]+2*Period()*60);
ObjectSet(name, OBJPROP_TIME1, Time[0]);
ObjectSet(name, OBJPROP_PRICE1, High[0]);

this code is in onTick() method.

It looks like there are tons of posts on how to do it but nothing works what I have tested.

I really from time to time think about writing some trading bot but probably thats why I stop doing it because it takes so much time to do simple things with this language.

I could do with languages which I know - php, js , but still if i want to run it with brokers who have metatrader, I would need to know mql language :(

Metatrader and its forum. I have asked a question 2 weeks ago, simple one. Just want to know how it calculates loss in backtest because it does not match my calculation. And nobody is answering. Then I go add comment to support thread, and my comment was deleted twice! wtf. And I cannot find in documention or in other forums my answer. Need to try stackoverflow maybe. In official forum they should know best. And it looks like it is active forum.

Why the fuck is MQL C++ based? Why not make a simple scripting language which gets interpreted by your application? I don't want to write headers and definitions constantly, I'm just trying to write a trading indicator ffs
