Is This Tutorial Wrong ?

I am reading a MQL4 tutorial and I think I have found something very very wrong!!!
The tutorial link:
http://innovationstartups.wordpress....opment-course/
PS: It looks like Coders guru wrote the tutorial, as it says in lession3 string str1 = “Hello world1, with you coders guru”;

+ Addition operator
A = B + C;
Description Add A to B and assign the result to C.

- Subtraction operator
A = B - C;
Description Subtract C from B and assign the result to C.

For the description of addition hes says; Add A, when A is the answer! also he says assign the result to C, when again A is the answer not C! It looks like you add C to B and assign the result to A.

In the descripton for subtraction he only uses the letters C, B and again C (I thort that addition and subtraction were opposites).

If the descriptions were opposite...
As the description for addition is: Add A to B and assign the result to C.
Subtraction should be: Subtract A from B and assign the results to C.

any way mabey one or both of the descriptions are wrong, I think it goes like so:

+ Addition operator
A = B + C;
Description Add C to B and assign the result to A.

-

- Subtraction operator
A = B - C;
Description Subtract C from B and assign the result to A.

The sum looks like it is written left to right as the answer is at the start. At school I did maths like this C-B=A with the answer at the end. This logic does not seam to apply with this sum if you do the addition with it, ie: C+B=A (If ABC is 123 youve just said 3+2=1 and even my little brother knows thats wrong!!!) sorry to 'Coders guru' if am wrong I am new at programming learning every day but this does not help. It is confusing, and has killed my brain for tonight.

for that kind of simple maths...i think the erro is by typo error...
it happens a lot in programming...

I do find one error code by coder guru...but i realise it is may be a typo erro...but the programming idea is correct...
how to know?...when compile you find error, try correct it, compile again, error gone, try run, running fine than it is ok

hmm.. yes I see what you are saying but I need to understand how this works in order to progress in my learning.

he has given two different explanations for this....

One mabey correct but which one? or are they both wrong I dont know! I am new reading a messed up tutorial, other tutorials are like translated from russian and the MQL4 manual is very short in what it says:
Difference of values i = j - 3;
Not enough to make me understand when i am trying to picture how an indicator works using the Arithmetical operations, esspecialy when adding and subtracting complex fuctions.

does it do sums backwards or what?

Look I am adding lables and changing the names of functions to remember what they do and how they work:

I am learning fast but on the order and presidence of functions within sums I am now stuck!

This Needs to be eplained in a tutorial some where other wize how will people learn?

If you are learning programming I suggest starting with a book or beginner's online course about C++. This way you will find much better learning material and will become a good programmer both easier and faster. If you learn one programming language, you will very easily understand any other (including MQL)

Ok that is brilliant advice can you recomend one because I am unsure what would be applicable.

Thank you.

MQL4 is probably the easiest programming language to start with.
And those are clearly typos

I would actually suggest 'the c programming language', books on c++ will be cluttered with c++ stuff which is not applicable to mql (classes, templates, stl), mql is much closer to c than c++.

What should I read Please?

when i started to code i was reading some nice tutorial... its 5 parts, about general stuff and later on about writing indicators and graphical objects and stuff like that... its really good and helped me a lot, thats why i recommend it. but at the same time i have to warn you to keep your eyes and your mind open as it also contains some typos, like so many tutorials... but i dont worry about you since ive seen that you think while u read (a=b+c is not sum of a and b is assigned to c)

hope this helps to answer some questions, now and in future...

Have you looked at CodersGuru's lessons or are you looking for more advanced information?

Carry on tryin to learn mql4 as that is the main language you want to learn and it is the easiest to pick up.
You could try learning c or SQL and it will help with your understanding of programming languages, but mql4 is basically SQL, its just a specific variation on it. U might as well stick with it.
Just a couple of tips that helped me is:

Try to think like a computer would think.
You have to tell the computer what to do because it doesnt know what to do untill u tell it.

It will read your programme like you read a book, i.e. from left to right and top to bottom. (basically, although it can jump from place to place but dont worry about that too much, just imagine it like a book).

There are certain words you will type that the programe will automatically know what to do, these are pre-programmed functions.
An example in mql4 is iHigh(), or iClose().

Anything in brakets like above will require you to give it a value or rather a variable.

Try not to other think it, its not as complicated as it first appears.
Try and do the basic tutorials and give it time. Go through them step by step as this is the quickest way to learn is by doing.

Then make your own basic programme. For example make your programme make an alert when the last bar is a bearish candle and tell you so.

Finally it takes a while to pick up programming dont expect results over night. Start at the basics and increase your knowledge as you go.

(Nvwine)I was reading this one..http://innovationstartups.wordpress....opment-course/


(GCash) lol i have tryed to take out the typos from that tutorial! my work is attached next...

Same tutorial.
Most has been posted here but a couple new links.

Yes, you are right, mql is closer to c. I recommended C++, because majority of books for beginners start from general programming knowledge and jump to object oriented programming later. Also if I remember correctly MQL5 will be object oriented programming language, so more knowledge is never bad

As regards discussion regarding easiest language, I would say that there are no difficult languages. What matters is the determination to study. Whatever language you choose, it will teach you general programming principles.

Ok learn about multidimensional arrays, subexppressions, classes etc cause its just as easy as trying to learn the basics in mql4.

My version of the tutorial (simple version) it wont upload its 1.17mb. its not just typos. all of the sentances are grammaticaly wrong and i am very dyslexic this does not mean stupid or that i cannot learn but i cant read if there are mistakes on every single line i will have a bloodvessle blow up in my brain. It must have been translated from russian or something seriosly i cant read this with my learning difficulty....i can lear to program i know that i can ijust need something readable!

i dont know if this has been posted , try here.

thank you. this has the original typo + Addition operator A = B + C; Add A to B and assign the result to C. but now I must be annoiying so i will change what i am asking because it looks like i have got all the mql4 lessions.


Q) what would be a good method of arranging the code in your indicator i will attached the one that i am working on. as you can see i have tryed to give self explaitory names to every thing but, it now seams to cofuse the rest of the code.

i was thinkin of calling all these things A,B,C,D,E1,E2 ect...
and then making the definitions at the top like a refence list or dictionary.

is this a good idear or have you a better one?
