Is This Tutorial Wrong ?

Quoting fry2010
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.
WHA???

MQL is nothing like SQL. You would be wasting your time with an SQL book.

As others have posted, get a book on C or even on Java and you will be much better off. Dont bother with an SQL book.

Quoting bamben
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...
I took a quick look at your code and I think somebody already mentioned it but don't over complicate things. Take a look at some of the EA's and indicators posted by someone like mladen (maybe he's over at forex tsd, can't recall) and see how he arranges his code and names variables and functions.

The other suggestion, to read programming books, is a good idea too. The only thing I'd suggest different is to read a visual basic or similar type book. It's MUCH easier to understand than a C++ book and will give you just as much of a kickstart into MQL4 as anything else. Without the 'busted bloodvessel'

You need to get a solid naming style sorted out too. Choose one and stick with it. There are far too many different styles in your code at the moment. Try to make variable names descriptive so that it's easy to see at a glance what a variable or function does. I see in your code at the moment you have variables like p to hold the period. What I would have done is name it dPeriod. That way you can see at a glance it's a double and it holds the Period, simple!

Just to repeat myself, keep it simple and don't over complicate it. You'll get there!

Good luck
