What are the Ask, Bid, Bars, Close, Open, High, Low, Time and Volume?
Variables?
It was not mentioned in your lessons. May you describe about that?
What is the difference between Ask - Bid and other above mentioned variables?
Current bar is Bars = 0. Right?
And previous bar is Bars = 1.
And what is Bars = -1. Is it 10 or Is it the future bar?
Yes, your first two assumptions on "Bars" are correct. But there is no value "-1", if there really was one, you had found a perfect trading system. Looking ahead one bar into the future and buy/sell accordingly ;-).
i have a special Question to MQ4, maybe you can help me
i have a global integer Variable in an EA
if i start the Programm the Variable will be initialice to 0 (i=0)
if i call the properties and then go back via OK. The Init() will be called
but the global variable i is not initialiset to 0
the variable has allways stored the old value.
the definition of the GLOBAL variable is:
int i=0;
on Solution can be to set the Variable to 0 in init()
but is there an other way?

If you want that variable to change to 0 every time you initialize the EA/indicator/somethingelse? you set it to 0 in the init() section. Or you change it to 0 in some other part. Or you use local variable instead of a global one. There are many-many ways to fix a problem as long as you know where you want to end up.
Thanks!
