Dear. There is a great desire to use in the EA code the values of the TMA indicator, which is MTF. In the comments mladen is mentioned as the author. I do not try to fool around, one thing is shown on the chart, but values returned in the tester are different, totally different. Do I have a right to life and hope to find the answer here? :)

Thanks in advance!

Good afternoon!

Question about arrays, in this case in scripts.

The assignment operator (=) works incomprehensibly if a variable rather than a constant (number) is used as the array index.

For example:

//---------------------

double s[10] ;

int i = 0;

double priceOpen = 10;

while( i < 10)

{

s[i] = priceOpen; // DO NOT APPLY. If s[5] = piceOpen; then a VARIABLE of the array takes on a new value...

i++;

}


dear developers, moderators...

QUESTION I repeat! arrays are the key definition of any programming language.

What is the point of objects if the BASIC principles are not well documented!

For clarity, try looking at GetLastError() after the assignment operator - it should help with the breakdown. At least, everything works fine in this example. ;)
 
Question. Is there an option somewhere in MT4 that when I close MT4 I get a warning message like "do I really want to close the program, yes/no". I closed MT4 a few times by mistake and had to reconfigure EAs.
 

paladin80:
1. Вопрос. Есть ли где-нибудь в МТ4 опция чтобы при закрытии МТ4 появлялось бы окошко с предупреждением типа "действительно ли я хочу закрыть программу, да/нет".


2. A few times I accidentally clicked in the wrong place and closed MT4 and then had to reconfigure the EAs.


1. No.

2. Save the "Profile" regularly.

2. Save the "Profile" regularly.

So, just to confirm - does the "Profile" remember all individual settings for all EAs for all currency pairs?

"So, just to confirm..." - go ahead and confirm it yourself.
