Can I unload data from the terminal for processing in Excel?

Via ... ...you can. You got it wrong, through IE you can. Save the report open it in IE and convert it to Excell from there

I did it only once, so if something is wrong, do not hurt, maybe not remember something wrong.

There are scripts for this, you can use F2 - export.
 
Thank you!)

I want to write an Expert Advisor on the "Supertrend" indicator.

But it is not built into MT4 and I don't know how to get data from the indicator.

May you help me with advice?

Here is the code of indicator "Supertrend".

Data from the custom indicator is obtained using the iCustom function

I am just getting started with MQL4, I cannot figure out iCustom.

Could someone please help me to extract this data from the "Supertrend" indicator code above , so I can apply it to an Expert Advisor?

Well, you'll have to do it, what else could it be? If you want to write an Expert Advisor...

The Help has an example, do it like this: iCustom(symbol, timeframe, "Supertrend", you don't have special parameters, so let's skip this position, set the line number and the number of bar you need)

 

In the meta-iditor there is a prompt function, type the operator and press F1.it says everything you need to input the operator. it is done like this:

double UP=iCustom(Symbol(),NULL,"Supertrend",0,0);

double DOWN=iCustom(Symbol(),NULL,"Supertrend",1,0);
