Scripts: Export Indicator's Values v1 - page 2

Doesn't work.
 
I can't export values from the 50 period Exponential Moving Average, could someone help me?
 

Search for the file in the folder

The script is very nice, but I would like more if the data could go to excel directly, via a RTD server, to use excel's RDTR function. Do you have something like that planned?

Yes it works. You need to look at ...MQL5\Files path, its there the CSV file.

I´ve modified to save values of OBV (real volume) just change the code below 


Indicator_Directory_And_Name="Examples\\OBV";
IndicatorPeriod=VOLUME_REAL;

Hi,

Thank you for the job.  Unfortunately, when I run the script, no file is created. I updated the script to write in C:/temp/. When i run in debug I can see that the filename is correct and I don't get any error but there is no file.

Any clue ?

 

 


If you check the handle, it will probably is returning -1. (invalid handle)


Print ( "fileHandle Value=", fileHandle);


For some reason MT5 doesnt´like that you save files in different places from default. Just let as original code and it will write in ...MQL5\Files path 

 

Congratulations on the script, I am exporting the values of the volatilitypivot flag to csv, but the script only correctly exports the high values, in the lines that should appear the low values an error appears.

Can someone help me please ?
