This from the MT docs:

The previous versions of MT exported the available bars only without an error.

Many programs prefer delimiting the columns with tabs or semicolons because the comma is a decimal delimiter in several cultures.

I'm trying the Export Data to CSV script, and it is saving data to the MT 'Files' folder like this:

2016.10.21;03:50;127.466;127.468;127.45;127.455;44
2016.10.21;03:51;127.456;127.458;127.448;127.455;31
2016.10.21;03:52;127.455;127.456;127.446;127.447;13

It looks like there should be a "," where there is a ";"

This means it is not saving as a CSV file, no?

it is the same data as in the program.....

problem solved.

You can easily expand the number of exported bars be editing the script. Currently the script exports maximum 100000 bars.

You can change line number 30 to allow the export of more bars.

   int maxBars= MathMin(TerminalInfoInteger(TERMINAL_MAXBARS),100000);

Is there a way I can also change FSB Demo data to increase the maximum bar beyond 100,000?  So that with each new History Download, I can keep expanding the historical period and not such with the current 3mth period?

I tried to make the changes in FSB's user's file/system/FSB Demo data and increase default from 100,000 to 1,000,000 would this allow FSB to keep adding new historical data, expanding the period?  When I tried to download History Data, I see noticed the 100,000 default for 1min chart.  Did I miss anything?  Or this isn't the way to do it?

I found your post regarding data source period – that downloading new data overwrites the old data. The script used to download data from MT4 instance on your computer can be adjusted to enable larger data set to be downloaded, by editing line 30 in the script. But the problem which I have encountered (and probably others also) is that my Forex broker will not allow me to scroll back more than a limited amount of bars. For M1 it will be around 2 months of data bars.

And I prefer to have my broker’s data bars to be used in FSB Pro strategy developments. In that way I am more sure that results achieved with FSB and then on demo/live account (with my broker) will be similar.

BTW, I am downloading data bars from Live Account and not from Demo Account, even if I have confirmed that both have exactly same values during the feed process.

My solution to enlarging the data set is to regularly (once a week) download data from MT4 instance and copy it to a separate directory. Then I will use Excel to “glue” additional bars from newly downloaded CSV file to the old downloaded file. It is a lite primitive solution, but it functions perfectly. It takes only few minutes.

open MT4

click on files
click on 'open data folder'
click on MQL4

and you will see 'files'

Please, please. spend some time learning about MT4, use the internet and do some research.

Please do some reading about automated trading so that you grasp some understanding of the tasks ahead

Please get to know about FSBPro

This is a serious business and most people try to equip themselves properly so that they are not depending on others.

i have gone to data folder and to mql4 and ....files  which when opened is empty

Then go to to Data Sources of FSB> Create a source and give as directory there the directory where previous directory with created CSV data is.
The procedure is easy.

you will know that i am computer illiterate by now......sorry
