Historical data export to csv

Hi,

I need a script which will let me export all available symbols to one file. I want to work with exported data in Excel.

I should be able to choose time interval (e.g. 5 min, or 15 min, or 1hr, or 4hr, or 1day, or 1 week), price (open, or high, or low, or close).

It would be nice to be able to specify time frame of export.

Every single line of export, for each time stamp, should look like:

date (e.g. dd.mm.yy); time; price1; price2; price3; ....; price n;

First line should be a header with symbols.

If price does not exists in MT database then there should be no value ;;

Decimal places should be comma separated "," 

Script should export data to MQL4/file folder with fixed string and name of the broker and current date.

Kind regards
