I use MLDownloader since 2006 and it was until 2017 a good source for EOD Quote data. I use it for German, European, US, Australian and Asian markets, Indices and stock quotes.
I used it until April 2017 at a 13y old Sony Vaio Win XP home laptop and since April 2017 at a newer Sony Vaio Win 10 home laptop - i was happy that it works fine with Win 10 at a very fast download speed.
It happens, that it didn't work for some days which seems maintanance reasons because the distributors Website was also down these days.
But since 01 November 2017 nothing works and the last quotes i get at 01 November 2017 have been for Australia, Japan and China.
The error message is 'Yahoo Proxy Server Problem. Please download the data again.'
Switching source to 'Google Finance' changes nothing and no quotes are downloaded in any way.
I hope that MLDownloader will work from one day to the other, because it is distributed at the Website www.trading-tools.com
and is not discontinued. It would be fine if someone know more about this, thx.
ML downloader is now virtually useless. They haven't updated the software to cope with the API changes at Yahoo (Amibroker have done so but even they still have a few glitches to sort out as far as I know). Can only assume that Yahoo don't want lots of people downloading loads of data at once. It is still possible to download historic data for individual tickers at Yahoo – into CSV file which can easily be manipulated for upload. Yahoo data is still useful if you have unsophisticated needs and don't mind lots of balls-aching manipulation and cleaning up of data. You are probably best buying the data elsewhere and using time saved to more than earn back the cost.
It is extremely unsatisfactory that the publishers of ML downloader still continue to sell it.
