I download the PR.zip file from NSE "market today" link everyday after 5pm usually.There is a Pd* excel file there on which I run a excel macro.Macro converts it to csv file which Downloader can convert to Metastock format.
I agree it a little manual process but you wont have to depend on anyone.Whenever NSE makes the data available, you get EOD Metastock data updated in 2-3 mins.Ohh I forgot to tell you my laptop is a celeron one.You guys must be having good configuration.If you need the macro,give me a mail to kdatta33@ yahoo.com
