I am looking for reliable data vendor supplying EOD data adjusted for splits, bonus etc.
Who is the best vendor for it? I've found two folks who supply such data for NSE...
1. istocksystems.com (Core Trade) which costs ~Rs 3600
2. viratechindia.com/stocksup_eod.html which costs Rs 9000 + service tax.

Can anyone suggest which one to go for? Whose service will be more reliable and trustworthy?
