Well guys, i have used at least 3-4 data providers and here is my feedback for them,
1) Reuters QuoteCenter - Well, as the name suggests, the quality and accuracy of data provided is outstanding. Also, you get a subscription of their TA package, custom indicators and organised world/local finance related news. However, the cost is approx Rs 8,000 per month. Just too expensive.
2) Esignal (U.S.) - This is at par with what Reuters provide. The service, quality and accuracy of data is impeccable. Not even once i found any error in data provided by these guys. Data can be easily imported into metastock and can be used suitably. However, like Quaote Center the cost is about Rs 4800 a month.
3) Trend Watch India (TWHD) - This service is provided by Mr. Deepak Mohoni's Trend Watch India. The service is good and the accuracy of the data is good. However sometimes, in some quotes, some information is corrupted. This causes the entire stock's price history to be displayed in an incorrect way. Customer service and any other queries are handled exceptionally well. Price is approx Rs 5000 a year.
4) Market Data Provider - This is one service which I think comes close to Reuters and Esignal. The data is amazingly accurate and the service is excellent. I would rate this above the rest on two aspects. First, the UI is friendly and the software is very well documented. Second, the price at which they provide data is certainly very affordable (Rs 2999 for EOD NSE, BSE, FNO). Personally I prefer this.
5) Free Softwares (Bhavcopy, NSE/BSE data downloader etc) - These softwares are free of charge and do their job well. However, sometimes I do find some irregularity in the data. The data is claimed to be downloaded from NSE, but still in some places important information like volumes, price etc goes missing. These softwares are no doubt the best tool available for those who do not want to spend even a single penny for data acquisition. Kudos to the makers. :thumb:
