Realtime Data is alone sufficient to describe that the data should be real and live at the user end.The share market has covered a wide area in the economy of a country.This promotes people to get into share market.A large no of softwares are available in the market to monitor the share prices of the stocks.This makes a demand of cheap as well as reliable softwares for the investors.Softwares basically shows the live tick by tick price variations of the stocks.The reason for choosing a software mainly matters on its co-ordination with live market,scrip list,its reliability,etc.

It consists of NSE-Equity cash,NSE-Equity Futures and options.It was started by a clutch of leading Indian financial institutions.

                                   2.National Stock Exchange(NSE)

The National Stock Exchange of India Ltd. (NSE)  is a stock exchange located in the financial capital of Mumbai, India. National Stock Exchange (NSE) was established in the mid 1990s as a demutualised electronic exchange. NSE provides a modern, fully automated screen-based trading system, with over two lakh trading terminals, through which investors in every nook and corner of India can trade.

NSE and the Bombay Stock Exchange are the two most significant stock exchanges in India,

and between them are responsible for the vast majority of share transactions. NSE's flagship index, the S&P CNX Nifty, is used extensively by investors in India and around the world to take exposure to the Indian equities market.

NSE was started by a clutch of leading Indian financial institutions. It offers trading, clearing and settlement services in equity, debt and equity derivatives.The Exchange has brought about unparalleled transparency, speed & efficiency, safety and market integrity. It has set up facilities that serve as a model for the securities industry in terms of systems, practices and procedures. 

     3.How NSE brought a shift in Financial Market

 

NSE was mainly set up to bring in transparency in the markets. Instead of trading membership being confined to a group of brokers, NSE ensured that anyone who was qualified, experienced and met minimum financial requirements was allowed to trade. In this context, NSE was ahead of its times when it separated ownership and management in the exchange under SEBI's supervision. The price information which could earlier be accessed only by a handful of people could now be seen by a client in a remote location with the same ease. The paper-based settlement was replaced by electronic depository-based accounts and settlement of trades was always done on time. One of the most critical changes was that a robust risk management system was set in place, so that settlement guarantees could protect investors against broker defaults.

NSE was also instrumental in creating the National Securities Depository Limited (NSDL) which allowed investors to securely hold and transfer their shares and bonds electronically. It also allowed investors to hold and trade in as few as one share or bond. This not only made holding financial instruments convenient, but more importantly eliminated the need for paper certificates and greatly reduced the incidents of forged or fake certificates and fraudulent transactions that had plagued the Indian stock market. The NSDL's security, combined with the transparency, lower transaction prices and efficiency that NSE offered, greatly increased the attractiveness of the Indian stock market to domestic and international investors.

                                                4. Realtime Data types

NSE stock data can be broadly classified in the following two categories:

Realtime Data: 
Real-time data from NSE refers to programmatic real-time auctions that sells impressions. Entities on both the buying and selling sides of equity shares require almost instantaneous access to data in order to make decisions, forcing real-time data to the forefront of their needs. It is the most important and live data from the exchange.It regulates the price of the stocks available in the market.

  5.Features of Realtime Data

While looking for realtime data of various stocks,these following things comes first in prioity:

Accuracy: The realtime data which is shown should coincide with the live market price of the  stocks.Thereby,the live tick by tick update should be accurate with the market movement.Data must be accurate and should fastly update with market price.

Data Integrity: The software must be capable enough to recover as soon as possible,in case of any technical problem.Like if there comes a gap up in the formation of candlesticks,then it should be able to succesfully update it.

Affordable price: The data should be available at an affordable price.This will probably increase the availability of the software to a large number of people.

User Friendly: The software should have proper indications so as to make it accesible at an ease.

Transparency: The authenticity of the data is discussed here.The data should be true to its viewer.

Simultaneous updations of multiple scripts: Might be unbelievable but RTDS have made this revolutionary technology possible. Stock Traders and analysts are very busy during trading hours. It is very tough for them to separately select and update scripts. With the softwares like these are no problem because everything is automatic, both backfilling and real time update all are simultaneous.

                                       6.Sources of Realtime Data

The Data providers source their data broadly from three popular sources - 

i)Websites (Yahoo Finance,Google finance,etc.)

Applications falling under this category are installed on client's computer and they keep querying website servers for data. The application providers do not have to invest any money in installing and maintaining the data servers, leased lines, etc. because the data is already available on websites and internet line of the client is used to fetch the data. Hence data vendors who provide data from websites like yahoo finance can offer their product at cheapest price.

ii)Trading platforms (Odin, Chartnexus, Investar,etc.)

Here too, the case is more or less similar. The only difference is - instead of Yahoo or other sites, these application providers extract the data from the trading platforms provided by the broker. Again - since data vendors do not have to maintain any data servers, dedicated leased line connections, etc., their products are available at cheaper prices.

iii)Direct from Exchange

The case is entirely different here. These data vendors like Rtdsdata source their data directly from the stock exchange i.e. through a legal channel. The application providers falling in this category make significant investment in installing their data servers in worldclass environment, leased line connections, redundant server connections to take care of any failures, skilled manpower to install and maintain the setup, etc.. They also need to pay fixed yearly license fees (ranging in several lakhs of rupees) alongwith per user charges to stock exchange. For these reasons, the price of their products is comparatively higher than other 2 types of providers.

      8.Authenticity of Realtime Data 

The realtime data should be true to the receiver.The authentic data always comes in priority. There are various sources to verify the authenticity of the data.Like if someone is viewing the updates in any random software ,and at the same time he wish to verify that whether the data shown is correct or not,then he can recommend the official sites of the exchange like www.nseindia.com.for national stock exchange in india.

As the data comes from the exchange to the software through various servers in between,hence the authenticity and the respond time of the updation process is a must check criteria. 

       9.Pros and Cons of Cheap Realtime Data

->When any application is available as free, the providers are not obliged to provide any additional features. Timely updates and bug fixing alongwith continuous application development may be significantly hampered.

->If you miss any ticks because of internet connection problems or for any other reasons, you won't know about it till the time the market gets over / the data is backfilled by the data vendor.

->The source of cheap market data is either websites like Yahoo Finance or Trading Platforms like Odin. Any change in website underlying structure, new application version can suddenly stop the data flow - without any notice and it can take from days to month to bring a fix. 

->Limited no. of symbols are usually available.

->Ambiguos Realtime quotes,the realtime quotes are generally delayed.Most prices of securities that are displayed on various websites are delayed quotes. These quotes are usually delayed from 15 to 20 minutes. Real-time quotes are instantaneous with no delay. 

->Applications which featch data from websites are pull type applications. Several queries are sent to websites to fetch the data - resulting in higher bandwidth and CPU usage.
