Global Datafeeds – NSE,BSE & MCX Authorized Data Vendor

Intraday trading is a trend in India nowadays, so many beginners want to earn profit from Indian markets like NSE, BSE, MCX, CDS, etc. But becoming a professional trader is a journey. Managing your trading budget with proper stop-loss and target helps to grow your portfolio. This journey requires sufficient knowledge of trading, budget, and market data during trading hours and after the market ends. This data can be accessed for real-time trading in two ways: as

1) NSE, BSE & MCX Authorized Data Vendor

2) Third-party data providers

In the following blog, we will consider the NSE data vendor mostly because it is the trusted source of obtaining market data. We won’t look at any third-party data providers since they can be risky, which may cause issues such as lagging data and inaccurate data, and some of them might be scammers who may cause serious concerns by hacking your personal information, such as login details, bank details, etc.

While choosing the NSE stock market data provider or NSE f&o data provider, you must be aware of them.

Now, we will focus on the type of data needed during market hours and the data observed after the market closes, considering the data provided by an authorized data provider or vendor.

Who is a Data Vendor or Data Provider?

A data vendor is a company that is authorized and trusted by financial exchanges, such as NSE, BSE, and MCX, to deliver real-time or live market data feeds to traders. These vendors hold legal rights from the exchanges to access market data directly from the exchange servers, typically via secure connections like leased lines. The raw data is then processed and formatted to make it suitable for trading platforms in the form of real-time data, ensuring day traders receive accurate and timely information for their decision-making.

GFDL has served for more than 13+ years as the most trusted data vendor of NSE, NFO, BSE, BFO, MCX, and CDS for the seamless delivery of real-time, live, and tick data.

Let’s explore the type of Data and APIs provided by GFDL!

What is Real-time Data & Who is an Authorized NSE Realtime Data Provider?

What is NFO Backadjusted Data? Who is an authorized NFO Backadjusted Data Provider in India?

• Futures contracts are popular among traders today, but they can be tricky because each contract has a different price depending on its expiration date, and contracts expire monthly. This makes analysis difficult, as different prices for various expiration dates can be confusing.
• To solve this, traders use a process called splicing to combine data from multiple contracts into a continuous series.
• Spliced contracts help create a smooth price series by connecting consecutive contracts, allowing traders to analyze long-term trends. This typically involves rolling from one contract to the next at specific points, such as when the nearest contract is about to expire. The result is a continuous dataset that shows price movement over time without the gaps caused by contract expiration.
• When someone wants to hold a futures contract longer, they need to sell the current one and buy the next one, but the price difference between contracts can create jumps or gaps in the data that aren’t real profits or losses.
• To handle this, traders rely on NFO backadjusted data, which smooths out these price differences and removes the artificial gaps caused by switching between contracts. This ensures the data is more accurate, allowing traders to analyze their strategies without being misled by false gains or losses.
• GFDL is an authorized provider of NFO backadjusted data for every NFO contract in India.
• GFDL is also authorized nifty bank nifty futures data provider for the last 12+ years.

What factors do a trader consider when selecting an NSE Authorized Data Vendor?

The NSE is ranked among the world’s top 12 exchanges by total market capitalization. Hence, it is again an important responsibility of NSE and other exchanges to authenticate and certify the data vendors to maintain trust and authority in the financial markets. Hence, an NSE-authorized data vendor must meet the legal requirements instructed by NSE and other exchanges, and a data vendor must follow SEBI.

Every Data Provider should complete the following criteria per the exchange norms before providing traders with real-time or live data feeds.

1) Data Provider Must Ensure Fast Data Delivery with High Uptime

Be careful to choose the NSE Data Provider as he must deliver the real-time data using high-speed servers, which provide data in practical uptime, possibly 99.99%, to ensure the data availability without interruptions.

2) Zero Downtime During Market Hours:

During live market hours, server failures or issues are common. During live market hours, any update on the server side may cause delays in delivering data to traders, commonly called “downtime.” Even a short lag in downtime can cause a significant financial loss in fast-moving markets. NSE Data provider should provide market data with zero downtime.

3) Real-Time Data Feeds given by Authorized NSE Data Vendor

An essential function of an authorized NSE data provider is delivering real-time market data feeds with almost no delay, which helps a trader make fast trading decisions based on the most current information available in the market.

4) Cross-platform data Integration provided by the NSE Data Vendor

In today’s trading environment, users often switch between multiple devices and platforms, such as desktop software or web browsers, and use Cloud-based platforms, APIs, etc. A good authorized NSE data provider ensures that the market data is easily accessible and seamlessly integrated across all these platforms.

5) Security and Data Protection should be given from the NSE Data Vendor

As real-time or live data is sensitive, especially in financial markets, a data provider must implement encrypted protocols and advanced safety features to protect user information from cyberattacks or breaches. Data protection should be the prime important function a data vendor should have. NSE Data vendor must ensure the traders’ data is encrypted and stored securely across the platform.

6) API Access for Symbol Data from Indian Exchanges

The NSE Data Provider should offer API access that allows users to retrieve data related to NSE stock symbols, indices, futures, and commodities. This API enables users to access and interact with specific financial instruments (= symbols). Users should be able to integrate the real-time data with charting platforms for analysis easily.

7) API Integration & Leading Charting Platforms by NSE Data Vendor

The API provided by the NSE Data Provider should integrate real-time data with popular and up-to-date charting platforms. Thus, APIs allow traders to seamlessly connect their trading data with these platforms, which helps them create, customize, and run different trading strategies based on real-time market data as needed.

8) Detailed Real-Time API Documentation & Support

When traders request real-time data through the API, various issues might arise, such as IP address restrictions, exceeding the limit of allowed instruments, bandwidth limitations, or missing API keys. To effectively address these challenges, the NSE Data Provider must offer detailed API documentation and a robust support system.

9) Low-Latency Real-Time Data by NSE Data Vendor

During trading hours, the real-time data provided must have minimal latency. This means the data should be updated instantly, with no delays, ensuring traders have the most current market information every second.

10) Subscription of Realtime Data Should Be Affordable by NSE Data Provider

For professional traders, accessing real-time data should not be overly expensive, as traders already manage risks, profits, and losses. If the data is too costly, it adds an extra financial burden, reducing profitability. Therefore, the real-time data provided by the NSE Data Vendor must be affordable, ensuring traders can access it regularly without increasing their overall trading costs.
