Table of Contents [ Hide ]. Read Review. Banks have also struggled with distinguishing data aggregators from hackers trying to conduct fraudulent behavior. Consumers can experience account lockouts in these instances if there have been too many failed attempts to log in, which hurts client relationships.

Some large banks had responded by banning data aggregators from accessing their websites. IP stands for internet protocol because it represents the format for which data is sent via the Internet. IP addresses identify a local address of a computer or a network so that information can be sent electronically between devices.

If a bank blocks an IP address, it prevents the data aggregator from retrieving the information. The consumer who is using the data aggregator, like Mint, would see an error message. The bank clients would get frustrated by the inability to interface with their bank using the financial app, which could lead to them switching banking providers. Also, many banks are using data aggregators to power their mobile platforms, making the situation more complicated.

Consumers have been caught in the middle of this struggle between their bank and financial applications. Without the cooperation of banks, the customer might see inaccurate data reported on their data aggregator or might not be able to access their financial data at all.

Data aggregators themselves might also cause their online banking experience to slow down or account lockouts. A solution for banks and aggregators that has surfaced is an application programming interface API designed to handle data requests. The data is also more reliable since it hasn't been scrapped in an archaic fashion. In , several banks partnered with data aggregators and fintech firms to establish an organization designed to create a governance framework for sharing data and privacy.

The Financial Data Exchange FDX was formed to protect customer data but allow financial aggregators and fintech companies to access the bank account information. The FDX is governed by a board of directors picked from financial institutions, fintechs, and data aggregators.

The FDX is a nonprofit organization in which all of the members pay dues to fund its operation. The FDX has been addressing financial data privacy concerns, including the practice of scraping by third parties. Instead of allowing scraping, consumers who use a financial aggregator are presented with a login screen for their bank, allowing them to choose what data to share with the financial app.

Although there will undoubtedly be issues that arise in the future with securing consumers' financial data, the FDX is a positive step in the right direction. Through cooperation between banks, fintech firms, and financial aggregators, the FDX can help prevent consumers from being impacted by technological glitches while also preventing hacks by outsiders and fraud.

The downside is the refresh rate is not so good, and the data is derived from BATS only. Yahoo also has an API that can be tapped into although it is rate limited and will IP block you if you make too many requests on it in rapid succession.

Google Finance - Like Yahoo, Google is good geographic research most international exchanges , but our feeling is that Google doesn't take Google Finance very seriously, so errors are more common, and like with Yahoo, some key futures exchanges and less common instruments are missing, however, it does provide better charting capabilities.

Professional feeds will aggregate data from all markets including regional exchanges to build a consolidated book. Instead of querying an API at pre-defined intervals, professional feeds pass all data to the client as it is sent out by the originating exchanges. These solutions are generally high bandwidth, high update frequency, and lowest latency. QuantQuote TickView — TickView by QuantQuote is a very solid product that is available in both an exchange colocation environment and also via the internet.

TickView automatically performs feed consolidation TickView consolidates data from over a dozen exchanges. The application is natively Linux and for non-colocated clients, utilizes an advanced compression to save bandwidth.

Pricing tends to be higher than TickView for a similar amount of bandwidth usage. Latency found to be slightly higher than TickView. Can send you data from all exchanges separately not NBBO consolidated but requires lots of bandwidth and pricey dedicated fiber lines. For the fiber connection, Thomson Reuters partners with Savvis to provide connectivity.

Overall, a good service, but QuantQuote and Nanex provide more cost effective alternatives. Non-professional feeds do not give a true indication sense of market activity as they generally redistribute data from only one or two exchanges, such as BATS or the NYSE consolidated tape.

Furthermore, the data they send out is usually snapshots with larger update intervals and longer latency. Clients generally query the data via an API on request, instead of having every tick sent. As our focus is programmatic trading, we did not review any of the vendors listed below, they are just included for completeness.

We welcome feedback from members and alums about these services. The consensus that we have is that solutions such as QuantQuote TickView are not that much more expensive compared to the non-professional solutions listed here and we recommend using a professional feed for optimal quantitative trading results.

Beyond the scope of this article, but many exchanges allow customers to be collocated on site and access data feeds directly without going through 3rd party market data vendors.

For port access, connectivity, and rack space, the minimum charges for these types of services can run tens of thousands per month, per exchange.
