The contemporary marketplace is an ultra-competitive atmosphere where being technologically savvy is a prerequisite for success. Trade is conducted on a near 24/7 basis by individuals around the globe via internet connectivity and software trading platform. The rise of exclusively digital markets has increased the need to eliminate any unnecessary latency.
In order to stay on the lead lap, a trader must strive to interact with the market as efficiently as possible. Integrating an Application Programming Interface (API) into a trading operations' infrastructure is a popular way of enhancing performance. An API with robust capabilities facilitates a streamlined flow of data from the market to the trader's base of operations and vice versa. In turn, undue latencies are reduced and numerous advantages are afforded to API traders.
As technologies in the financial markets have advanced, API trading has become available to the masses. Assorted varieties of specialty API products are available to retail and institutional participants alike. "FIX" API ranks near the top of the list, earning a reputation for being fast and user-friendly. Over time, it has become a forex industry standard.
FIX API Defined
The Financial Information Exchange (FIX) API is a set of clearly defined rules and methods designed specifically for the electronic transfer of financial data. In the nomenclature of the industry, it is "electronic communications protocol for real-time information exchange for financial securities transactions."
The FIX API fosters a seamless flow of real-time data between market participants. It is used by liquidity providers, traders (retail and institutional) and regulators to address the market on an ongoing basis. The primary function of FIX API is to facilitate the transfer of three distinct types of data:
- Pre-trade: Pre-trade information is used in crafting strategies and decisions for implementation on the market. This type of data includes levels of liquidity, order flow and depth-of-market statistics streaming directly from exchange or market servers.
- Trade: Trade-related information is focussed on the act of conducting trade. Order entry, confirmation and execution functions involve the transfer of data through FIX.
- Post-trade: Post-trade data aids in the recording, processing and transfer of asset ownership involved with market-based transactions.
While many APIs offer similar functionality in terms of data transfer, the FIX API furnishes users with several unique advantages that include the following:
- The FIX Protocol allows for a rapid transfer of vast quantities of information.
- FIX's standardised language and widespread acceptance ensure a quick and easy set up.
- Proprietary algorithmic or black-box strategies may be readily created.
- Implementing a FIX API preserves the anonymity and privacy of proprietary systems operating within the market.
In effect, the FIX API serves as a gateway to the marketplace. A broad spectrum of financial instruments are readily engaged including equities, futures, contract-for-difference (CFD) and forex products.
Background And History Of FIX API
The FIX Protocol was originally developed in 1992 by Robert Lamoureux and Chris Morstatt. The initial objective was to enable the electronic transfer of data pertaining to the equities markets. Upon becoming functional, it facilitated communications between brokerage firms Fidelity Investments and Salomon Brothers with their institutional clientele.
From the onset, FIX was designed to promote efficiency in trade-related communications. At the time, a vast majority of correspondence between traders and brokers was conducted verbally over the telephone. Upon the introduction of FIX, these dialogues became digital. The transition took much of the guesswork out of communications, as the once verbal exchanges became automated.
Championed by FIX Protocol Ltd, the standardised FIX Protocol language became a financial industry standard. Market participants found FIX to be valuable in terms of minimising trading costs and maximising communication efficiency.
In 2013, FIX Protocol Ltd became the FIX Trading Community and gained a significant membership base:
- Over 290 international financial services companies participate. Premier partners include Bank of America, Barclays, Bloomberg, Credit Suisse and the London Stock Exchange Group.
- FIX is a global network with members located on every continent.
- Members include brokerage firms, liquidity providers, regulators and trading venues.
The FIX Trading Community maintains a not-for-profit status with the primary goal of addressing industry needs and promoting efficiency. It is widely viewed as a major contributor to the development of modernised capital markets.
Benefits Of Using The FIX API
Institutional participants find the FIX Protocol to be a reliable way of staying connected with clients, member firms and the market in general. The applications of FIX are also beneficial to independent retail traders.
The main benefits of using FIX with FXCM are:
- Fast login and more stable connection.
- Industry standard trading protocol (not proprietary API).
- On every change in order status the FIX server sends updated Execution report.
- No price throttle that the Market Data session sends all BBO (best bid offer) prices we have, (all other API's limited to 3 prices per second per symbol).
- Additional FIX servers store FIX logs on server side, which is very helpful on client integration and order audit.
FIX APIs are compatible with a vast network of brokerages and supported software trading platforms. The FIX Protocol 4.4 is a popular tool for active traders, both retail and institutional. It features robust performance, and facilitates as many as 250 price updates per second.
In addition, FIX Protocol 4.4 integrates seamlessly with C++, C# and Java programming languages.
Since its inception in 1992, the FIX Protocol has contributed to the speed and efficiency of the digital marketplace. From streaming pricing data in real-time, to enhancing order execution, the FIX API can be a valuable tool for individuals interested in reducing trade-related latency.
