Tutorial on Python Algorithmic Trading with the FXCM Broker

Incorporating technological solutions has become a crucial strategic move for businesses and financial institutions, and for good reason. Among the plethora of tools available, Python has emerged as one of the most widely-used programming languages in the finance industry. The predictive and forecasting abilities of algorithmic trading techniques implemented using Python have sparked a revolution in the field of financial technology, with the technology’s profit generation potential being increasingly recognised.

In this post, we will illustrate how algorithmic trading can be executed using the Python programming language and the FXCM broker platform.

Which components are included in trading algorithms?

Algorithmic trading, also known as quantitative trading, employs mathematical and statistical models to analyse financial markets. This particular domain of the financial technology sector is known for its complexity and difficulty.

With Python’s algorithmic trading framework, investors can automate their trades through computer programs. This technology also facilitates the tracking of market fluctuations, providing investors with the necessary information for making informed investment decisions.

Upon meeting the algorithm-defined criteria, a buy or sell order is executed automatically. This method enables quick market analysis and trade execution through automation.

Different Types of Algorithmic Trading Techniques

To leverage the full potential of algorithmic trading, identifying profitable opportunities that can be exploited is crucial. Among the various strategies that can be employed, quantitative trading techniques such as trend following, mean reversion, arbitrage, and high-frequency trading are some examples. Each strategy has its own benefits, and selecting the optimal approach will depend on several factors such as market conditions and an investor’s objectives.

  1. Trend-based Techniques

    Among the algorithmic trading techniques, the most widespread approach is to detect and leverage market trends. Traders focus on observing chart patterns such as moving averages, channel breakouts, and price level fluctuations along with other relevant technical indicators to identify and track market trends. Since these trends can be automated more readily, traders seldom need to rely on price forecasts or predictions. Typically, the time frame for trend monitoring ranges from 50 to 200 days.
  2. Arbitrage Opportunities

    Arbitrage, the process of exploiting price discrepancies in securities listed on two different exchanges, offers investors a means to generate profits. By purchasing stock at a lower price on one exchange and selling it at a higher price on the other, investors can take advantage of the price difference. To capitalise on this possibility, algorithms can be employed to identify lucrative openings.
  3. Adjusting Index Fund Weightings

    Algorithmic trading through index fund rebalancing has gained widespread momentum. This approach entails aligning an index fund’s holdings with its benchmark index, resulting in a typical profit of between 30 and 80 basis points. The rebalancing timing depends on the number of stocks held within the index fund.
  4. Mathematical Applications

    The delta-neutral trading technique enables options and securities trading. This strategy involves balancing positive and negative ratios against each other and considers the relative price changes of assets.
  5. Mean Reversion

    The mean reversion strategy is based on an asset’s high and low prices. Traders can automate trades when an asset’s price experiences substantial fluctuations beyond a predetermined range. To accomplish this, they must determine and define the appropriate range through an algorithm.
  6. Volume Weighted Average Price (VWAP)

    The VWAP strategy facilitates the division of substantial orders into smaller components, which are then traded in the market at real-time prices based on an asset’s historical volume characteristics. Following this approach, investors can anticipate their orders being filled at or near the asset’s volume weighted average price.
  7. Time Weighted Average Pricing (TWAP)

    TWAP is a pricing mechanism that enables the division of large orders into smaller, manageable portions by assigning them to various timeframes during the trading session, from start to finish. This method automatically executes the order at an average price within the defined period, thereby reducing its impact on the market.
  8. Addressing Implementation Shortfalls

    Spot market trading aims to minimise the implementation shortfall of an order. An increase in the desired participation rate occurs when the stock price rises, while a decrease takes place when the stock price falls.

Role of the FXCM Broker

FXCM (Forex Capital Markets) is a well-known online platform for trading Contracts for Difference (CFDs), foreign exchange (forex), spread betting and similar services. FXCM offers access to CFDs on prominent indices and enables traders to engage in speculation within the foreign currency market via its online platform.

The FXCM broker provides traders with cutting-edge trading tools, superior trading instructors, and a premium online trading platform, allowing access to extensive markets. Their platform offers a real-time trading experience from any mobile device with just a few clicks.

FXCM Trading APIs

Application Programming Interfaces (APIs) allow for a secure and dependable data exchange protocol between programs, enabling the creation of useful and innovative applications. FXCM provides access to four free APIs, which can be found in our blog post on developers:

  • API-based on Representational State Transfer
  • Standardized FIX-based API
  • API for the Java Platform Interface
  • ForexConnect-based Programming Interface

Each of these APIs provides direct access to the FXCM trading server.

Using a RESTful API

The RESTful API provided by FXCM Brokerage is specifically designed for algorithmic trading, utilizing a web-based API that enables communication between a server and client via a WebSocket connection. Furthermore, the FXCM platform serves as a robust foundation for developing customized trading software that seamlessly integrates into the primary platform.

OAuth 2.0 is a secure authentication protocol that facilitates access to resources through token-based authentication. At FXCM, we utilize this protocol for added security to our applications and support the integration of hybrid programs, making authentication more seamless. Additionally, the protocol enables FXCM to stream JSON data through the socket.io library, providing real-time updates to users.

Financial Industry Xchange SDK

The FIX API is an industry-standard protocol that enables quick and secure transmission of market data, allowing for the exchange of financial information at the rate of up to 250 price changes per second. This protocol is widely implemented across the financial services industry.

API for Java Applications

Access to the FXCM trading platform is available through the Java API, a Software Development Kit that wraps the FIX API, offering a fully customizable and scalable API. This lightweight and versatile API can be utilized across any Operating System compatible with the Java language.

API for Forex Connect

The ForexConnect API offers an array of features to support efficient position management, such as live price streaming, order management, access to historical instrument rates, and the retrieval of account reports. These capabilities empower users to optimize the potential of their trading activities.
