Algorithmic trading, often referred to as algo trading, is the use of computer algorithms to automate trading decisions and execute trades in financial markets. Algorithmic trading is widely used by institutional investors, hedge funds, and proprietary trading firms to enhance trading performance and efficiency. There are many private or individual investors who also do algorithmic trading. And of course, it is possible – yet convenient – to do it with Microsoft Fabric. Let’s explore how to do this.
Ingest Real-Time Data Into Fabric
- Direct Integration: Microsoft Fabric is designed to work with various data sources. You’ll likely need to find a market data provider (like Bloomberg, Refinitiv, or IEX Cloud) that offers an API or data stream compatible with Fabric. This might involve using connectors within Azure Data Factory (which is part of Fabric) to ingest the data.
- Real-time Ingestion: For true algorithmic trading, you need low-latency data. Look for providers that offer streaming data feeds. You might need to use Azure Stream Analytics within Fabric to process this high-volume data efficiently.
For example, Azure Stream Analytics can ingest data from various sources, including real-time APIs. You can connect it to Azure Event Hubs, IoT Hubs, or directly to a REST API. Here’s a basic outline:
- Create a Stream Analytics Job: Navigate to the Azure portal. Select Create a Resource > Analytics > Stream Analytics job. Configure the job with your desired settings.
- Define Inputs: Go to your Stream Analytics job. Under Job topology and select Inputs. Add a new input and choose the source type (e.g., Event Hub, IoT Hub, or Blob Storage)
- Connect to Real-Time API: If using Event Hubs, you can set up an Event Hub to receive data from your real-time API. Use the Event Hub connection string to configure the input in your Stream Analytics job.
- Write Queries: Use Stream Analytics Query Language (SAQL) to process the data. Here’s an example query to filter and aggregate data:
- Define Outputs: Configure outputs to destinations like Azure SQL Database, Blob Storage, or Power BI for visualization
Advanced Analytics with Market Data
- Data Storage: Fabric’s OneLake provides a centralized data lake. You can store your historical market data here for analysis and backtesting.
- Tools: Fabric offers tools like Synapse Spark for data processing and analysis. You can use languages like Python or SQL to develop your analytical models.
- Model Development: This is where you’ll build your trading strategies. You might use statistical models, machine learning, or time series analysis to identify patterns and predict price movements.

Implementing Algo Trading Strategies
- Logic: Translate your analytical models into specific trading rules. This involves defining entry and exit points, risk management parameters, and order types.
- Coding: Use a language like Python to code your trading logic. You might leverage libraries like pandas for data manipulation and scikit-learn for machine learning.
- Backtesting: Rigorously test your strategies on historical data to evaluate their performance and identify potential weaknesses.
Executing Trades
- Brokerage Integration: You’ll need to connect Fabric to a brokerage platform that allows automated trading. This often involves using an API provided by the broker.
- Order Management: Implement code to generate and send orders to the brokerage. This includes handling order types (market, limit, etc.), order sizes, and error handling.
- Monitoring: Continuously monitor your trading system for performance, errors, and unexpected market conditions.
Benefits of Microsoft Fabric for Algorithmic Trading
Having real time processing within the same set of tools where analysis is performed is a great thing. The user interface of Azure Stream Analytics and Kusto Query Language (KQL) allows anybody to work with real-time data. This is crucial for algorithmic trading, where timely data analysis and decision-making are essential.
My favorite benefit is security and compliance, as Microsoft Fabric is built on a secure and compliant platform, ensuring that your data is protected and meets regulatory requirements. By consolidating multiple data services into one platform, Microsoft Fabric can reduce costs associated with managing separate tools and services. This can lead to significant cost savings over time.
