QuantConnect - Performance and Accuracy
Performance
QuantConnect’s performance can be influenced by several aspects of your algorithm and the platform’s capabilities:Data Resolution
Using high-resolution data, such as tick or second data, can significantly slow down your algorithm due to the large number of data points to process each day. It is recommended to use such high-resolution data only when necessary.Language and Interactions
While QuantConnect supports both C# and Python, C# is generally faster, especially in backtesting scenarios where it can be 2-3 times faster than Python. However, this difference is less noticeable in live trading due to the dominant execution time of brokers like Interactive Brokers.Algorithm Complexity
Complex calculations, particularly in the universe selection function, can slow down your algorithm. Simplifying these calculations or reducing the frequency of complex operations can help improve performance.Data Access and Hardware
Accessing large amounts of data can slow down your algorithm, especially on shared hardware. If you’re using a free account, the shared hardware might not handle large data loads efficiently.Accuracy
QuantConnect is designed to ensure accurate backtesting and live trading through several features:Real-Time Data Streaming
The platform streams data in real-time for live trading, which helps in making accurate trading decisions. However, this real-time streaming can sometimes slow down the algorithm if it involves processing a large amount of data.Backtesting Capabilities
QuantConnect allows for point-in-time, fee, slippage, and spread-adjusted backtesting, which helps in simulating real trading conditions accurately. This feature is supported by thousands of unit and regression tests and handles multi-asset backtesting with realistic margin modeling.Alternative Data Integration
The platform supports the integration of alternative data linked to underlying securities, which can enhance the accuracy of your strategies by providing more comprehensive data sets.Limitations
There are several limitations to consider when using QuantConnect:Universe Filtering
There is a 5000 stock limit on universe filtering, which could be an obstacle if you need to filter a larger number of stocks.Hardware and Resource Constraints
Free accounts may face performance issues due to shared hardware, which can limit the amount of data and complexity of algorithms you can handle.Learning Curve
QuantConnect has a flexible but sometimes steep learning curve due to its extensive capabilities and event-driven backtester. Getting acquainted with the API and how data flows through the system can take time.Areas for Improvement
To optimize performance and accuracy on QuantConnect, consider the following:Optimize Algorithm Complexity
Simplify complex calculations and reduce the frequency of data access to improve performance.Use Efficient Data Resolution
Use lower data resolutions unless high-resolution data is necessary.Leverage C# for Backtesting
Use C# for backtesting to take advantage of its faster execution speed compared to Python.Monitor and Adjust Resource Usage
Be mindful of the hardware limitations, especially on free accounts, and adjust your algorithm accordingly. By understanding these factors and optimizing your approach, you can maximize the performance and accuracy of your algorithms on the QuantConnect platform. If you encounter specific performance issues, sharing your algorithm with the QuantConnect support team can help identify and resolve the root causes of the slowness.

QuantConnect - Frequently Asked Questions
Frequently Asked Questions About QuantConnect
Can I Use QuantConnect’s Data Feed and Make Trades from My Local PC with a Prime Subscription?
If you subscribe to the Prime service on QuantConnect, you cannot utilize the subscription data feed and make trades directly from your local PC due to licensing restrictions. Local backtests can only use local data or data you have purchased and added to your QuantConnect data library.
Can I Make External REST API Calls from the Hosted QuantConnect Service?
Yes, you can make external REST API calls from the hosted QuantConnect service, both during backtesting and live trading. This functionality is supported, allowing you to interact with external servers, such as an AWS hosted server, as needed.
How Does QuantConnect Handle Data Caching for Backtests?
When backtesting with QuantConnect on your local PC using your own data provider, the data is typically loaded from the provider each time you run a backtest. However, you can implement caching mechanisms to speed up subsequent backtests. QuantConnect does not automatically cache data for you, so you would need to set up your own caching solution.
Does QuantConnect Leverage Distributed Processing for Backtests?
QuantConnect’s backtests generally run on a single machine, although the platform is cloud-based. However, for optimization tasks, QuantConnect can leverage multiple machines to speed up the process. This distributed processing is particularly useful for parameter sensitivity testing and other computationally intensive tasks.
Can I Write and Debug Algorithms in Python Using Visual Studio or LEAN?
Yes, you can write and debug algorithms in Python using the QuantConnect.Python project in LEAN. This allows you to use Python within the QuantConnect environment, providing flexibility in your development process.
What Are the Dependencies for Live Trading on Desktop (LEAN)?
For live trading on your desktop using LEAN, you need broker-specific credentials (e.g., Interactive Brokers account, username, and password). However, if you want to use local charting features, you may also need to use the API access token and job-user-id provided by QuantConnect.
What Are the Pricing Plans for QuantConnect?
QuantConnect offers several pricing plans:
- Researcher: $10 per user/month, suitable for individuals starting with quant finance.
- Team: Starting at $24 per user/month, designed for team growth.
