Replacing a Charting Solution in a Trading Platform: A Comprehensive Guide
In the fast-paced world of trading, the accessibility, usability, and accuracy of charting tools can make or break investment decisions. Therefore, these tools’ underlying technology and functionality should be agile, robust, and efficient.
But what happens when your existing charting library fails to meet the standards or evolving requirements?
Arguments over charting library replacement
The most common reasons for replacement
- Usability issues
If users find it difficult to navigate or use the charting tools, their overall experience can be frustrating, leading to dissatisfaction and potential loss of clients. Although that may seem minor, the appearance and aesthetics of the charts might be unsatisfactory to some users.
- Performance lags
Slow load times and response can severely hamper the real-time analysis required in trading, causing delays and potential financial losses.
- Lack of functionality
Missing features that are considered standard or essential for modern trading may necessitate an upgrade or replacement.
There are other reasons, such as resolving a particular vendor dependency: being tied to a particular vendor’s proprietary technologies might pose risks in terms of pricing, support, and future updates.
- Vendor risk
Switching to a new vendor might introduce unforeseen risks, such as compatibility issues or instability.
- User adaptation
Existing users may have become accustomed to the old chart’s look and feel, making a change potentially disruptive.
Planning the replacement
- CTOs and CPOs
They will drive the strategic direction, ensuring that the new charting library aligns with the company’s goals and technology strategy.
- Software engineers
Responsible for the actual implementation, integration, and migration.
- Product managers
They will help translate business requirements into technical specifications and oversee the project’s alignment with customer needs.
- Business analysts
Engaged in understanding and defining user requirements and aligning them with system capabilities.
- Requirement gathering and analysis
Understanding what is needed from the new charting library.
- Vendor selection
Identifying potential providers and evaluating them based on functionality, compatibility, support, and costs.
- Integration planning
Creating a system design that covers how the new chart will integrate with existing trading systems, including market data feeds.
- Implementation and testing
Developing the solution, followed by rigorous testing to ensure functionality, performance, and compatibility.
- User training and rollout
Educating users about the new tool, followed by a phased rollout.
Potential risks and caveats
- API compatibility
Differences in APIs between the old and new charting libraries might lead to integration challenges, requiring significant adjustments in the codebase.
- Market data feed integration
Ensuring that the new charting library is seamlessly integrated with existing market data feeds is crucial. This could involve understanding different data formats, protocols, and mapping strategies.
- Regulatory compliance
Ensuring that the new charting solution complies with all relevant regulations and standards is a must.
Replacing a charting library inside a trading platform is no trivial task. From understanding the reasons for switching to meticulously planning and executing the replacement, it involves various challenges, risks, and considerations. System design principles must be adhered to at every stage, and the need for seamless integration with other systems, especially market data feeds, must be addressed with expertise and caution.
For CTOs, CPOs, software engineers, product managers, and business analysts working in wealth management or brokerage firms, this guide serves as a roadmap to ensure the transition to a new charting solution is smooth, efficient, and aligned with business goals.
By understanding the potential pitfalls and carefully considering the options, you can make informed decisions that enhance your trading platform’s functionality and user experience.
