Supersonic Charting Solution for One of the Biggest Global Financial Platforms

About the Client

The client is a media platform with 150 mln visitors monthly, quite often topping the finance websites rating in the Alexa or Similarweb ranks globally. The platform provides actual news, real-time market data, and other information relating to the financial markets.

Business Challenge

The client was looking for a charting solution as a core of a new analytical B2C system. DXcharts, being one of the leading charting solutions on the market, became a perfect fit for this goal.

Following the customer needs, DXcharts already provided a comprehensive set of features such as 42 drawings, customizable intervals, 11 chart types, accessibility compliance, etc. Along with the great functionality, impeccable performance was a critical factor to the client: the charting solution had to be working in a high-load environment, a multiple-chart layouts mode, where users launch up to 16 charts at once. It meant that the solution must operate an enormous workload with no productivity or availability loss. None of the then-current market leaders could provide as productive and efficient charts as required.


To solve this task, DXcharts team undertook a series of optimization measures. We managed to reduce the CPU usage, increased FPS, and eventually boosted up the DXcharts performance multiple times (see the Results section). The team made DXcharts work smoothly even in high load conditions, such as rendering 8, 12, and 16 charts with market data and indicators updating in real time.

As the final step, we tested DXcharts under extreme workload, employing heavy configuration that would exceed the setups of the most sophisticated users. Devexperts ran the tests several times to ensure that DXcharts will sustain the future performance challenges beyond the project requirements.

Charting is an essential tool in a trader’s toolbox. As a product manager, I always wanted DXcharts to be the best “swiss army knife’’ there is. This project was quite challenging, I would say we unlocked the whole new level: the growing functionality and ease of implementation should now be accompanied by supersonic speed.

It is so delightful to see it through. I truly believe that the users would enjoy it.

I enjoyed working with Devexperts who competed to become our charting vendor. Their team did go the extra mile to satisfy the most demanding requirements of our users – analysts and traders with multi-monitor configurations.
