VanKar Trading Corp.


VanKar Trading Corp. was a futures brokerage group established in 2001. As an NFA-registered independent introducing broker, VanKar was founded by two veteran futures industry professionals with over 30 years of combined experience in the futures industry. The company was known for its expertise in the futures markets and its commitment to providing top-quality service to its clients.

SoftAtBest was fortunate to have had the opportunity to work with VanKar on the development of Autotrader, an application that executed futures contracts based on signals generated by Tradestation. This was a pioneering development, as Tradestation did not have this functionality at the time. Autotrader allowed traders to automate their trading strategies and take advantage of market opportunities more quickly and efficiently, while reducing the slippage and errors. In addition to working on Autotrader, SoftAtBest also participated in the full-cycle development of trading systems using Tradestation’s EasyLanguage.

 In 2006, VanKar ceased operations and one of the partners, Emil van Essen, moved into the CTA business with a very successful Spread Trading Program. SoftAtBest participated in the early stages of research and development for this program, providing help with data quality and back-testing. Working on this project gave us a deep understanding of the futures markets and the factors that influence price movements. It also allowed us to develop strong skills in back-testing and cross-validation, which are crucial for ensuring the accuracy and reliability of trading systems.

Emil van Essen LLC


In 2006, Emil van Essen founded his own CTA-registered company, which was focused on the development of a highly successful Spread Trading Program. This system generated average annual profits of 18% from 2006 to 2014, and had an almost 0% correlation to the S&P.

By 2014, the firm’s assets under management had soared to $140 million. In 2021 Emil van Essen merged with Katonah Capital, a systematic futures manager with a unique machine learning approach.

SoftAtBest was proud to have participated in the early stages of research and development of the Spread Trading Program, providing expertise in data quality and back-testing. Our work on this project gave us valuable experience in the futures markets, as the system traded in commodities, equity volatility, and interest rates. The back-testing and cross-validation processes were strictly supervised by Mr. van Essen to ensure the accuracy and reliability of the system.

Bloomberg L.P.


Bloomberg is a financial, software, data, and media company headquartered in New York City. Founded in 1981, the company developed Bloomberg Terminal, its flagship product.

The Bloomberg Terminal is a widely recognized and respected platform in the financial industry, known for its comprehensive and up-to-date market data information, powerful analytics, news and industry communications, delivered through the consistent user interface.

SoftAtBest was pleased to have had the opportunity to provide consulting services to Bloomberg’s news group, retrieving financial data from news and exchange releases. SoftAtBest worked closely with Bloomberg’s team to understand the requirements and develop effective solutions that were integrated into the Bloomberg Terminal. 

One specific project SoftAtBest worked on with Bloomberg involved optimizing the delivery of Tokyo Stock Exchange earnings releases to the Bloomberg Terminals worldwide. This required us to improve the efficiency of TSE’s API and work with Bloomberg network engineers and developers on data path optimization. This was an important project that helped Bloomberg to beat the competing provider and we were pleased to have played a role in its success.

Overall, our work with Bloomberg was a valuable learning experience that allowed us to gain a deeper understanding of the financial data management industry and the tools and technologies used by leading companies like Bloomberg. We are proud to have contributed to the success of Bloomberg and to have had the opportunity to work with such a respected and influential company.
