EasyLanguage code mustdo more than run—it mustbehave as intended.

The Experts’ Expert

Years spent answering the questions that arise after the simple answer fails.

Before joining TradeStation, Dave built a career spanning engineering research and technology leadership. As a new electrical engineering graduate, he was selected for GE’s prestigious Edison Engineering Program. When GE’s fluorescent-lighting operation began adopting the emerging technology of finite-element modeling and Computer-Aided Engineering, David had already demonstrated an unusual aptitude for computational analysis and engineering judgment. Only three years out of engineering school, he was selected to manage the newly created modeling and information technology group. He built and expanded the group as computing technology rapidly evolved, and later served as Director of Information Technology at both Owens Corning and Whirlpool.

David “Dave” Cohn—known as DaveC@TS throughout the TradeStation community—spent five years at TradeStation as an EasyLanguage Engineer and EasyLanguage Specialist. In that role, he supported the TradeStation EasyLanguage Forum, providing more than 17,000 EasyLanguage Forum answers. When other developers reached a problem they could not solve, their support tickets came to Dave. That work gave him unusually deep knowledge of the platform—and he has continued building that knowledge since the early 2000s.

Dave also brings real-world trading experience. It helps him recognize where an apparently straightforward rule meets actual order behavior, market data, gaps, slippage, liquidity, and the other conditions a strategy encounters outside the ideal example. He no longer trades for his own account. That is a deliberate conflict-of-interest policy: his role is to help clients define and implement their strategies—not to compete with them, manage their money, or provide investment advice.

The TradeStation forum contained roughly half a million answers and discussions accumulated over many years. Search results could return thousands of scattered responses—some incomplete, outdated, or incorrect—and seemingly simple questions often required several layers of EasyLanguage knowledge to answer properly. Dave created the Master Post to identify, organize, and connect the forum’s most useful information. Working across that extraordinary breadth of real questions and difficult problems helped develop the unusually deep and nuanced understanding of EasyLanguage that he brings to Emerald’s clients today.

Many Master Post entries contain heavily documented, actual EasyLanguage code—not merely explanations. Together, they form an extensive technical resource shaped by the real questions and difficult problems encountered by the TradeStation community. As with any code example, each should be independently reviewed and tested in the current TradeStation environment before use.
