How the code is written can impact how efficiently your strategy trades. Having been exposed to so many other trader's and developer's code and to finding solutions to their issues, Dave brings a broad perspective to coding and a deep understanding of just how to effectively and quickly code in EasyLanguage® while avoiding non-obvious pitfalls.
