Johann Christian Lotter is a classic career changer on the stock exchange. He studied law and physics, worked for a while in the film and television industry and lived in the USA, where he programmed video games. Later, he founded his own software company for film effects and computer games. Then, about ten years ago, when he wanted to expand and for this reason talked to various backers, he found an investor with a special idea: to convert the existing game development platform into a trading platform that could be used for both quick backtests and automated trading. And that's exactly what he did. In the meantime, Johann Christian Lotter and his constantly growing team have already tested more than 1300 strategies for customers.
