I am very grateful to Frederik for developing the required custom Sierra Chart Studies that I so much needed for my trading. Frederik has amazing skills in building sophisticated studies, he is professional, efficient, very responsive, helpful and and highly skilled in Sierra charting software. I am particularly grateful for his AutoTrader which is a REAL masterpiece work literally allowing you to run any trading strategy in auto regime. It made trading enjoyable for me. It is also an amazing tool you can use to back-test trading ideas. Highly recommended!
