I am interested in algorithms and data structures, I care about code quality to make the code more debug-able and bug free. also, I care about performance and to use the right algorithm in the right place.
I've two years of experience as software developer at a well known companies, I worked on projects for banking systems and search engines in which not only correctness but also performance, code readability and maintainability are important.
I traded in Forex too for a while, and programmed some Expert Advisors (EAs), you have a source code of your EA (.mq4 file) not only the compiled (ex4 file), don't you?
