I have been working on (semi-)automated trading systems for a few years mostly in stocks, futures and a bit of forex. I have tried / been using various platforms over the years and have discovered Portfolio 123 early 2014 - which I really like as it allows to design strategies based on fundamentals not technical analysis.
My background is in physics & engineering
I am currently working full time so solely working on low-maintenance strategies (i.e. no day-trading).
