I am a Software Developer, operating my own business in a joint venture with small to medium size financial institutions. My area of expertise is Automated Algorithmic Trading, also known as High Frequency Trading. Nevertheless the success that we experienced in the HFT area I decided to experiment with trading some of my own funds with longer time horizon starting from 2012. I had some interesting successes and also some great failures, as probably many of the participants in this forum. From the position of the retail investor I am a supporter of the "random walk" market theory - doing my research and preparation as much as I can and been aware that at the end of the day the powerful market entities, political influence and other unpredictable events would decide the actual outcome. Interests: software developers and service providers, electronic component manufacturers, mobile phone makers, solar energy, retail, transportation, healthcare.
