I haven't been a trader on the exchange as long as some, however, 27 years experience has told me I enjoy making my own decisions when I want to make them and when I don't want them. Yes I have lost money many times, but it was my decision and my timing. I have liked very much my leveraged and inverse funds since I discovered them 12 years ago.
