Hello, I'm Opal, creator of Gemstone Systems, a fledgling entity that develops institutional grade trading systems. Gemstone currently has 3 trading systems, Ice, Saphire, and Jade. In this journal, I will post our daily trades for Ice, a system that trades the Globex S&P e-mini market. At the end of each week, a P&L will be posted based on opening account equity of $25,000US. Ice rarely holds positions longer than 24 hours. Ice is restricted to a maximum stop loss of 10 points ($500) per contract.
