QuantSoft's trading systems are inspired by data analysis techniques of high energy physics experiments. Strong emphasis is placed on data collection, data integrity, and unbiased statistical analysis. QuantSoft's back-testing and online systems are an adaptation of particle detector software libraries. All trade activity is monitored for the most 2000 liquid U.S. securities. Momentum indicators are used to identify trending behavior at various time horizons ranging from days to months. Abnormal pricing behavior and patterns in the momentum signals are used to identify mean-reverting profit opportunities. The trading system operates autonomously on tick-level price and volume data. At various times throughout the day, our order management system takes the current investment opportunities, incorporates them into our overall portfolio, and submits baskets of algorithmic orders.
