Trading system quality
Van Tharp developed a proprietary measure of the quality of a trading system that he calls the System Quality Number, or SQN. SQN measures the relationship between the mean expectancy and the standard system of the R-multiple distribution generated by a trading system. It also makes an adjustment for the number of trades trading. The calculation, use, and interpretation of the SQN are system extensively in Dr. Tharp discovered that when he applied the SQN formula to the daily percent price change of a stock or an index, it proved to be an excellent measure of trendiness. Tharp also uses a quantitative world model of the markets that shows the strongest and weakest regions, countries, quality, and currencies using the universe of ETFs. Minimum System Quality Number.
