What is the meaning of the name iSigma?
The “i” stands for infinite. Sigma is the Greek letter used to represent the second moment of a distribution (equivalent to standard deviation). Our trading method is based in large part on the market model developed principally by Benoit Mandelbrot who initially put forth the idea that price changes have an infinite second moment. For a better understanding of why this is important to the effectiveness of our method, see this article.
