Jim Simons' legendary Medallion Fund is a closed "black box" based on Big Data. Deep Market Level (DML) offers a glimpse into this philosophy. DML levels are not subjective analysis, but objective, algorithmic zones calculated from thousands of sources. Created by Mariusz Maciej Drozdowski's research team (MMD methodology), they focus on Forex – the "global accounting firm." Available with free tools, they help build a market edge "one small spoonful at a time."
