It's not only my own experience, it's proven fact nobody can argue with, exhaustive scientific testing in Multicharts, Supercharts, Tradestation, Strategytester, StrategyBuilder, and GTF platform of every timeframe, pair, strategy, and platform. ALL failed, only one TDI variation breaks even. I learned many years ago not to waste any money on all the s*** out there including books, courses, and seminars. As a software engineer for ten years with university advanced statistics and math education and county trained in scientific observation. I debunked many books over the years including clever "confluence" ploys.
