Great! Really, really exciting to learn this and not be ignorant any longer. Now show us all on ET the SPECIFIC, EXACT set up you back tested and the results of that back test.
WARNING: GIGO ALERT!

Garbage in, garbage out (abbreviated to GIGO, possibly intended to parallel the phrase first-in, first-out) is a phrase in the field of computer science or information and communication technology. It is used primarily to call attention to the fact that computers will unquestioningly process the most nonsensical of input data ("garbage in") and produce nonsensical output ("garbage out"). It was most popular in the early days of computing, but applies even more today, when powerful computers can spew out mountains of erroneous information in a short time. The first use of the term has been dated to a 1 April 1963 syndicated newspaper article about the first stages of computerization of the US Internal Revenue Service.[1] The term was brought to prominence as a teaching mantra by George Fuechsel,[2] an IBM 305 RAMAC technician/instructor in New York. Early programmers were required to test virtually each program step and cautioned not to expect that the resulting program would "do the right thing" when given imperfect input. The underlying principle was noted by the inventor of the first programmable computing device design:
On two occasions I have been asked, "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
âCharles Babbage, Passages from the Life of a Philosopher[3]
It is also commonly used to describe failures in human decision-making due to faulty, incomplete, or imprecise data.
