in order for readers to have an idea of what these indicators are, what they mean, what are their uses ...im including here the links (just click on the questions in red) to articles in the investopedia and stockcharts.com websites that discuss these indicators  (im supposing that technical analysis experts (TAE) consider investopedia and stockcharts to be credible sources of trading info ...
