Don’t get me wrong, indicators are great tools for getting a weather report and building a set of rules to trade/invest by. They give great context. Years ago I went through many of the most popular indicators and what input variables are used to generate the indicator. You can see the strength and weakness in each this way. Many just look at weather a high or low rsi like it is an oil pressure gauge or something. Knowing how these are generated give such better depth. I am not suggesting they are just tools of the pump and dumpers, if anything pump and dumpers use them because they know some investors have rules about certain levels and they know those investors will follow them.
