I remember how hard it was for me to find at least something on the Internet on the topic of crypto trading, because in 2009 there were not so many sites specializing in this topic. However, now there are a lot of them, for example, https://goodcrypto.app/relative-strength-index-rsi-indicator-for-crypto-trading-an-ultimate-guide-by-good-crypto/ is the most complete article about the relative strength index of the RSI.It will have to be studied anyway in order to become a competent trader.
