Back when I was day trading, I only watched videos in Youtube on how to do it. I gotta admit that I did not really earn anything because I was still newbie, but that alone helped me how to use indicators like Bollinger band and the RSI.

As you mentioned that I can relate, I did not read but I was informed to how to use it. Most likely these mediums of learning are personal preference, but sometimes it is situational like in mine where I won't be able to know which to click in Binance to let me do a buy/sell order.
