No trading class lol everything you said is absolutely right. Strong stocks can run in the overbought zone between 70-90 for days even weeks, but only strong stocks can do this. I do think this is one of them, but regardless if it runs or not, it is still in the overbought zone. And yes the weekly chart is looking good which is the bigger picture.
Oh but they do not mean very little in sub penny trading. I could show you countless charts where a stock reached 70 and pulled back. It applies to all stocks.
