The reason NOT keeps going down is becasue few people trade at this level during this crazy period of tax-loss selling season. I can't say it won't go under $4 (no support until 3.30-3.40. But I doubt it will go that low). But if you want to buy, I suggest you place a couple of orders on the way down instead of a big one. You might want to wait a couple of days. That's your call. Just remember no one can catch the lowest. Indicators are low and needed to be corrected in the next couple of days.

I got some along the way as well, but paid a lot more at 5.43, 4.96 and 4.39. I'd buy more if I still have cash.

PS. You can learn from books, Internet and courses. But there's no shortcut. Keep practising. Learning never ends. Good luck!
