MARA is my favorite swing stock!

I’m fairly new to trading but so far I keep buying the dips are MARA and then selling when it gains 15%-20% then when it dips again I do it again. I missed on on this last bull run to its newer high because I sold at $43 which was my target exit. It’s looking like $43 might be my next entry if this bull trend continues as noted by the yellow trend line!
