I've been getting into trading more seriously lately, and I've come across the term "stock annual leverage cost." It seems like a crucial factor when using margin accounts, but I’m still a bit fuzzy on how it really impacts my trading strategy. How much should I actually be factoring it into my decision-making?

I’ve read varying opinions about whether it’s worth leveraging positions or if it just eats into profits in the long run. For those who use margin often, how do you calculate or think about that annual leverage cost? Do you find it’s something that bites you later, or have you managed to make it work in your favor? Would love to hear your experiences on this!
