My acorns account says +19 dollars give or take. What I’m confused about is does that mean overalll that’s the money I have gained? Or if I lost 30 dollars a few months ago, does that mean now I’ve gained 19 of that back so I’m still on the hole 11 dollars? Or is it saying overall that is the amount I’ve gained? I’m trying to understand it better but It’s confusing to me. Thanks! 

Btw no I don’t have a ton of money in acorns (or at all in general), but because I am currently so unknowledgable about investing I figured it’s best to start with a small amount to use to teach myself.
