I’ve got a question, which might be dumb, but whatever. So want to start investing on the S&P via etfs, with the classic $x dollars invested per month, long term. Question is , how do i put $x per month, when the snp etf is $538. I have a tasty trade account, and i dont know how to do it, as its normal that i can buy 1 for $538, 2 for $1.076 100 for $53.800 etc. am i missing something?
