ETF anon from last thread here.

So let's say I forget about the ETFs I just bought today. What's the best way to go about purchasing additional shares?

I know people do stuff like dollar-cost averaging but that usually doesn't happen for growth based things like ETFs that usually slowly and steadily go up right? So do people just buy after a quick dip then forget about it until their next investment opportunity (say, like a monthly paycheck or a yearly bonus comes in)?

And yes I understand that stocks won't always go up forever (ie. VTI taking nearly 2.5 years to recover from the 2008 crash) so even though ETFs aren't a 100% future proof method I still would like to keep investing into them whenever my savings allows for it. So yeah, what's a good way of deciding when to buy ETFs?
