With ETFs, and therefore long term confidence in the relevant market, is "Dollar Coast Average". Invest regularly in order to balance out the fluctuation in the price over time.
Depending on costs, monthly or more. The more entry points, the smoother the overall price.
But monthly is enough in the long term. I myself invest in 2 ETFs every 2 weeks.
The savings plan returns on the 1st. I also thought about buying in between, but it would be nice to have a smooth day so that you somehow have the feeling that the bottom has been reached. But for the last week the price has been collapsing every day at 9:30 New York time. :D Today again. You can set your watch by that.
