DCA everyday including on Sunday.
Discussion
This is the way.
I just switched over last week to daily DCA. Total psychological game changer to see sats stacking every day.

But Jack, the markets aren't open Sundays.
Anyone know if this is possible on River exchange?
Do you make one big monthly transfer from the bank to the exchange to cover the daily buys or is there a daily ACH happening between the bank and the exchange?
If it's the latter, would that put you at risk of being designated a pain in the butt by a bank that already flags every internet transaction (outside of Amazon) as a potential fraudulent transaction?
I can confirm I just put in $100 cash earning 3.8 percent and I put in a recurring buy of 5 bucks daily and it pulls automatically from my cash balance. Worked perfectly!
And Sundays are statistically the cheapest day to buy
Sunday was day one of DCA.
So far so good
