Is there an advantage to daily over weekly/monthly? It seems to me like w/m would make more sense as you'd get less fees?
However, I just tried setting up a new transaction and the fee looks to be $0.99 for a $5 investment. At ~20%, this sort of averaging would no longer be worth it. Like I said before, I guess I've been grandfathered in after the new fees schedule was imposed. Let's see how long it lasts.
