I used daily to predict short term; Use weekly to predict mid-term.
It works for short-term, mid-term (Like I predicted oil = 40-43, GLD = 109 before using weekly pattern). Sometimes it works better, sometime it works worse, like today, 7+ points off upper bound, and Monday, 12 points off lower bound.
I did not tried long-term yet, since maximum holding time for me are half year, never more than 1 year, so I do not need long-term.
I think I provided enough information, others you need to figure out by yourself.
