I use pretty much the same combinations with a short term tick chart for determining my entry, if the stoh is out of line with the direction I want to take I usually wait and save a tick or two.
Basically it saved me from going Long earlier because it was overbought.

When you do your weekly, do you use the previous week or do you include the previous five days. I use this for qick calculations.
