you can use weekly but then would have to use 1/2 week, and daily for the cycles maybe even 1/2 day. Remember there's no curve fit to any of this stuff, it's fractal and universal

here's an example weekly GDX, you get the BPT MA turn red and pull back over the ribbon, then you get yoru cycle buy signal on the faster daily chart on the right in June. 

again it's a 2 step process, your 1st set signal is the higher time frame BPT MA Deluxe pinching into the ribbon, and the 2nd set and trigger is a confirming cycle on a SMALLER time frame. In this case the smaller time frame is the daily, the longer time frame is the weekly.  Again it doesn't matter, your longer time frame could be a 2 min chart and your faster one a 1 min, just doesn't matter, it's relevant to the time frame you are following.  in short the time frame you  want to trigger off of is what you use the BPT MA Deluxe on, then you use a faster time frame to trigger.
