Hi DC --
I attempted to build these Kagi's a number of years ago,
and they are a pia to build -
I think Z used a 4% price change to get a new direction -
I found that you really need to adjust that depending on the product.
then you need to view each chart daily - do the math - and then make the required changes,
BUT you can go weeks with NO direction change.
and you wind up with - ta da - a point and figure chart - or something very close to a pnf chart.
lot of work, not much benefit for me ..
stay warm up there : )
