Also... this is me speculating on where a W5.5 ends. Basically very near, "the top" for a while - so, be risk aware.

Looks like it could be a developing triangle, which fits w/ a w4. If you trade the triangle, use a stop to avoid getting hurt on the possible rapid drop (considering a slight overthrow from a the support trend - to clean some nearby stops), on Sunday night's futures market open.
