CL was very weak Thur-Fri, a good clue that the retrace in ES was possibly running out of steam. Some guys had the 2640 level pegged as a throwback of the broken TL, but that hit early evening Thur night.
I remember the 2008 decline like it was yesterday. One poster on here tried buying it every day for a few months. I won't mention his name, but it was painful to watch. CL is a widowmaker for those who think they can apply ES/NQ/YM strategies on it.
