Top line might need to be lower (I think it would give too low a target) and the bottom higher but I like how the centre line lines up. I'll see if I can adjust it to line up better with areas of confluence, fibbs etc. and post below. At the moment it probably gives too low a target but its worth considering.
Next most obvious target is the 200 weekly MA at 3160, then 3000 psychological round number, then 2800 pivot point. I can't see anything other than a flash crash move if we were to go below 3k right now and then probably pop back above it.
And as ever not trading advice but just my two cents.
