The playbook calls for a vigorous attempt to get back over that support line — and then fail. So its no surprise that futures are up strong today.
We know that forecasting is folly, and the shorter the time line, the more random the market action is. However, if I were a gambling man, the bet I would make is for a rally right back to that break line, followed by a move lower.
Of course, this technical stuff — support and resistance lines — is just voodoo to some of you. But its how many Wall Street traders manage their risk profile and adjust to what is otherwise random noise. YMMV.
