If index want to maintain scenario 1, they really need to hold today's low.
真的是这样去lower low，只能是2/19下来这一浪的延续 ，应该不会太深了？
Scenario 1 is "still" valid as index is holding the support so far. Until support is broken, view this as continuation of the bounce.
However, we should never ignore the market signal. So, if we do take out the low, be prepared for scenario 2
