Lower low on weekly chart expected soon

According to TD setups rules (T. Demark technichal analysis) lower low are expected:
We have printed today bar no. 9 of a TD buy setup. But as you can see the lowest low was printed during bar 6… This is not sustainable according to the rules…. before we can continue higher… we will need to undercut the low at 2801 SPX (cash).
So careful with longs!
