S&P Weekly cycles
S&P completes the March high target @ 1548.
There's a breakout of the Weekly highs @ 1533 and often that can extend up into next week's highs @ 1564....
However, there's a Friday high pattern and if it's below 1548, then there's a short-term (2-day) pull-back into 1533/34
1533/34 is seen as a multi-day Support level.
