Is poc a form of analysis of what other traders are doing? If it is, it won't work because 90 percent of traders lose money. If anything, it would be a contrarian form of analysis.
My setup is volume- and order flow-based. You can see where the big money goes to. There are volume clusters at price levels (support and resistance zones) at which the direction often changes.
My short-term momentum is still up at the moment. May be getting closer to bellister's 3020 POC. SPX Blaster -- note that your cycle high really may come on 9/24 and then we see the move lower.
