Last week I was looking at the decent looking resistance trendlines and growing mass of negative RSI divergence on both SPX and NDX. Over the course of the last week first the SPX resistance trendline broke, though this could still be a bearish overthrow, and then the daily RSI 14 sell signal failed on Friday, and then the SPX RSI 5 sell signal failed yesterday. That is very unusual and does not favor a significant high being made here.
