Link to the 15-minute $NYADV chart with the $NYA, SPY, QQQ price action, in which I have marked up the trading range from last week for the $NYADV, which had displayed negative divergence vs. the SPY price action during Wednesday through Friday, and considering $SPX outperformed the $NYA all of last week and rests at a 3 year ratio high as of Friday's close for the $SPX to $NYA price ratio
