Now that we are living under a rock I do this for entertainment and income.
I use StockCharts including a set of one hour interval over one month charts. I scroll through our LI charts plus some others daily.
I have noticed that short and intermediate term many or most of the charts share the same wave counts up and down on the same days. Some charts lead and some lag the trend.
My guess is that t $SPX and SLV are down on Monday.
This is interesting stuff to learn and follow.
Thanks to you Sean.
