Well, I'm a tad bored, it's hot outside here in Dallas Tx. So I'm sitting in the AC doing some deep study. Here we have a 30 minute SPY chart. I overlayed a 26 period weighted moving average onto the volume data. Seems we have rising volume on the declines and falling volume on the advances, over the last month. Could mean nothing, seems the futures drive everything. Sure cost less to jam them futures overnight. Then gap the opens.
