Here is a 30 minute bar chart of e-mini day session trading for the past 10 days or so. I had to dump my long position when the market dropped below the 936 level on relatively high volume.
You can see that today's volume is not unusual compared with the other days' volume shown on this chart. This makes me think that the market is still going to be contained within the trading range outlined by the green dashed line. I now estimate that today's range will be 925-950 (blue rectangle).
The break below the 936 level coincided with the auction of the 10 year notes today. There will be a thirty year bond auction at the same time tomorrow. Evidently market players are using rising interest rates as an excuse to sell. As I explained in this post, I think this reasoning is faulty. Consequently I think the results of these auctions have bullish implications looking out more than a few days.
