Here is an hourly chart of day session e-mini trading. I think last night's low at 1037.25 ended the drop from 1099. At the low the market had penetrated the rising, green dash trend line by about 3 points, had matched almost exactly the size of the late-September to early-October reaction (green dash rectangle), and had dropped just a tad below support at 1039 defined by the late August temporary high point (horizontal red dash line). This morning's rally has been persistent and has carried the market well above the midpoint of yesterday's day session range at 1049.25. All these signs are evidence that the drop from 1099 is over.
The initial leg up will probably match the size of the biggest reaction on the way down - about 25 points (purple rectangles). This would bring the e-minis up to 1062-63, a level that is also midpoint resistance (purple dotted line). After a reaction from there which should end at a higher low the market will resume an advance that I expect will carry it to 1120 or higher.
