Very important technical levels to note on the S+P 500 index today

Yesterday the rebound in the S+P 500 filled one of the gaps it left ajar on the daily bar chart the day before, at 5,302. That is because the index reached a high yesterday at 5,312. Just as with the Dow Jones, a late session reversal ensured it could not hold all that gain into the close. The index later fell back to end the session at 5,240, with a more modest rise of 53 points on the day. Now, on Monday the index had reopened at 5,383, before it fell to a low at 5,302. That high, at 5,383 also left open a gap at 5,390.95 from the low point seen on July 25. The low seen last Friday had been set at 5,410.42. So, if you care to look at a daily bar chart of the index, you will see the gap there, between those levels. That could mean the correction we are now seeing is attempting to fill that final gap and that would imply further upside from here on. Perhaps that might even happen later today?  Also to note; some corrective levels of the latest move that are in place, if we take the fall from 5,669 to the recent low, at 5,119 we get the following- 38.2% at 5,329.52 and 50% at 5,394.46. So, you can see; that a 50% recovery of the recent slide perfectly fills that final gap. This makes it pretty compelling right? We shall see. The S+P 500 is coincidentally, currently priced to reopen at around 5,302
