A composite profile helps us get a good understanding of structure as we look at what transpired between buyers and sellers during the day/ week.
But often times , it helps to look inside the structure and see rotations and value where it is developing. The difference between a 30 minute charts and a spilt profile of a MP chart allows you to see the insides as an X-ray would reveal.
Here's the NF-
The shaded blue is the value area of the entire week and the chart shows the activity over the past three weeks in 30 minute slots.
On Friday we had a late spike in the last hour of the day, which brought the markets down 80 points within the hour. On Monday we begin with spike rules, which state that the sellers would have to open lower than Friday lows to continue the auction lower.The move was away from value and around the 5420-40 volume zone ( purple horizontal bars) of last week.
Below that we see an open gap , which has a lot of chances to fill fast should the market continue lower on Monday.
5385 and 5454 are shown as 2 big horizontal high volume points and big resistance for any upmove during the week.
The BN's spike brought it very close to the upper end of that gap we are watching in the other chart of NF.
Below; the gap high the high volume print of 10227 is the weekly support.. Resistance to the upmove remain at 10650/ 10690.
