Determine Maximum / Minimum Value And Additional Count From Variable Range Selection

I have been trying to determine the maximum/minimum value and additional count from a variable range which then I can use to subtract the first data of the range; I have been able to do that for a fixed range but not a variable one.

I have Column A with random positive numbers.

I have Column B with random negative numbers.

I have Column C with random numbers.

I have Column D with random numbers.

I have Column E with random 0’s and 1’s.

I have a set of 1600 cells of numerical data on each of the columns and there will be times when the random 0’s and 1’s from Column D will have appear repeatedly before changing to the opposite number, fx, I will get 7 nr. 1s before I get a 0 (zero).

I have been able to obtain the values in 2 cells within a fixed range:

If the last 8 cells in Column D have been “1” then I do:
F1=MAX(A1:A8)
G1=INDEX(C1:C8;MATCH(9.99999999999999E+307;C1:C8)) ---(Which provides the first number of the range in Column C after Column D has changed from 0 in D9 to 1 in D8)
H1=(F1-G1)

If the next 3 cells in Column D have been “0” then I do:
F9=MIN(B9:B11)
G9=INDEX(C9:C11;MATCH(9.99999999999999E+307;C9:C11)) ---(Which provides the first number of this range after Column D has changed from 1 in D12 to 0 in D11)
H9=(G1-F1)

Additional to this, the COUNT has also been challenging since I want to obtain in Column I, the COUNT of repeated 1’s from each range of 1’s in Column D; and also in Column J the same but for 0’s.

Fx:I18 (size of the range of 1’s originated from D1:D8)
J93 (size of the range of 0’s which consist to be the next range before 1’s were originated)
I12X (size of the range of 1’s which consist to be the next range before changed to 0’s)

However, that only works for a fixed range and continuous updates are made.
