calculating return in a range

[kman]

Hi,
I have a range of stock prices. with indication for buy or sell. and i
want to calculate the return of the range for example :

buy 522.73
buy 527.9
buy 528.81
buy 532.33
buy 535.1
buy 536.23
buy 537.03
buy 538.57
sell 537.54
sell 532.86
sell 538.14
sell 533.08
buy 531.22

I want to calculate the return for the first buy signal. the range is
from the start to the first sell signal 537.54- 522.73
then the sell range untill the first buy signal 531.22- 537.54
and so on....

See my answer in your OTHER post. Not necessary or desirable to post in more

Another response to try out, as posted just
to your earlier post in .worksheet.functions
(as Don has advised, please do not multi-post ..)

Another play to try ..

A sample construct is available at:

Calculating return in a range_kman_wks.xls

Assuming the data as posted is in cols A and B, row1 down
Put in C1: =IF(A1="","",COUNTIF($A$1:A1,A1))
Put in C2: =IF(A2="","",IF(A2=A1,"",COUNTIF($A$1:A2,A2)))

Put in D1: =IF(C1="","",A1)
Copy D1 down to D2

Put in E2, array-enter the formula (i.e. press CTRL+SHIFT+ENTER):
=IF(A2="","",IF(A2=A1,"",B2-INDEX(B:B,MATCH(1,($C$1:C2=MAX(IF($D$12=A1,$C$
1:C2)))*($A$1:A2=A1),0))))

Select C2:E2, copy down as far as required
Col E should return the desired results

Put in C1: =IF(A1="","",COUNTIF($A$1:A1,A1))
Formula above is a little superfluous (clean-up overlooked earlier, sorry)
Simply put in C1: =IF(A1="","",1)
