I'm trying to calculate fuel consumptions for golf course machinery which I have filtered into a sheet below.
https://docs.google.com/spreadsheets/d/1T8G-i9WeSkBE_fmL911_750O29AvtRU0GytLP-1gi_w/edit?usp=sharing
I have manually calculated the consumption for machine 7500 #2, however I'm stuck in terms of creating a formula which will essentially do the same in column H and calculate for all machines listed in column B.
I'd imagine there is some indexing required but I'm battling to reference the last date in a range for a specific machine and then do the calc.
try:
=ARRAYFORMULA(IFERROR(D2:D/(E2:E-VLOOKUP(
B2:B&COUNTIFS(B2:B, B2:B, ROW(B2:B), "<="&ROW(B2:B))-1, {
B2:B&COUNTIFS(B2:B, B2:B, ROW(B2:B), "<="&ROW(B2:B)), E2:E}, 2, 0))))

I use a Google Spreadsheet to keep track of the accounts payable per vendor. There is a sheet per vendor in the Spreadsheet. A simplified sheet looks like this:
When I receive a new invoice, an entry for the amount is made in the Credit column and when I release a payment, an entry for the amount is made in the Debit column. I keep track of the running total in the AC Payable column. I achieve this by using a formula in each cell of the AC Payable column (the example below is from cell E4):
=IF(
ISNUMBER(INDIRECT(ADDRESS(ROW()-1,COLUMN()))),
INDIRECT(ADDRESS(ROW()-1,COLUMN()))+C4-D4,
C4-D4
)
The logic is simple. The running total for row n is calculated by:
AC Payable(n - 1) + Credit(n) - Debit(n)
This setup works fine, except I have to drag the formula into newly added rows. Is there a way to achieve this by using ARRAYFORMULA?
PS: I have found a solution using:
= ARRAYFORMULA(
SUMIF(
ROW(C3:C),
"<="&ROW(C3:C),
C3:C)
-
SUMIF(
ROW(D3:D),
"<="&ROW(D3:D),
D3:D
)
)
I feel this is a suboptimal (The original sheet dates back to 2018. It has a lot of rows) solution since, in every row, it calculates the total of the Debit and Credit columns up to the current row and then subtracts the total of the Debit column from the total of the Credit column.
I am expecting a solution that would take advantage of the running total available in the previous row and not redo the whole calculation per row.
solution for up to 1581 rows:
=ARRAYFORMULA(QUERY(QUERY(MMULT(TRANSPOSE((SEQUENCE(COUNTA(A3:A)*2)<=
SEQUENCE(1, COUNTA(A3:A)*2))*FLATTEN(INDIRECT("C3:D"&COUNTA(A3:A)+ROW(A3)-1)*{1, -1})),
SEQUENCE(COUNTA(A3:A)*2, 1, 1, 0)), "offset 1", ), "skipping 2", ))
skills:
it's fast
it's smart
gets slower more rows you add
dies after 1581 rows
it's based on standard MMULT Running/Cumulative Total/Sum formula:
=ARRAYFORMULA(MMULT(TRANSPOSE((ROW(B1:B6)
<=TRANSPOSE(ROW(B1:B6)))*B1:B6), SIGN(B1:B6)))
but with a modification twist, because you got 2 columns to total
instead of ROW(B1:B6) we use a sequence of count of real data multiplied by two (because you got 2 columns):
SEQUENCE(COUNTA(A3:A)*2)
instead of TRANSPOSE(ROW(B1:B6)) we use again:
SEQUENCE(1, COUNTA(A3:A)*2)
combination of these pieces:
=ARRAYFORMULA(TRANSPOSE((SEQUENCE(COUNTA(A3:A)*2)<=SEQUENCE(1, COUNTA(A3:A)*2))))
will produce a matrix like:
and that's the reason why it dies with lots of rows because while you may think that if you have only 1500 rows in two columns, then formula will work only on 1500*2=3000 virtual cells, but in fact the MMULT formula processes (1500*2)*(1500*2)=9000000 virtual cells. still, it's worth to note, that this MMULT fx is great if deployed on a small scale.
next, instead of *B1:B6 we use:
*FLATTEN(INDIRECT("C3:D"&COUNTA(A3:A)+ROW(A3)-1)*{1, -1}))
eg. with INDIRECT we take only "valid" range of C3:D which is in your example sheet just C3:D5 and we multiply C column by 1 and D column by -1 to simulate subtraction and then we FLATTEN both columns into one single column. the part +ROW(A3)-1 is just an offset because you start from row 3
and the last part of standard RT fx - SIGN(B1:B6) is replaced with one column full of ones:
SEQUENCE(COUNTA(A3:A)*2, 1, 1, 0)
then we offset the output with inner QUERY by 1 because we are interested in a totals after subtraction and finally we use skipping 2 which means that we filter out every second value - again, we are interested in totals after subtraction of D column.
solution for more than 1581 rows:
=ARRAYFORMULA(
SUMIF(SEQUENCE(COUNTA(A3:A)), "<="&SEQUENCE(COUNTA(A3:A)), INDIRECT("C3:C"&COUNTA(A3:A)))-
SUMIF(SEQUENCE(COUNTA(A3:A)), "<="&SEQUENCE(COUNTA(A3:A)), INDIRECT("D3:D"&COUNTA(A3:A))))
skills:
supports more rows
looks less smart
sadly the third argument of SUMIF always needs to be a range
gets slower with more rows
it will get sick if you feed it with 10000 rows
it may kill off your sheet with 11000+ rows
Here'a modification of Ben Collins' running total formula
=ARRAYFORMULA(
IF(ISBLANK(A2:A),,
MMULT(TRANSPOSE((ROW(C2:C)<=TRANSPOSE(ROW(C2:C)))*C2:C),SIGN(C2:C))-
MMULT(TRANSPOSE((ROW(D2:D)<=TRANSPOSE(ROW(D2:D)))*D2:D),SIGN(D2:D))))
yet another alternative to MMULT:
=INDEX(QUERY(FLATTEN(QUERY(QUERY(TRANSPOSE(QUERY(QUERY(TRANSPOSE(
(SEQUENCE(COUNTA(A3:A)*2)<=SEQUENCE(1, COUNTA(A3:A)*2))*
FLATTEN(INDIRECT("C3:D"&COUNTA(A3:A)+ROW(A3)-1)*{1, -1})),
"offset 1", ), "skipping 2", )), "select "&QUERY(
"sum(Col"&SEQUENCE(COUNTA(A3:A))&"),",, 9^9)&"' '"),
"offset 1", )), "where Col1 is not null", ))
but again, LTE (<=) limitation of 10M cells won't let you use more than 1581 rows in your case or 3162 rows in the standard cumulative sum case
(1581 rows * 2 columns) raised on 2nd power < 10 million cells
(1581*2)^2 = 9998244
how to calculate monlthy std diviatoin of daily returns in google sheets using google finance api?
I think we need to use QUERY()but I am not sure how to form single data set in QUERY() by calling googlefinance() two times
So far
:
My stock symbols are in Column A in sheet .
I want to calculate monthly volatility as mentioned in
https://www.investopedia.com/articles/investing/102715/computing-historical-volatility-excel.asp
I want have a colum that has monthly history volatility against the symbol in colum A :
=QUERY(QUERY(
{
ARRAY_CONSTRAIN(GOOGLEFINANCE("NSE:"&A2, "close", workday.intl(TODAY(),-5), workday.intl(TODAY(),-1), "daily"), 4, 2),
ARRAY_CONSTRAIN(GOOGLEFINANCE("NSE:"&A2, "close", workday.intl(TODAY(),-6), workday.intl(TODAY(),-2), "daily"), 4, 2)
},
"select Col2",
1), "offset 1",0)
With above query, I am able.to get data range which has last N day price in 1st colum and prev day price in colum 2.
I would like to use and extend this to calculate monthly volatility.
I am not sure how to use this price data range to calculate logarithm and and next calculation.
Thanks
This may be an over-simplification of what you're trying to achieve, but can you use the STDEV function on a range of closing values during a month?
=stdev(query(googlefinance("NSE:"&A2, "close", MonthStartDate, eomonth(MonthStartDate,0), "daily"),"select Col2 offset 1",0))
MonthStartDate would be your cell 'named range' containing your month start. Obviously, days, where the markets are closed, would not bring back a value and the STDEV would reflect this.
If the closing price is too simplistic and you need other attributes, then you could combine them in the query.
I'm looking for a specific Google Sheets formula. I believe it's using COUNTIFS & SUMIF, but I can't work out how to do it, any help would be really appreciated.
So, my "C" column has a number of letter combinations in each cell... These are "FHG" "CS" "MO" and afew others. They are a reference to specific market trading strategies and I'm using this sheet to track every trade I make. So C3 may contain "FHG" C4, "MO" C5, "FHG", C6 "FHG" etc.
In the "I" column, there is a 'profit and loss' column which states how much was generated/lost for that particular row... These are formatted to currency.
At the top of my sheet, I have a summary list of each set of letters and I'm using a COUNTIF statement to work out the total number (instance count) of each particular letter combo and from there, I can work out strike rates, percentages etc.
The thing I can't work out is, 'is there a way to count/sum the relative numbers in the "I" column based on a specific letter combo?' For example, let's say running down today's trades, FHG appears on C3, C6, C8, C12, C16 etc. can I collect and sum the numbers (to create a total) from the corresponding P&L column, I3, I6, I8, I12, I16 etc?
My main aim is to have the following at the top in my "Summary Section":
'Letter Combo/Name Of Trading Technique' - 'Number Of Trades' (Using COUNTIFS down C Column) - 'Total % Win Rate' (Number Of Winners/Number Of Total Trades For Said Strategy - This is done using a separate column of Y or N for winners or losers) - The one that I need help with is - "Total Sum Of Money Generated For Each Particular Letter Combo (Trading Strategy)"...... I've worked out how to do the first 3 columns, but I can't work out how to pick the numbers out from the P&L column (I) based on what kind of trade (letter combo) exists in the corresponding (C) column.
If every trade made the same about of money, this would probably be an easy calculation, but because each return is different, this is proving challenging.
Thanks for any insights :)
try:
=QUERY(A:I; "select C,sum(I) where A is not null group by C label sum(I)''")
or just for SB:
=QUERY(A:I; "select C,sum(I) where C = 'SB' group by C label sum(I)''")
if you want a count too:
=QUERY(A:I; "select C,count(C),sum(I) where A is not null group by C")
I am trying to get the spreadsheet to use the value of L2 as a reference to calculate the cash value at the moment:
From the formula:
=arrayformula(IF(I2:I<>"",$L$2+SUM(INDIRECT("G2:G"&I2:I)),""))
But the lines below always return the same result, in this case 100.
I wonder where I am going wrong in creating this formula
Another detail:
I have made a chart ready to treat this cash growth over time, if you decide to help by looking straight at the spreadsheet, by re-adjusting the correct formula, please also take a look if the chart is working correctly according to the data and the movement of values, always the last row of columns G and H at the beginning of the graph
This is the expected result in Bank Column:
Capture the initial bankroll L2 and from it add the sequence of results achieved in each investment in COLUMN G
Link to spreadsheet
try:
=ARRAYFORMULA(QUERY(L2+MMULT(ARRAY_CONSTRAIN(SPLIT(REPT("0×",
ROW(INDIRECT("A1:A"&COUNTA(D2:D)+1))-1)&
TEXTJOIN("×", 1, INDEX(SORT({INDIRECT("G2:G"&COUNTA(D2:D)+1),
ROW(INDIRECT("G2:G"&COUNTA(D2:D)+1))}, 2, 0),,1)), "×"), 999^99,
COUNTA(D2:D)+1)*1, ROW(INDIRECT("G1:G"&COUNTA(D2:D)+1))^0),
"offset 1", 0))
I have a scoring spreadsheet for a competition I'm working on. Competitors' place/rank are converted into points towards the overall series based on a chart of corresponding values. For ties, the sum of the points covered by all of the tied places are split evenly among the tied competitors (i.e. 2-way tie for 3rd; if 3rd usually gets 10 points and 4th usually gets 8, these competitors will receive (10+8)/2 (2 being the # of tied competitors), so they each receive 9 points).
I have a formula which does this exact calculation:
=IFERROR(IF(ISBLANK($A4:$A),,SUM(INDEX(SeriesPoints, E4:E):INDEX(SeriesPoints, MIN(E4:E + COUNTIF(E$4:E, E4:E) - 1, ROWS(SeriesPoints)))) / COUNTIF(E$4:E, E4:E), 0))
Where 'SeriesPoints' is a 2 column array; column 1 is the places/ranks (1:125) and column 2 is their corresponding point values. Column 'E' is the competitors' rank from the competition.
I have been unable to convert this formula to an ARRAYFORMULA() so I can avoid dragging it down the entire sheet (possibly up to 1000+ competitors over the series).
I'm mildly proficient with MMULT(), so I understood that would be a good approach for switching out SUM(), however, I haven't been able to create a matrix of the values to be summed.
INDEX():INDEX() doesn't work with ARRAYFORMULA() so I've tried switching to VLOOKUP(). With VLOOKUP() I've been able to produce the start and end values of the range of values for a tie, but not the full list. For example, if there is a 3-way tie for 4th, I can produce the respective points for 4th and 6th (the bounds of the tie).
In an attempt to list out even just the numbers from 4:6, I've hit a wall converting what would be a simple ROW() or SEQUENCE() formula to a matrix/array.
The following formula produces an array of the upper and lower bounds of ties or the single place should there be no tie, although the single place gets repeated.
=ARRAYFORMULA(IF(COUNTIF(E$4:E,E4:E)=1,E4:E,{E4:E,E4:E+COUNTIF(E$4:E,E4:E)-1}))
I'm assuming if I can get VLOOKUP({#:#}) to fill properly, I'll be where I need to be.
From here, I feel confident in my abilities to wrap a VLOOKUP() for the actual point values, an MMULT() to sum across these rows for the total, then a simple division to produce the correct point value.

Currently, my workspace is off to the right. The original formula is in F4 and my test codes are working on column G instead of E.
So for sample placements of 1,1,3,3,3,6,7,8 and sample points values of 1000, 850,738,663,633,603,573,550 I expect the output to be 925 for the two 1st place tied competitors, 678 for the tied 3rd places, 603 for 6th, 573 for 7th, and 550 for 8th.
I'd appreciate any and all help!
