How to compute Average Stock ( Base on Jan 2015 Open Stock )

[paulyeo11]

Hi All

I need to compute :-

when at Jan 2015 , Average Stock = 1 ( 1+1)/2=1 , which is Jan Open Stock + Jan Close Stock.

when at Feb 2015 , Average Stock = 1 ( 1+2)/2=1.5 , which is Jan Open Stock + Feb Close Stock.

..

..

when at Dec 2015 , Average Stock = 1 ( 1+12)/2=6.5 , which is Jan Open Stock + Dec Close Stock.

May i know how to do ?

Now my result on Average Stock is wrong.

Enclosed my QV Doc

Hi Sir

I try your dynamic date SET expression :-

Now when i select month = 6 , it display 3 is wrong , it should be 3.5 , because (1+6)/2 = 3.5

This?

Expression:

If(sum(STK_CLOSE) > 0 and sum(STK_OPEN) > 0, RangeAvg(Above(Sum({<month>}STK_OPEN), (RowNo() - 1)), sum({<month>}STK_CLOSE)))

Hi Sir

Now i try to plot the bar chart by year . As i need to view the Avg stock trend by year by month.

Since now i never select year = 2015 , and the result only working for 2014 and not 2015 .

You can do this by fixing the load order in the script. I did a partial reload, you can do it with a regular resident load.

Script:

LOAD date(date_t),

  num(month(date_t)) as [month],

  year(date_t) as [year],

    STK_OPEN,

    STK_CLOSE

FROM

(ooxml, embedded labels, table is data);

FinalTable:

NoConcatenate

ADD Only

LOAD *

Resident data

Order By [date(date_t)];

DROP Table data;

Bar Chart:

Expression: Aggr(If(sum(STK_CLOSE) > 0 and sum(STK_OPEN) > 0, RangeAvg(Above(Sum({<month>}STK_OPEN), (RowNo() - 1)), sum({<month>}STK_CLOSE))), [date(date_t)], year)

Hi Sunny

I open your QV Doc , i notice that for month = 12 , 2015

Amount shouls be 1+12=13 13/2=6.5 , but your equal to 11.5 is wrong.

same for 2014 also wrong.

This?

Expression:

If(sum(STK_CLOSE) > 0 and sum(STK_OPEN) > 0,

RangeAvg(Aggr(Sum({<month>}TOTAL <year> If([date(date_t)] = YearStart([date(date_t)]), STK_OPEN)), [date(date_t)], year), sum({<month>}STK_CLOSE)))

Hi Sunny

What are the purpose of below script ?

FinalTable:

NoConcatenate

ADD Only

LOAD *

Resident data

Order By [date(date_t)];

DROP Table data;

I guess you try to reload and try to sort by date it is ? Now with these code it does work on my side.
