Insider Transactions logic

Research
1

Hi all,

I’m trying to look at insider transactions (InsBuyTrans) that is ‘‘the NUMBER of officers and directors that purchased their company’s common stock in the last six months’’.

My issue is that I would like to evaluate the amount of transaction in the last week and since the indicator is calculated on a rolling period I can not exclude that a weekly increase is happening because some transactions from one month ago are dropped. Maybee there is a simple workaround for this but I just don’t see it.

Thanks

Maybe : InsBuyTrans - FHist(“InsBuyTrans”,1)

As far as my understanding goes this would not solve the problem. For example:

Month: 1|2|3|4|5|6|7
Transactions: 9|1|1|1|1|1|1

If today is month 7
InsBuyTrans = Month 2to7 = 6
FHist(“InsBuyTrans”,1) = Month 1to6 = 14

InsBuyTrans - FHist(“InsBuyTrans”,1) = 6-14 = -8

Or am I missing something?
