Q: Definition of weekly data.
Can't seem to see this on the site.
Ran into a problem with L.TO
Volume reports as "850868".
When I go to Yahoo!
and add up the volume for the week I get "821700".
I will assume this is a normal problem (where sites do not match).
Anyways my questions follow on two points. Want to start by saying I am not questioning any methods - just want to know how the data is made up.
Q1: Is a week defined as "5 week days" or "5 trading days"?
ie if Monday is closed - and it is Friday today, is the week made up of data based on "Friday (last week) to Friday" or is it still "Monday to Friday" - and in this latter case, the volume would naturally be lower since there was a holiday.
(my gut is that it is always "5 week days". If monday is closed - so be it - that week is considered "Tuesday-Friday")
Q2: What is a WEEK based on? Does it show a week based on the current day + back 4 days?
ie If I look at Friday, it would include for the week everything from Monday - Friday.
ie If I look at Tuesday, it would include the for week everything from Wednesday (last week) to Tuesday this week.
I have heard some sites (Stockcharts?) seem to always gravitate to a Friday as a week. So that if I do a weekly chart on Monday - the volume would be very little because the week is only "one day" so far.
I suppose the "friday closes the week always" is easier to do - but that a 5 day rotation shouldn't add too much work - except the only thing that might be a problem is that every day the chart would look different (from the previous day) - and that might confuse people.
(I suppose I can find out Monday night - but the suspense is killing me softly...)
(all times for each "day" is considered around 6pm - so assume the day has been closed and data updated)
TIA!
