ok tech/a, sometimes I'm not sure if your'e learning or teaching and you sure have a way of slamming some posts. You can make a person wish they had never bothered posting. All a small problem for this forum I would say as it seems a shame to put someone off on their first post.
I think maybe you didn't get the question or just assumed I'm stupid.
However, I'll try again because I would like to know if there is an answer to my question.
I used the term parcels in an attempt to make the question clearer, but I'll try harder with a spelt out example.
EXAMPLE:
Ok, lets say, I sell one parcel of say 100,000 shares and they go to 20 different buyers purchasing various size parcels. The way I see it, the buyer's parcels represent the day's trade, obviously because that is the sale, BUT is there anyway of knowing how many parcels are put up for sale?.
