Thanks 8horse that is very helpful. I remember a few years back it was possible to obtain course of sales records revealing which top 20 shareholders were buying and selling because someone sent me detailed weekly records in a spreadsheet form which showed for example. Mr x super fund sell 1,000,000 units 28th December. Etc so it was a more specific list of individual transactions over the course of the week or month that provided specific transaction details including that of the top 20 share holders and also some institutions. I have lost contact with the person who had access to this data and not sure if it is available a y more. Thanks
