How are the ADT values are determined?
For MiFID stocks 1. Stocks traded in € – ADT values are taken from CESR database 2. Stocks traded in £ – ADT values are taken from FSA list 3. Stocks not traded in either € or £ – ADT taken from CESR and converted to the relevant currency using an internal LSE FX rate (value rounded to a more suitable number) For non MiFID stocks 1. ADT has been calculated using the same formula as used by CESR based on a years trading volumes. These figures have been calculated in traded currency (value rounded to a suitable number) The link to the FSA’s website explains where the various parts of the detailed calculation can be sourced from.
