Dynamical linkages for appraisal of finacial instruments

A method to appraise a fund comprising:

• a. At least one computer server, wherein the computer server contains the fund database, wherein the fund database comprises sub-funds of the fund, wherein the fund and each sub-fund are connected hierarchically by links, wherein the fund and each sub-fund are linked to theirs holdings, wherein the holdings for each sub-fund are linked to their assets, wherein the assets are linked to their asset values at specific times, wherein the links of the holdings to their assets and the links of the assets to the asset values are separated, wherein the dynamic appraisal of the fund is derived from traversal queries following the time specific values of the linked structures, wherein the links of the database are represented by a graphical interphase;
• wherein the computer server is programmed to dynamically make queries of new asset values at specific times by means of the internet of things, wherein the computer servers is programmed to appraise the fund without repeating the static information for an asset, wherein the computer server updates the appraisal of the fund by adding new holdings, new assets and new asset values, wherein the computer server updates the appraisal of the fund by creating for each event of a new holding a linked structure, wherein the new linked structure is created at a specific time, wherein the computer server updates the appraisal of the fund each time a holding changes, and wherein the computer server updates each time an asset value changes.
