The invention relates to methods for data graphical representation and can be used for analysing and forecasting exchange trading session data. The inventive method consists in introducing archive information about transactions carried out prior to a current trading session, in determining operational level parameter rating in the form of a difference between price operational parameter ratings prior to a selected time T<SUB>s</SUB> and a price parameter rating at the opening of an archive trading session and in determining, for each transaction of said archive trading session after the time T<SUB>s</SUB>, a current operational parameter rating in the form of a difference between the price operational parameter rating corresponding to a given transaction and the price operational parameter rating at the opening of the archive trading session, wherein the operational level parameter rating and the current operational parameter rating represent the co-ordinates of cells of a two-dimensional table which corresponds to an archive card image, in jointly displaying a selected archive card and a marker, whose one coordinate corresponds to the current price operational parameter rating and the other to the current operational level parameter rating and which is embodied in the form of a difference between the current price operational parameter rating of the transactions of the ongoing trading session and the current price operational parameter rating at the opening of the ongoing trading session, in visually comparing the price operational parameter ratings of the ongoing trading session with the card details and in forecasting the price operational parameter rating changes towards the rating having a higher probability level. |
