To provide an electronic transaction system using in-pride probability distribution customized by a user and a graphical user interface for the system.SOLUTION: A computer implemented transaction system 100 calculates market in-pride probability distribution of the future price of tradable assets derived from a realtime price of an asset option to display its graphical expression, allows a user to customize a market in-pride probability distribution graph so as to reflect the user's own insight about a probability that the future price of the assets will be included in a certain price band, and proposes an optimal transaction strategy optimized for profit on the premise of customized probability distribution (in the case of existence) implemented as a combination of options. Combination orders can be modified and/or added by the user.SELECTED DRAWING: Figure 1
