PURPOSE: A virtual keyboard on a trading order window of a cyber trading system is provided to input all numerals of a transaction password, an item number(code), a trading amount, and a unit cost using a mouse instead of a keyboard on a virtual keyboard automatically, rapidly, and simply when a cyber trading is ordered. CONSTITUTION: A basic unit keyboard(11) includes arrays of numerals from '0' to '9'. A tenth unit keyboard(12) includes arrays of numerals from '0' to '99'. A hundred unit keyboard(13) includes arrays of numerals of "00", "000", "50", "100", "150", "200", ..., "850", "900", and "950". In addition, a "Back Space" key, a "Clear" key, and a "TAB" key are provided. If a specific cell is selected, a corresponding numeral is inputted on a trading order input space located in a cursor. If the specific cell is clicked twice, a numeral multiplied by "10" is inputted. For example, if the "65" is clicked twice, "650" is inputted. If a right button of a mouse is pressed on a specific cell, a numeral multiplied by "100" is inputted. For example, if the right button of the mouse is pressed on the "98", "9800" is inputted.
