This system not only deals with trade but also with the resolution of the trade itself. In this system, the stocks are changed to electronic data which are saved in computer. Scriptless trading or trade without documents is a trade system which has the mechanism of resolution and storage of stocks electronically. The problems which arise in the implementation of using scriptless trading in the Indonesia Stock Exchange is how about the validity of the transaction of stocks without any documents (scriptless trading) in the Indonesia Stock Exchange and how about the legal protection for investors in scriptless trading in the Indonesian Capital Market.
