The development of sharia capital market in Indonesia to date has shown a positive thing. This development is seen with the increase of capital market products, the issuance of regulation on capital market and improvement of sharia online trading system (SOTS) facility. SOTS is issued by member companies of the bursa as a form of system that represents the regulation of capital market transactions. SOTS is expected to increase the number of investors, increase the value of capital market transactions, facilitate investors in transactions and obtain company information. While the capital market regulation is expected to change the paradigm of Muslim investors about the capital market and increase the confidence of Muslim investors in stock investment.
