Commodity exchanges are organizations governed on-site according to democratic principles. Those who trade in the stock market and therefore have to be registered in the stock market are divided into professional groups according to their profession, that is, the type and type of items they trade. Professional committees of 5-11 people are elected from each group. A stock exchange council is established with the participation of 2-3 people selected from each professional committee. Stock exchange boards of directors consist of 5-11 people who will be elected by the council among its own members for 4 years. Additionally, the same number of substitute members are elected. The board of directors elects a chairman and one or two deputy chairmen among its own members for a period of 4 years. There is a general secretary appointed by the assemblies in the stock exchanges.
