OTC funds can be divided into OTC funds and OTC funds according to different trading places. OTC funds refer to funds that are not listed on the stock exchange but are traded in banks, securities companies, third-party financial platforms or fund companies' direct selling platforms. At present, most funds are OTC funds.

On-site funds refer to securities investment funds that can be listed and traded on the stock exchange like stocks. Common floor funds include closed-end funds, listed open-end funds (LOF), transactional open-end funds (ETFs) and graded funds. There are two investment methods for on-site funds: primary market subscription and redemption and secondary market transaction. The secondary market trading mode of on-site funds is the same as that of stocks, and the share of 100 funds is 1 lot, and the market quotation is used for bidding transactions.
