The so-called "floor trading" is only a transaction conducted on the exchange. All orders are settled and delivered with the exchange, and transactions are conducted according to standard contracts. Transactions between banks in the foreign exchange market should be regarded as "floor transactions", and only customer orders that meet the standard contracts can participate. The other is called "over-the-counter market", where customers' orders are not traded on the floor, but directly traded between customers through dealers. This kind of transaction is very popular in Europe and America. At present, dealers in European and American retail foreign exchange markets, such as FXsol, IKON, FXCOM, IFX, Jiasheng and CMC, are OTC markets. The advantage of OTC trading is that you can trade without following the standard contract. At present, most platforms you contact can trade small contracts of 0. 1 lot or even 0.0 1 lot.
