The five decimal places in the foreign exchange market first appeared around 2008 1 1 month. The earliest transaction was designed at the request of MT5. At that time, the MT4 trading software had just started, and many foreign exchange companies were still trading on the web. There are not many companies that use MT4 as electronic trading boards, and most of them are small companies.

Then, with the depreciation of the US dollar, there are more and more poor people in the US dollar, and the number of foreign exchange accounts opened by many large companies is greatly reduced, while more and more people and companies use MT4, while MT5 is basically not used.

MT4 became the mainstream trading software on 20 1 1, but the foreign exchange quotation at that time was still four decimal places. By 20 12, with the deepening of mainstream companies using MT4 as trading software, foreign exchange quotations gradually take five digits after the decimal point. Therefore, the five decimal places that are truly recognized by the market should be the year 20 12 that everyone sees.
