In the past, stock markets were physical locations where buyers and sellers met and negotiated. Exchange trading would typically happen on the floor of an exchange, where traders in brightly colored jackets (to identify which firm they worked for) would shout and gesticulate at one another – a process known as open outcry or pit trading.
The exchange floors were often pit-shaped – circular, sloping downwards to the center, so that the traders could see one another.
After that, the traditional pit was replaced by the use of telephone, computers and other technologies. And then with the technological improvement in computers and communication, a new tool was created: The electronic trader platform (ETP), it is a computer system that can be used to place orders for financial products over a network with a financial intermediary.
This includes products such as shares, bonds, currencies, commodities and derivatives with a financial intermediary, such as a brokers, market makers, investment banks or stock exchanges and of course, the foreign exchange market.
Nowadays most of trade operations are made using ETPs, considering that are easy to anyone to access and use, also the cost of transactions can be cheaper than using a traditional stock broker because they are highly trained professionals.
One of the better options to invest in the foreign exchange market. Forex can be traded using the Metatrader 4 or MT4 trading platform. This is a tool that provides many benefits for the user, including a simple interface which is user-friendly, nine time-frames, unlimited charting quantity, large number of technical indicators and line studies, customizable view and others.
Metatrader 4 is free and is provided by most brokers, which mean that is accessible to everyone who wants to invest in Forex.
There are lots electronic trader platforms but Metatrader 4 is prefer by many users cause is simple it can be used by a new trader and also by an expert as well.
