A Forex broker is a broker dealing in foreign exchange, just like real estate broker who deals in real estate and properties. Simply, a broker is an advisor who advises you about the market. However, the currency market is not the perfect place to play with as a novice and beginner as there are many criticalities involved along with much risk bearing capacities. Novices can very quickly get their fingers badly burnt. But inexperience is not the only reason to consider using a broker to trade in the high-risk (but high potential revenue) international currencies market.
So, the Forex broker is an advisor who advises you about the market and allows you to work for 24 hours a day with major currencies like EUR, JPY, GBP, CHF etc against the US dollar on the spot, i.e. according to the current prices on the international exchange market. But the level of profits depends only on your abilities as well as your timely decision.
Although the role of the Forex broker is relatively redundant as a result of technological advancement and increased awareness, we cannot completely underestimate his role. The new paradigm shift has had something of a democratizing effect on the financial markets, and in the years that have followed a plethora of banks and brokerages have extended the range of their services to a new market by packaging up their online trading systems for the retail market, enabling the more modest investor to trade from their own computer screen - even on the previously out-of-reach currency markets. This is where the real role of broker starts.
