Forex is a dynamic, versatile industry, because there are so many different ways of looking at so many different markets. This allows every trader to develop their own trading strategy based on whatever personality you have.

For starters, because most counties across the world have their own medium of exchange, there are tens of thousands of different investment vehicles to chose from, meaning that one can specialize in one region of the global economy for trading, or capitalize on the boarder picture by focusing on the majors.

FX is also versatile in that it follows two broad analytical methods known as fundamentals and technical analysis.
Fundamental analysis involves trading on real economic data or events to predict where a currency pair is going to go. Think the European Central Bank is going to hike interest rates? Why not put in an order to buy euros against the yen to profit?

The counterpart to fundamental analysis is technical analysis, which involves looking at trends in price charts of various crosses. Notice various attempts for EUR/USD to break above a certain level? Why not buy the pair and ride the wave as the break finally comes?

Trades can also be very short term in nature, with positions open for mere minutes, to the broader movements over long periods of time.
The very best in the business, however, know that the successful foreign exchange traders use a bit of both technical and fundamental analysis, leaving you with the flexibility to decide of whatever works for you.
