It's simple: Unlike the stocks and, or derivatives, you need not analyze, scan and watch hundreds or thousands of instruments; stick to 4--6 most popular currency pairs or just EUR/USD and leave the fundamental analysis to experts; most of the brokers or reporters publish these as news and, or real-time economic calender.
Low barriers to entry: You would think that getting started as a currency trader would cost a ton of money. The fact is, when compared to trading stocks, options or futures, it doesn't. Online FOREX brokers offer "mini" and "micro" trading accounts, some with a minimum account deposit of $100 or even lower as well. We however, do not recommend trading with that small an equity.
FOREX never sleeps: Trading goes on all around the world during different countries’ business hours. You can, therefore, trade major currencies any time, 24 hours per day. Since there are no set exchange hours, it means that there is also something happening at almost any time of the day or night.
No middlemen: Spot currency trading eliminates the middlemen and allows you to trade directly with the market responsible for the pricing on a particular currency pair; the FOREX market is totally decentralized.
No fixed lot size: In the futures markets, lot or contract sizes are determined by the exchanges. A standard-size contract for silver futures is 5,000 ounces. In spot FOREX, you determine your own lot, or position size. This allows traders to participate with small accounts or little equity per trade.
Go long or short: Unlike many other financial markets, where it can be difficult to sell short, there are no limitations on shorting currencies. If you think a currency will go up, buy it. If you think it will fall, sell it. This means there is no such thing as a “bear market” in FOREX you can make (or lose) money any time.
Low trading costs: Most FOREX accounts trade without a commission and there are no expensive exchange fees or data licenses. The cost of trading is the spread between the buy price and the sell price, which is always displayed on your trading screen. Some FOREX brokers, however, also charge additional commissions which can rob of your hard-earned money quite quickly.
Unmatched liquidity: Because FOREX is a $4 trillion a day market, with most trading concentrated in only a few currencies, there are always a lot of people trading. This makes it typically very easy to get in to and out of trades at any time, even in large sizes.
It's immeasurable: The foreign exchange market is so huge and has so many participants that no single entity (not even a central bank or the mighty Chuck Norris himself) can control the market price for an extended period of time.
Available leverage: Because of the deep liquidity available in the FOREX market, you can trade FOREX with considerable leverage (up to 500:1). This can allow you to take advantage of even the smallest moves in the market. Leverage is a double-edged sword, of course, as it can significantly increase your losses as well as your gains.
Free stuff everywhere!: Most online FOREX brokers offer "demo" accounts to practice trading and build your skills, along with real-time FOREX news and charting services. And guess what? They're all free! Demo accounts are very valuable resources for those who are "financially hampered" and would like to hone their trading skills with "play money" before opening a live trading account and risking real money.
International exposure: As the world becomes more and more global, investors hunt for opportunities anywhere they can. If you want to take a broad opinion and invest in another country (or sell it short!), FOREX is an easy way to gain exposure while avoiding vagaries such as foreign securities laws and financial statements in other languages.
In addition to above, there are a few more reasons and, or considerable facts though somewhat tenuous:
You need not count: The currencies are traded electronically, there is no need to count and re-count or transport the notes and no fear of getting or accumulating any kinds of fake bills.
The "peace of mind": Since we need not interact with the buyers and, or sellers and there would be no returns of the goods and, or refunds of the money in this FOREX or financial market trading.
