The currency exchange is a 24-hour market. You may decide to trade after you come home from work. Regardless of what time-frame you want to trade at whatever time of the day, there would be enough buyers and sellers to take the other side of your trade. This feature of the market gives you enough flexibility to manage your trading around your daily routine.
Liquidity And Efficiency
When there are a lot of buyers and a lot of sellers, you can expect to buy or sell at a price that is very close to the last market price. The currency market is the most liquid market in the world. Trading volume in the currency markets can be between 50 and 100 times larger than the New York Stock Exchange (Source: Oanda.)
When you are trading stocks, you may have experienced events where one piece of news accelerates or decelerates the price of the underlying stock you may have bought into. Perhaps a director has been kicked out by the shareholders of a company or the company has just released a new product and big investors are buying the shares of a particular company. Share prices can be drastically affected by the actions or inactions of one or a few individuals. So if you are relying on television reports and newspapers to get your news, most of the opportunities or warnings will have come too late for you to take advantage by the time you get them.
The value of currencies on the other hand is affected by so many factors and so many participants that the likelihood of any one individual or group of individuals drastically affecting the value of a currency is minute. Because of its sheer size, the currency market is hard to manipulate. The ability for people to engage in 'insider trading' is virtually eliminated. As an average trader, you are less disadvantaged. You are likely to be playing on relatively equal ground along with all the other traders and investors whom you are competing against.
Note about price gaps:
For those people who have already traded other markets, you probably know about price 'gaps'. 'Gaps' occur when prices 'jump' from one price level to another without having taken any incremental steps to get there. For example, you may be trading a share that closes at $10 at the end of today but due to some event that happens overnight; it opens tomorrow at $5 and continues to go downwards for the rest of the day.
Gaps bring about another degree of uncertainty that may meddle with a trader's strategy. Probably one of the most worrying aspects of this is when a trader uses stop-losses. In this case, if a trader puts a stop-loss at $7 because he no longer wants to be in a trade if the share price hits $7, his trade will remain open overnight and the trader wakes up tomorrow with a loss bigger than he may have been prepared for.
After looking at a couple of forex charts, you will realize that there are little price 'gaps' or none at all, especially on the longer-term charts like the 3-hour, 4-hour or the daily charts.
Volatility
Trading opportunities exist when prices fluctuate. If you buy a share for $2 and it stays there, there is no opportunity to make a profit. The magnitude of level of this fluctuation and its frequency is referred to as volatility. As a trader, it is volatility that you profit from. Large volume transactions and high liquidity combined with fewer trading instruments generate greater intra-day volatility in the currency market that can be exploited by day-traders. The high volatility of the currency market indicates that a trader can potentially earn 5 times more money from currency trading than trading the most liquid shares.
Volatility is a measure of maximum return that a trader can generate with perfect foresight. Volatility for the most liquid stocks are between 60 to 100. Volatility for currency trading is 500. (Source: Oanda.)
In this respect, currencies make a better trading vehicle for day-traders than the equity markets.
Low Transaction Costs
A currency transaction typically incurs no commission or transaction fees. For a forex trader, the spread is the only cost he or she needs to cover in taking on a position. In addition, because of the currency market's efficiency, there is little or no 'slippage' costs.
'Slippage' is the cost involved when traders enter the market at a price worse than the level they wanted to get into. For example, a trader wants to buy a share at $2.00 but by the time, the order gets executed, his gets to buy the shares at $2.50. That fifty cents difference is his slippage cost. Slippage cost affects large-volume traders a lot. When they buy large quantities of a commodity, it oversupplies the market with buy orders. This applies a pressure for the price to go up. By the time they get to buy all the quantities they wanted, the average price they got their commodities would be higher than the price they intended to get them for. Conversely, when they sell large quantities of a commodity, they oversupply the market with sell orders. This applies a pressure for the price to go down. By the time they finish selling all their commodities, their average selling price is less than what they initially intended to sell them for.
Due to lower transaction costs, minimum slippage and strong intra-day volatility, individuals can trade frequently at small costs. As an approximate, you may only expect to have a spread of 0.03% of your position size. To give you an example, you can buy and sell 10,000 US Dollars and this will only incur a 3-point spread, equivalent to $3.
Leverage
There are not a lot of banks or people who would lend you money so that you can use it to trade shares. And if there are, it would be very hard for you to convince them to invest in you and in your idea that a certain share is going to go up or down. Therefore, most of the time, if you have a $10,000 account, you can only really afford to buy $10,000 worth of stocks.
In currency trading however, because you use 'borrowed money', you can trade $10,000 of a currency and you only need anywhere between fifty (For a margin lending ratio of 200:1) to two hundred dollars ( For a margin lending ratio of 50:1) in your trading account. This makes it possible for an average trader with a small trading account, under $10,000 to be able to profit sufficiently from the movements of the currency exchange rates. This concept is explained further in The Part-Time Currency Trader.
Profit From A Bull And Bear Market
When you are trading shares, you can only profit when the price of a stock goes up. When you suspect that it is about to go down or that it is just going to be moving sideways, then the only thing you can do is sell your shares and stand aside. One of the frustrations of trading shares is that an individual cannot profit when prices are going down. In the currency market, it is easy for you to trade a currency downward so that you can profit when you think it is going to lose value. This is easy to do because currency trading simply involves buying one currency and selling another, there is no structural bias that makes it difficult to trade 'downwards'. This is why the currency market has been occasionally referred to as the eternal bull market.
