What is an Edge?
We often hear traders discuss the term ‘edge’, and it is a term that has come to have different meanings for different traders. In the real sense of the word, an “edge” is a statistical advantage, something that puts the odds of success slightly in one’s favor. We will address this, as well as other means that a forex trader can use to gain an advantage.
The Statistical Edge
For instance, in the popular card game called “blackjack” (also known as “21”), the overall odds of the game are very close to 50-50, with an initial advantage or “edge” slightly in favor of the casino. However, a skilled player who understands card-counting techniques can gain the advantage as hands are dealt and cards are eliminated from the deck. By tracking the cards that have already been dealt, the card counter knows which cards remain in the deck, and can therefore gauge the odds as to whether or not he or she will receive a favorable card on the next “hit”. He or she also knows the probability as to whether the dealer’s hidden card is favorable or unfavorable.
Note that the casino sells books that teach players how to gain this edge, yet if a player is caught successfully counting cards, he or she will be escorted out of the casino. Does that make sense? Why would the casino show you how to gain the edge, and then kick you out of the casino once you begin to apply it? The answer is, the casino understands human nature. It knows that most people will not have the discipline to stick with a system, or will use it incorrectly. So, it can freely sell the book knowing that the techniques taught within it are unlikely to be applied correctly.
Please note (and this is very important to understand) that counting the cards correctly does not ensure a successful outcome for each hand, and the card counter does not know which card will be dealt next. The order of the cards in random, and the only thing that the card counter gains is a slight advantage, or “edge” over the casino, not a guarantee of victory.
What good is a slight advantage? Why go through all of this trouble to increase the odds to slightly better than 50-50 in your favor? The fact is that a slight edge can make all of the difference over time. Casinos are built on the entire concept of the slight edge. For example, consider a roulette wheel. The odds are just slightly in the casino’s favor, yet the casino stays open day and night and keeps those roulette wheels spinning around the clock. Consider all of the trouble that the casino goes through to gain a slight edge; it buys the land, obtains the proper licenses, constructs a building, hires employees, advertises constantly, and for what? To gain an edge that is only slightly in their favor? Are they mad? No, the casino companies are not insane. They understand that having just a slight edge can translate into huge rewards over time.
What does this have to do with trading? Everything. First of all, please understand that I am not equating gambling to trading, although there are many traders who truly are gambling in the worst sense of the word. That is because many gamblers, and many traders, are chasing excitement and thrills instead of executing a carefully thought out plan. A good trading plan tilts the odds slightly in the favor of the trader.
What if we believe we have a good plan, but after implementing that plan for a short time we have losses. Does this mean the trading plan is no good or does not work? Let’s go back to the casino and consider how they would handle a similar situation. If the casino loses money on a roulette wheel for the first week or two, will they remove all of the roulette wheels from the casino? Of course not, the casino understands that over time, their edge will manifest itself. The casino is not trying to win every spin of the wheel; it knows that in the long run it will come out ahead, regardless of what occurs on a day-to-day basis. The casino wins because it does not become impatient or emotional and abandon the plan just because it doesn’t work right away.
If we can learn to think like the casino, and exercise patience and discipline, we can succeed in the same manner as the casino. Unfortunately, because many traders have unrealistic expectations regarding the speed with which their edge will manifest itself, they abandon their plan, and with it their edge, at the first sign of difficulty. Now the trader is at the mercy of the market, he or she has surrendered their edge, most likely due to impatience with an unfavorable early result. Successful traders realize that even a good plan often is not immediately successful, and they do not abandon their trading plan at the first sign of trouble. After all, without an edge, there is no reason for the trader to expect to become successful.
Interest – An Overlooked Edge
Often, we can gain an edge by exploiting a component of the market that is frequently overlooked. Let’s take a look at one of the most overlooked edges in trading, something that is unique to forex trading. Forex traders have the opportunity to essentially capture dividends every day. I’m speaking about interest charges and credits. Most of us are familiar with interest charges and credits, but maybe we have not considered what a major difference they can make in our accounts.
If you’re not familiar with how interest payments work, it is simple. Each currency yields a certain amount of interest, as determined by the monetary policy makers of each nation or nations represented by the currency. Policy makers raise these interest rates to try to stimulate growth, and they lower them to slow growth and fight inflation.
For example, the European Central Bank has determined that a two percent rate of interest is currently the appropriate interest rate for countries that use the Euro as their currency. The Monetary Policy Committee has determined that the United Kingdom’s ideal rate is four and one half percent (and has indicated that the rate is likely to fall), and the Federal Open Market Committee has set the current United States benchmark interest rate to three and one half percent (and has indicated that the rate is likely to rise). For a listing of the benchmark interest rates (as of August 21, 2005) of some of the most commonly traded currencies, please see

When we trade a currency pair, we are actually long one currency and short the other currency. Any time we are long any currency pair, we are long the first member of the pair, also known as the base currency, and we are short the second member of the pair, also known as the counter or quote currency.
Many traders don’t give a second thought to paying interest rate charges, and never receive interest rate credits because they are using maximum leverage, for example leverage of one hundred-to-one, two one hundred-to-one, or even higher. Most market makers offer the possibility of earning interest rate credits in exchange for the trader using a lower level of leverage, such as fifty-to-one, yet many of us never consider this possibility. Maybe this is because we feel the interest rate charges and credits are insignificant, but institutional traders and hedge funds often base their entire trading strategy on collecting interest. This type of trade is known as interest rate arbitrage or the “carry trade”.
Now I’m not suggesting that individual traders should focus on carry trades and become long term traders, but I would like you to at least put yourself in a position so that you are not constantly giving interest away. By reducing your leverage slightly you can collect interest on some of your trades, and while it may not seem like much money at first, over time you will see that this has a very positive effect on your profit and loss statement. Let’s see how this might work.
A standard sized lot in forex trading is 100,000 units of currency, however because of the tremendous available leverage we can control one lot of a currency pair with just a fraction of this amount. If we are using leverage of 50-1, we can control one lot of a currency pair with 2000 units of currency. For the purpose of this example we will use $2000 U.S. Dollars to control one lot. We will use the New Zealand Dollar/ Japanese Yen (NZD-JPY) currency pair for our example.

As we can see from the trading station (please see Image 2), the New Zealand Dollar/ Japanese Yen (NZD-JPY) currency pair pays interest to those who are long the pair and charges interest to those who are short the pair. Those who are long the pair can collect an average of $12.65 USD every day, and those who are short the pair will pay the same amount. Let’s multiply $12.65 USD by 365, the number of days per year that we can collect interest, and we see that if the trade were to be held for a year, the trader will collect interest in the amount of $4617 USD per lot. Remember, we only had to put up $2000 USD to control each lot traded, so after one year this trader shows a tremendous gain vs. the size of his or her investment, even if the currency pair has not moved in his or her favor.
Another trader who is also long the currency pair, but does not have the proper leverage to collect interest, will pay $4617 per lot USD over the course of a year. Both traders placed the same trade (long NZDJPY), but the trader who collected interest earned $9234 U.S. Dollars ($4617 x 2) per lot more than the trader who paid interest.
If you always pay and never receive interest, take a look at your own account and see how much interest you paid in the past year. Now calculate how much you would have paid or received if you had set your account to a level of leverage that would have allowed you to collect interest. While the amount may seem small on a daily or per-trade basis, over the course of a year interest credits and charges can often make the difference between a profitable year and a losing year.
While we as individuals don’t always see the importance of these interest credits and charges, institutions and hedge funds certainly do understand their significance and often trade in ways specifically designed to capture that interest credit. But traders who work in shorter time frames are also subject to interest charges and credits, so how can short-term traders take advantage of this situation?
One way that short term traders can profit from interest is by considering the interest credits and charges before entering a position. Suppose we have two potential trading opportunities, one that will result in an interest rate credit, and one that will result in an interest rate charge. If all other considerations are equal, in other words if both trading opportunities are of a similar quality and have similar profit potential, we could take the trade that offers interest. While we know that we cannot affect the outcome of any one individual trade, we can at least control the interest factor, which may seem like a small edge but as we learned at the casino, small edges can yield large profits over time.
Another important point about interest credits and charges relates to that day of the week, usually the end of the Wednesday trading day, when the interest credits and charges are normally three times the amount charged or credited on every other trading day. Why does this happen? Interest is charged or credited daily, but is not distributed or collected on the weekend. So we have a three-day period, Friday, Saturday, and Sunday, when interest builds up. This three-days worth of interest would be charged or credited on Monday, except for the fact that in the spot forex market, settlement is pushed back two days, so it is normally credited instead on Wednesday. If one of the countries involved in the currency pair has a bank holiday, we might see a four-day interest payment. We need only hold the currency pair for a few minutes to collect that four-day interest payment.
This is not to say that the entire trade should be based on capturing the interest rate payment, but if for example the Great Britain Pound/ Japanese Yen currency pair is in an uptrend (the yield on the Pound is considerably higher than the yield on the Yen), and the trader sees a good entry point for a long trade, then that three or four day interest payment is the “icing on the cake”. As long as the trade itself makes sense, the additional gains generated by the interest will add to your account balance. Conversely, if the Great Britain Pound/ Japanese Yen currency pair is in a downtrend, and it is just an hour or two before a large interest payment will be charged, then the trader might reject that trade, or at least wait until after the interest charges have occurred before entering the trade.
The “Insight” Edge
It has been said that the definition of insanity is doing the same thing over and over again, and expecting a different result. Trading is the same way; we have to determine what is working and what is not. We need to know the answers to some important questions. For example, which currency pair is your most profitable? Which one is your least profitable? Which types of trades tend to work the best for you? Which trading techniques are the most or least profitable in your trading? What is your level of success for trading breakouts or pullbacks? It’s important to be able to determine what it is we are doing correctly and what we are doing that may be harming our overall results.
One way that we can gain insight into our trading is by keeping a journal. It may seem like a lot of work but once you get into the habit of doing it, it's really very easy and after a while it becomes second nature. A trader who keeps a detailed journal can look back on prior trades and know what is working, what is not working, and which pairs are the most profitable for his or her style of trading.
It’s easy to keep a journal; if you are on your computer and you see a trading opportunity, open up a word document and note the currency pair, the time, the entry point, the location of the stop, and other important information, along with a short explanation of your thoughts at the time of the trade. You can even take a screenshot of your chart and paste it into the word document. Then in the future when you look back and review your trades, you will be able to determine how different situations impact your trading, in both a positive and a negative manner.
When you look back on your past trades, find your number one weak spot and eliminate it. For example, you may find that every time you trade a certain currency pair, you lose money. At least for the time being, stop trading that currency pair. At the same time, examine your successful trades; is there a common denominator? Is there something that works for you on a consistent basis? If there is, then place more emphasis on whatever it is that is working for you.
Another thing that you will notice is that your thought processes will change over time. At some point, you will look back on your old trades and say, “What was I thinking? I would never place that type of trade today!” Once you have reached that point, congratulations will be in order, because you will have witnessed the evolution of your own trading style. You will know your strengths and weaknesses, and you will be able to make the most of your strengths, and reduce the negative effects your weaknesses.
The Mental Edge
Trading is not easy. Even a short losing streak can cause sleepless nights and self-doubt. If we are not able to maintain a positive mental attitude, it becomes much more likely that we will abandon our trading plan and our risk management rules.
When trading becomes difficult, we need to closely examine what it is we are doing. Is our plan a good one? Are we implementing our plan correctly? Do we have the discipline to continue to execute our plans? One more important question to ask is, has this losing streak affected my mental attitude? After all, it’s easy to have a positive attitude when you are winning; but it is inevitable that even the best traders go through difficult times. The great thing about a good mental attitude is that it will have a positive effect not only on your trading, but on other aspects of your life as well. Try to see past short-term difficulties and understand that trading is a marathon, not a sprint.
Recognize that there are traders whose success can serve as an inspiration. For example, consider John Henry, a farmer from the Midwestern United States. As a farmer, Mr. Henry learned to use the futures market to hedge his crops, and eventually he began to trade the markets full time. Now recognized as one of the most successful traders in the world, he is the founder of John W. Henry & Co. the second-largest Commodities Trading Advisor in the U.S. Mr. Henry is also the principal owner of the U.S. championship baseball team, the Boston Red Sox, purchased at a cost of $700 million USD.
Read books that will support you in your work and aid you in your goals, such as the Market Wizards series by Jack Schwager and Success Through a Positive Mental Attitude by W. Clement Stone and Napoleon Hill. Schwager’s books give the reader true insight into the minds of successful traders, while the book by Clement and Hill gives the reader advice on how to become successful in any venture. Books such as these can show us not only what is possible in our profession, but also in many other aspects of our lives.
If a trader applies the edges we discussed today, he or she could see a significant change in his or her trading results. A small edge can make a big difference, and in the long run it can mean the difference between success and failure for a trader.
