FOREX ARTICLES

Brett N. Steenbarger, Ph.D.



There are quite a few books written on how to make money in the market. Some of them are even written by people who have made money as traders! What you don't see often, however, are books or articles written on how to lose money. “Cut your losers and let your winners run” is commonsensical advice, but how do you determine when a position is a loser? Interestingly, most traders I have seen don't formulate an answer to this question when they put on a position. They focus on the entry, but then don't have a clear sense of exit—especially if that exit is going to put them into the red.

One of the real culprits, I have to believe, is in the difficulty traders have in separating the reality of a losing trade from the psychological sense of feeling like a loser. At some level, many traders equate losing with being a loser. This frustrates them, depresses them, makes them anxious—in short, it interferes with their future decision-making, because their P & L is a blank check written against their self-esteem. Once a trader is self-focused and not market focused, distortions in decision-making are inevitable.

A particularly valuable section of the classic book Reminiscences of a Stock Operator describes Livermore 's approach to buying stock. He would sell a quantity and see how the stock responded. Then he would do that again and again, testing the underlying demand for the issue. When his sales could not push the market down, then he would move aggressively to the buy side and make his money.

What I loved about this methodology is that Livermore's losses were part of a grander plan. He wasn't just losing money; he was paying for information. If my maximum position size is ten contracts in the ES and I buy the highs of a range with a one-lot, expecting a breakout, I am testing the waters. While I am not potentially moving the market in the way that Livermore might have, I still have begun a test of my breakout hypothesis. I then watch carefully. How are the other averages behaving at the top ends of their range? How is the market absorbing the activity of sellers? Like any good scientist, I am gathering data to determine whether or not my hypothesis is supported.

Suppose the breakout does not materialize and the initial move above the range falls back into the range on some increased selling pressure. I take the loss on my one-lot, but then what happens from there?

The unsuccessful trader will respond with frustration: “Why do I always get caught buying the highs? I can't believe “they” ran the market against me! This market is impossible to trade.” Because of that frustration—and the associated self-focus—the unsuccessful trader does not take any information away from that trade.





In the Livermore mode, however, the successful trader will see the losing one-lot as part of a greater plan. Had the market broken nicely to the upside, he would have scaled into the long trade and likely made money. If the one-lot was a loser, he paid for the information that this is, at the very least, a range-bound market, and he might try to find a spot to reverse and go short in order to capitalize on a return to the bottom end of that range.

Look at it this way: If you put on a high probability trade and the trade fails to make you money, you have just paid for an important piece of information: The market is not behaving as it normally, historically does. If a robust piece of economic news that normally sends the dollar screaming higher fails to budge the currency and thwarts your purchase, you have just acquired a useful bit of information: There is an underlying lack of demand for dollars. That information might hold far more profit potential than the money lost in the initial trade.

I recently received a copy of an article from Futures Magazine on the retired trader Everett Klipp, who was dubbed the “Babe Ruth of the CBOT”. Klipp distinguished himself not only by his fifty-year track record of trading success on the floor, but also by his mentorship of over 100 traders. Speaking of his system of short-term trading, Klipp observed, “You have to love to lose money and hate to make money to be successful…It's against human nature what I teach and practice. You have to overcome your humanness.”

Klipp's system was quick to take profits (hence the idea of hating to make money), but even quicker to take losses (loving to lose money). Instead of viewing losses as a threat, Klipp treated them as an essential part of trading. Taking a small loss reinforces a trader's sense of discipline and control, he believed. Losses are not failures.

So here's a question I propose to all those who enter a high-probability trade: “What will tell me that my trade is wrong, and how could I use that information to subsequently profit?” If you're trading well, there are no losing trades: only trades that make money and trades that give you the information to make money later.

Bollinger bands are one of the most popular technical indicators for traders in any financial market - stocks, bonds or foreign exchange (FX). Many traders use them primarily to determine overbought and oversold levels, selling when price touches the upper Bollinger band and buying when it hits the lower Bollinger band. In range-bound markets, this technique works well, as prices travel between the two bands like balls bouncing off the walls of a racquetball court.



Yet as John Bollinger was first to acknowledge, "tags of the bands are just that - tags, not signals. A tag of the upper Bollinger band is not in and of itself a sell signal. A tag of the lower Bollinger band is not in and of itself a buy signal". Price often can and does "walk the band". In those markets, traders who continuously try to "sell the top" or "buy the bottom" are faced with an excruciating series of stop-outs or worse, an ever-mounting floating loss as price moves further and further away from the original entry.


Perhaps a more useful way to trade with Bollinger bands is to use them to gauge trends. To understand why Bollinger bands may be a good tool for this task we first need to ask - what is a trend?

Trend as Deviance
One standard cliché in trading is that prices range 80% of the time. Like many clichés this one contains a good amount of truth since markets mostly consolidate as bulls and bears battle for supremacy. Market trends are rare, which is why trading them is not nearly as easy as it seems. Looking at price this way we can then define trend as deviation from the norm (range).

The Bollinger band formula consists of the following:
BOLU = Upper Bollinger Band
BOLD = Lower Bollinger Band
n = Smoothing Period
m = Number of Standard Deviations (SD)
SD = Standard Deviation over Last n Periods Typical Price (TP) = (HI + LO + CL) / 3
BOLU = MA(TP, n) + m * SD[TP, n]
BOLD = MA(TP, n) - m * SD[TP, n]

At the core, Bollinger bands measure deviation. This is the reason why they can be very helpful in diagnosing trend. By generating two sets of Bollinger bands - one set using the parameter of "1 standard deviation" and the other using the typical setting of "2 standard deviation" - we can look at price in a whole new way.

In the chart below we see that whenever price channels between the upper Bollinger bands +1 SD and +2 SD away from mean, the trend is up; therefore, we can define that channel as the "buy zone". Conversely, if price channels within Bollinger bands –1 SD and –2 SD, it is in the "sell zone". Finally, if price meanders between +1 SD band and –1 SD band, it is essentially in a neutral state, and we can say that it's in "no man's land".

One of the other great advantages of Bollinger bands is that they adapt dynamically to price expanding and contracting as volatility increases and decreases. Therefore, the bands naturally widen and narrow in sync with price action, creating a very accurate trending envelope.



A Tool for Trend Traders and Faders
Having established the basic rules for Bollinger band "bands", we can now demonstrate how this technical tool can be used by both trend traders who seek to exploit momentum and fade traders who like to profit from trend exhaustion. Returning back to the AUD/USD chart just above, we can see how trend traders would position long once price entered the "buy zone". They would then be able to stay in trend as the Bollinger band "bands" encapsulate most of the price action of the massive up-move.

What would be a logical stop-out point? The answer is different for each individual trader, but one reasonable possibility would be to close the long trade if the candle turned red and more than 75% of its body were below the "buy zone". Using the 75% rule is obvious since at that point price clearly falls out of trend, but why insist that the candle be red? The reason for the second condition is to prevent the trend trader from being "wiggled out" of a trend by a quick probative move to the downside that snaps back to the "buy zone" at the end of the trading period. Note how in the following chart the trader is able to stay with the move for most of the uptrend, exiting only when price starts to consolidate at the top of the new range.



Bollinger band "bands" can also be a valuable tool for traders who like to exploit trend exhaustion by picking the turn in price. Note, however, that counter-trend trading requires far larger margins of error as trends will often make several attempts at continuation before capitulating.
n the chart below, we see that a fade trader using Bollinger band "bands" will be able to diagnose quickly the first hint of trend weakness. Having seen prices fall out of the trend channel, the fader may decide to make classic use of Bollinger bands by shorting the next tag of the upper Bollinger band. But where to place the stop? Putting it just above the swing high will practically assure the trader of a stop-out as price will often make many probative forays to the top of the range, with buyers trying to extend the trend. Here is where the volatility property of Bollinger bands becomes an enormous benefit to the trader. By measuring the width of the "no man's land" area, which is simply the range of +1 to –1 SD from the mean, the trader can create a quick and very effective projection zone which will prevent him or her from being stopped out on market noise and yet protect his or her capital if trend truly regains its momentum.



Conclusion
As one the most popular technical-analysis indicators, Bollinger bands have become crucial to many technically oriented traders. By extending their functionality through the use of Bollinger band "bands", traders can achieve a greater level of analytical sophistication using this simple and elegant tool for both trending and fading strategies.

With the increasingly widespread availability of electronic trading networks, trading on the currency exchanges is now more accessible than ever. The foreign exchange market, or forex, is notoriously the domain of government central banks and commercial and investment banks, not to mention hedge funds and massive international corporations. At first glance, the presence of such heavyweight entities may appear rather daunting to the individual investor. But the presence of such powerful groups and such a massive international market can also work to the benefit of the individual trader. The forex offers trading 24-hours a day, five days a week, and the daily dollar volume of currencies traded in the currency market exceeds $1.4 trillion, making it the largest and most liquid market in the world.

Trading Opportunities
The sheer number of currencies traded serves to ensure a rather extreme level of volatility on a day-to-day basis. There will always be currencies that are moving rapidly up or down, offering opportunities for profit (and commensurate risk) to astute traders. Yet, like the equity markets, forex offers plenty of instruments to mitigate risk and allows the individual to profit in both rising and falling markets. Forex also allows highly leveraged trading with low margin requirements relative to its equity counterparts. Perhaps best of all, forex charges zero dealing commissions!

Many of the instruments utilized in forex - such as forwards and futures, options, spread betting, contracts for difference and the spot market - will appear similar to those used in the equity markets. Since the instruments on the forex often maintain minimum trade sizes in terms of the base currencies (the spot market, for example, requires a minimum trade size of 100,000 units of the base currency), the use of margin is absolutely essential for the person trading these instruments.

Buying and Selling Currencies
Regarding the specifics of buying and selling on forex, it is important to note that currencies are always priced in pairs. All trades result in the simultaneous purchase of one currency and the sale of another. This necessitates a slightly different mode of thinking than what you might be used to. While trading on the forex, you would execute a trade only at a time when you expect the currency you are buying to increase in value relative to the one you are selling. If the currency you are buying does increase in value, you must sell the other currency back in order to lock in a profit. An open trade (or open position), therefore, is a trade in which a trader has bought or sold a particular currency pair and has not yet sold or bought back the equivalent amount to close the position.

Base and Counter Currencies and Quotes
Currency traders must become familiar also with the way currencies are quoted. The first currency in the pair is considered the base currency; and the second is the counter or quote currency. Most of the time, U.S. dollar is considered the base currency, and quotes are expressed in units of US$1 per counter currency (for example, USD/JPY or USD/CAD). The only exceptions to this convention are quotes in relation to the euro, the pound sterling and the Australian dollar - these three are quoted as dollars per foreign currency.

Forex quotes always include a bid and an ask price. The bid is the price at which the market maker is willing to buy the base currency in exchange for the counter currency. The ask price is the price at which the market maker is willing to sell the base currency in exchange for the counter currency. The difference between the bid and the ask prices is referred to as the spread.

The cost of establishing a position is determined by the spread, and prices are always quoted using five numbers (for example, 134.85), the final digit of which is referred to as a point or a pip. For example, if USD/JPY was quoted with a bid of 134.85 and an ask of 134.90, the five-pip spread is the cost of trading this position. From the very start, therefore, the trader must recover the five-pip cost from his or her profits, necessitating a favorable move in the position in order simply to break even.

More about Margin
Trading in the currency markets requires a trader to think in a slightly different way also about margin. Margin on the forex is not a down payment on a future purchase of equity but a deposit to the trader's account that will cover against any currency-trading losses in the future. A typical currency trading system will allow for a very high degree of leverage in its margin requirements, up to 100:1. The system will automatically calculate the funds necessary for current positions and will check for margin availability before executing any trade.

Rollover
In the spot forex market, trades must be settled within two business days. For example, if a trader sells a certain number of currency units on Wednesday, he or she must deliver an equivalent number of units on Friday. But currency trading systems may allow for a "rollover", with which open positions can be swapped forward to the next settlement date (giving an extension of two additional business days). The interest rate for such a swap is predetermined, and, in fact, these swaps are actually financial instruments that can also be traded on the currency market.

In any spot rollover transaction the difference between the interest rates of the base and counter currencies is reflected as an overnight loan. If the trader holds a long position in the currency with the higher interest rate, he or she would gain on the spot rollover. The amount of such a gain would fluctuate day-to-day according to the precise interest-rate differential between the base and the counter currency. Such rollover rates are quoted in dollars and are shown in the interest column of the forex trading system. Rollovers, however, will not affect traders who never hold a position overnight since the rollover is exclusively a day-to-day phenomenon.

Conclusion
As one can immediately see, trading in forex requires a slightly different way of thinking than the way required by equity markets. Yet, for its extreme liquidity, multitude of opportunities for large profits due to strong trends and high levels of available leverage, the currency market are hard to resist for the advanced trader. With such potential, however, comes significant risk, and traders should quickly establish an intimate familiarity with methods of risk management.

All the very best in your trading endeavors!

The amount of such a gain would fluctuate day-to-day according to the precise interest-rate differential between the base and the counter currency. Such rollover rates are quoted in dollars and are shown in the interest column of the forex trading system. Rollovers, however, will not affect traders who never hold a position overnight since the rollover is exclusively a day-to-day phenomenon.

Conclusion
As one can immediately see, trading in forex requires a slightly different way of thinking than the way required by equity markets. Yet, for its extreme liquidity, multitude of opportunities for large profits due to strong trends and high levels of available leverage, the currency market are hard to resist for the advanced trader. With such potential, however, comes significant risk, and traders should quickly establish an intimate familiarity with methods of risk management.

All the very best in your trading endeavors!

How would you like to make US$1,287 in 10 minutes? Well, if you had purchased a $100,000 lot of US dollar/Japanese yen on Dec 10, 2003 at 107.40 and sold 10 minutes later at 108.80, you could have!

1. Bought $100,000 and sold 10,740,000 yen (100,000*107.40)
2. Ten minutes later, the USD/JPY increases to 108.80
3. Sell $100,000 to buy 10,880,000 yen to realize a gain of 140,000 yen
4. In dollar terms, the gain would be 140,000/108.8 = $1,286.76 USD

So, who was on the other end of the trade taking the huge losses? Believe it or not, it was the central Bank of Japan! And why would they do this? The act is known as an intervention, but before we discover why they do it, let's quickly review the economics of the currency markets.

A Brief Economics Lesson
The entire foreign-exchange market (forex) revolves around currencies and their valuations relative to one another. These valuations play a large role in domestic and global economics. They determine many things, most notably the prices of imports and exports.

Valuation and the Central Banks
In order to understand why interventions occur, we must first establish how currencies are valuated. This can happen in two ways: by the market through supply and demand or by governments (ie: central banks). Subjecting a currency to valuation by the markets is known as floating the currency. Conversely, currency rates set by governments is known as fixing the currency, meaning a country’s currency is pegged to a major world currency (usually the U.S. dollar). Thus, in order for a central bank to maintain or stabilize the local exchange rate, it will implement monetary policy by adjusting interest rates or by buying and selling its own currency on the foreign-exchange market in return for the currency to which it is pegged, called intervention.

Instability and Intervention
Since currencies always trade in pairs (relative to one another), a significant movement in one directly impacts the other. When a country's currency becomes unstable for any reason (speculation, growing deficits, national tragedy, etc), other countries experience the aftereffect. Normally, this occurs over a long period of time, which allows for the market and/or central banks to effectively deal with any revaluation needs.

There becomes a problem, however, when there is a sudden and rapid and sustainable movement in a currency's valuation, which makes it impractical or even impossible for a central bank to immediately respond via interest rates, used to quickly correct the movement. These are times in which interventions take place.

Take the USD/JPY currency pair, for example. Between 2000 and 2003, the Bank of Japan intervened several times to keep the yen valued lower than the dollar as they were afraid of a increase in the value of the yen, making exports relatively more expensive than imports and hindering an economic recovery at that time. In 2001, Japan intervened and spent more than $28 billion to halt the yen from appreciating and in 2002, they spent a record $33 billion to keep the yen down.

Trading & Interventions
Interventions present an interesting opportunity for traders. If there is some significant negative catalyst (such as national debt or tragedy), this can indicate to traders that a currency they are targeting should be fundamentally valued lower. For example, the U.S. budget deficit caused the dollar to fall rapidly in relation to the yen, whose value, in turn, rose rapidly. In such circumstances, traders can speculate on the likelihood of an intervention, which would result in sharp price movements in the short term. This creates an opportunity for traders to profit handsomely by taking a position before the intervention and exiting the position after the effects of the intervention takes place. It is important to realize, however, that trading against a fast-moving trend (looking for an intervention) can be very risky and should be reserved for speculation traders.Furthermore, trading against a trend, especially when leveraged, can be extremely dangerous as large amounts of capital can be lost in short periods of time.

The Intervention
Now, let's take a look at what the intervention looks like on the charts:



Here we can see that between 2000 and 2003, the Bank of Japan intervened several times. Please note that there may have been more or less interventions than shown here since these interventions are not always made public. It is usually easy to spot them when they occur, however, because of the large short-term price movement, such as the one mentioned in the beginning of this article.

Trading
Knowing when interventions may occur is more of an art than a science; but, that doesn't mean there aren't clear indicators to help you. Here are some basic principles to follow:

1. Interventions usually occur around the same price level as previous interventions. In the case of the USD/JPY, this level was 115.00 – notice in the chart above that the interventions pushed the value of the dollar above that point for quite some time. But keep in mind that this may not always be true; interventions may cease if the central bank deems it unnecessary (i.e. too costly). This is also apparent where we see the value drop below 115.00.
2. Sometimes there are verbal clues prior to interventions. Japan’s former finance minister Kiichi Miyazawa was infamous for threatening to intervene on multiple occasions. Similarly, the European Union has given clues as to their possible intervention in the future. Sometimes these words alone are enough to move the markets. Keep in mind, however, that the more often traders hear these threats with no action, the less impact these threats will have on the market.
3. Analysts also often give good estimates of intervention levels. Keep an eye on foreign exchange analysts from popular banks and investment firms for a good idea of when to expect them.

Knowing these can help you determine when an intervention is likely to occur. Here is some advice for trading when an intervention is occurring:

1. Gauge the expected price levels by locating previous intervention movements. Again, we can see that most of the major interventions in the USD/JPY pair amounted to 125.00 or so, before resuming a downward course again.
2. Always keep a stop-loss point and a take-profit point to lock in gains, and limit losses. Make sure to set your stop-loss at a reasonable level, but leave enough room for the downside before an intervention occurs. Take-profit points should be set at levels previously attained by interventions.
3. Use as little margin as possible. Although this lowers you potential profit, it also reduces the risk of getting a margin call. And, since you are trading against the long-term trend, margin calls become a significant risk if an intervention doesn't occur during the time you plan.


Conclusion
Interventions occur as a result of central banks intervening by using their reserves in order to stabilize the value of their currency. Although they can be extremely profitable, trading them is mostly for speculators. There are several ways to try and gauge when an intervention is likely to occur, but it is always a good idea to be prepared by using low (if any) leverage, and smart money management (stop-loss/take-profit). All in all, they present an interesting opportunity for any forex traders looking for ideas to profit.
