Investment analysis—Mathematical models, I. Wiley trading advantage. C34 Triptych 2. Although the book was in French, which spoke as a child but alas do not speak now, I was able to understand the basic principles he espoused through a careful perusal of the illustrations and the bit of the text I could puzzle out.
One of the great joys of having invented an analytical technique such as Bollinger bands is seeing what other people do with it. A broad range of techniques and strategies are covered, supported by charts that clarify the text.
Concepts such as bubbles and parallels will be familiar to anybody who has looked at Bollinger bands with any degree of curiosity. However, some of their implications regarding trends may be eye- openers for many.
Few have understood the forecasting implications of changing volatility, though Bollinger bands make this aspect of the evolution of the price structure clearly evident. By drawing a distinc- tion between sustainable and unsustainable moves, Mr Cahen draws attention to this important aspect of the price structure. This is the area in which I have done most of my work and it is a great pleasure to see another analyst demonstrate the power of this approach.
Especially interesting is his use of the band structure to determine which indicators to base decisions on. He uses the classical technical analysis framework, days, weeks and months, allowing one period to inform another in his triptych. I have long advocated the use of short-, intermediate- and long-term time frames, and it is gratifying to see those ideas deployed successfully here. Recently I had the pleasure of speaking with Mr Cahen in Paris at a one-day seminar sponsored by Waldata.
I had a chance to learn of the latest developments and twists in his work, I found them very inter- esting and in at least one case quite challenging. I hope that reading this book will make you think — after all, what more could you ask? One of these offers a means of forecasting trend reversals, which shows an impressive success rate when large-scale swings are taking place in prices or indices. This means that the method now gives even more accurate forecasts, whether for intraday trades or when trading out to several days or weeks ahead.
Acknowledgements By encouraging analysts to integrate volatility — a variable that has become critical — into forecasting models, John Bollinger deserves the grateful thanks of technical analysts the world over. Bollinger bands and their applications have helped technical analysis to evolve, to become a permanent fixture of the financial landscape, and to achieve credibility as we move into the new millennium.
Purists will, of course, point to erroneous usage from a statistical standpoint, and can easily back up their claims. Let us, however, be pragmatic, and look once again at the merits of the model and the approach. Traders who use Bollinger bands regularly make significant capital gains. This was the target John Bollinger set himself, and he has achieved his goal.
Yet his model goes further, because when sharp swings in stock prices are observed, Bollinger bands are the simplest and most effective means for investors to retain control over the situation. These changes are not related to the business cycle, but are genuinely structural changes. Without detracting from his achievement, I am joining forces with him in hoping that others will also use his research and ensure that it remains familiar to all investors who use technical analysis models for many years to come.
Special thanks also to Esther M. All the graphs prepared for this book were computer-generated using Walmaster Gold software Waldata, Immeuble le Vivaldi, 87 route de Grigny, Ris-Orangis, France; tel. It will help investors to judge the best moment to take up or unwind a market position, and to compare the fluctuation potential of several securities or markets thanks to a single unit of measure used across the com- plete spectrum of financial products — futures contracts, stock indices, domestic or international securities, currencies, commod- ities, and so on.
Speculators, on the other hand, will find a structured system they can use to take up positions only when strong price fluctuations are expected, in time frames of anything from ten minutes to several weeks.
At present and for the foreseeable future , it is will be essential to take large-scale volatility into account as well as drastic changes in its nature and direction, together with the possibility that markets can become seriously agi- tated after a period of calm, and vice versa. Observing patterns from a static viewpoint offers only a partial vision of the market. This is one of the causes of the impasse in which mainstream technical analysis finds itself, and is partly due to the very limited technical resources at the disposal of analysts and the fact that their methods have changed little since With advances in information technology since , researchers have been able to develop new concepts.
Thus, by taking the behaviour of various categories of trader simultaneously into account, the indicators can be analysed from a dynamic angle, exploring changes in the state of the indicators themselves, and changes to them along a time line.
We intend to leverage these concepts to make forecasts andjimbue them with a reliability and lifespan that no traditional method can equal. After all, why use the value of these indicators at a given point in time to underpin our forecasts? It could be justified in terms of improving communication if their value remained constant.
But what interests operators is to find out where the markets are heading when prices start trending. In this case, the values assigned by the analyst only hold true at the time when the analysis is made. In Figure 1. Between points 2 and 3, the value of the indicator was stable. The target i. However, on the right-hand curve, we note a sharp uptrend.
If indicator 4 is not used as a support level, the drop will accelerate. Traders thus take up a buy position at point 5 es through the indicator. At point 6, the value at which the trader must abandon his position is no longer the support breakthrough value calculated at point 5, If the trader and unwind it if the price cros: Introduction 3 fa7s oso avr mai juin jul mars am.
Calculating targets in stable and trending markets. The use of the numerical value leads the trader into a very serious trading error because he has not used his model to unwind the position, otherwise he would have applied the indicator value at point 6 and turned a profit.
Retaining the value computed at point 5 as a forecast is no different from picking a number at random. All the trader has is an observation of what has happened at points 2 and 5. So when there is a marked market trend, the stronger the trend, the more mistaken the numerical forecasts. To get round this problem, we recommend setting the indicators themselves as objectives. F, will thus be at cally updated as prices change. In a specific sector, the various values will all intersect a given indicator at the same time.
Elf, for example, will cross a particular threshold at the same time as Total and the per- barrel oil price. This principle is also used to strengthen risk manage- ment, 1. States of a Market When we observe the historical series of prices representing market fluctuations, we see two possible states: stabl nding. The trend is either an uptrend or a downtrend.
This is always represented on the price chart. In the left-hand section of Figure 1. There is no trend. In the centre, the moving average at point 2 is moving upwards, revealing an uptrend; while on the right, the moving average at point 3 is on a downtrend. When the market is stable, traders will rely more on an indicator. Any trader, whether a professional or an indivi- Redes, will thus sooner or later be confronted with a market showing a strong or very strong trend.
These are subjective observations, so you will consequently have to calibrate each market. Target Indicators The two indicators used are of the moving average type. By using different triptychs, you can identify the objectives best suited to individual users. One of these indicators does, however, have another capital function: it allows you to determine the future state of the markets, and hence shows you which indicators to concentrate on.
The period moving average we have been using up to now as an indicator is a component of one of these two indicators I will now proceed to analyse. What is more, when the markets are trending strongly, target indicators become benchmark indicators in order to forecast market changes, whether the trader is an investor or a speculator. These indicators, the parabolic and the Bollinger bands, are also used by speculators to take, manage and generally unwind their positions.
Parabolic The parabolic is a very popular tool among currency traders. Generally used as a trend-change indicator in volatile markets, it also provides information when fluctuations are in a narrow range.
Welles Wilder Jr, Trend Research, Standard parameters The standard parameters are always applied. Calibration Differences in the value of the parabolic from one system to another and on the same unit of time are due to the length of the historical series used. The right-hand part shows the parabolic in a weakly trending market.
Optimization None. Reading the parabolic When the parabolic is above the price line, the market is bearish.
When below, it is bullish. During a given period, prices touching or crossing the parabolic signal a trend change. The shape of the curve formed by a succession of values also provides information. You can draw a straight line from the first two points.
