Higher orders can be conceived. The bar has an open, close, low and high levels of price. In the liquid market like forex, close, low and high should be sufficient while open is typically not too different from the previous close and is believed to be redundant. To judge the quality of market predictions, we are interested in multivariate cumulants, since for each of the three essential components of a candle there is a prediction.
Because we make predictions for each of these components, the number of variables we would like to correlate is even, and therefore we are interested in even-order cumulants. Take for example the daily candle. We can generate predictions for daily changes in low and high, such that the correlation between the real and predicted change for high will be positive. Same for low. Here we use the notation: E[x 1 x 2 …] gets replaced by E[1,2…] for the sake of brevity.
What is being subtracted is in fact products of lower order cumulants, which in turn subtract their lower order cumulants, which is why there are terms with both plus and minus sign alternating in a certain order. A recurrence relation exists allowing one to express higher order cumulants in terms of lower order ones. A cumulant of order higher than 2 will go to zero if any two quantities are proportional to each other:.
The fact that it will also go to zero whenever any one quantity is statistically independent of the rest, combined with the additivity of cumulants, implies that a higher order cumulant will go to zero whenever any pair of quantities has even a less deterministic, randomized form of that equation:.
A non-zero higher order cumulant indicates that a relationship between the data is not merely Eq. To keep the cumulant independent of the units in which the underlying quantities are expressed, we sometimes normalize it:.
The intention of this post is to tie together several topics which appeared on my radar screen in the course of the trading system optimization. First, it has been understandably hard to fully rid oneself of vestiges of the mainstream financial theory based on the postulate of market efficiency, while building a wealth-generating tool relying explicitly on demonstrable market inefficiencies. Then came the understanding of the fact that an arithmetic average of returns gives one a biased picture of long-term return , and consequently, Sharpe ratio is built around biased quantities.
In what followed, the key concept was that of Kelly Criterion and the rich intellectual context it is part of — quite remote from the mainstream financial engineering. Initially I came across a mention of Kelly Criterion in some pieces by Edward Thorp, found on his website , but did not fully appreciate the depth of the context.
The work introduces the concept of information in the strict theoretical sense. It deals with measures of information and redundancy. These are probably two most important concepts in the algorithmic trading — suffice it to say that if the markets had not been redundant, algorithmic trading in the sense discussed and developed here would have been impossible and trading would degenerate into gambling.
Much of ForexAutomaton. Shannon introduced the concept of mutual information to characterize transmission capacity of communication channels. The communication channel considered is a very specific one: it is a noisy channel allowing a gambler to know in advance the outcomes of chance events and bet accordingly. Because the chance of losing is non-negligible, the gambler can not bet all of her capital on every game, but because the value of insider data she receives is non-negligible either, her optimal betting ratio is non-zero.
The optimal betting ratio in the simple case of two symmetric outcomes equals the difference between the win and loss probabilities if the tip is followed. This gets me back to the measurements of Forex Automaton prediction quality — the state of the art at the moment is the measurement of Pearson correlation coefficient between predicted and real value of logarithmic returns.
Where does this all leave the common theory with its Sharpe ratios and efficient portfolios? A recent June article by Javier Estrada, Geometric Mean Maximization: an Overlooked Portfolio Approach? proved informative to me. Estrada contrasts Sharpe ratio maximization which leaves one with not one, but an entire efficient frontier of portfolios with geometric mean maximization Kelly by other name leading to the largest expected terminal wealth.
Estrada notes that SRM Sharpe ratio maximization is a one-period framework, while GMM geometric mean maximization is a multi-period framework — I take this to mean that the biased nature of Sharpe when cumulative returns are concerned as already noted, one of my early disappointments with this statistic is thus acknowledged in the academic community. Why do the practitioners overlook a useful criterion? One should never underestimate the role of the overall surrounding cultural and ideological context in the development of science.
This is because Kelly addresses the problem of the value of information directly, it is at the heart of his approach.
When evaluating the performance of a trading system, I calculate the first moment an arithmetic mean of the series of returns as well as the second one a variance of the series. The series of returns would be composed of annualized returns calculated every month. However there is a subtlety. If {r 1 ,r 2 ,r 3 ,… r n } is a series of monthly returns for some period ratios of capital at the end of the period to that at the start of the period , then the total return for the same period will be the product r 1 r 2 r 3 … r n.
This operation is known as taking the geometric mean. Arithmetic mean is always greater than or equal to the geometric mean. This fact is well known from university math courses. For example, if the series of returns is 1.
In this particular example, the arithmetic average of returns will tell you that you are making money whereas in fact you are losing. Arithmetic mean equals the geometric mean in the particular case when all elements of the series are equal. The more volatility there is in the series, the more difference between the two means can be expected.
The bottom line is that the results of the research so far should be revisited using the simple return and the Sharpe ratio based on such return instead of the first moment of the series of annualized returns. The first moment gives a biased estimate of the actual return. Nevertheless, since the main driving logic in the choice of parameters was minimization of the drawdown, the basic conclusions regarding the parameter choices are likely to stay the same.
Operations not meeting these requirements are speculative. I continue with the logarithmic returns technique that proved useful in forex. Like the previous reports, this document begins with historical LIBOR charts for the Swiss Franc, continues with volatility analysis, and culminates with autocorrelations and correlations.
You will see that predictable patterns in CHF LIBORs vary with duration term. Autocorrelations of short-term LIBORs show fast about 4-day period oscillation. For 3-month and 6-month terms, the main correlation pattern does not develop day period waves on top of positive background, in contrast to USD and EUR LIBORs, but keeps oscillating between positive and negative autocorrelation values, with the oscillation period longer than that of the shorter terms.
The autocorrelation of month LIBOR remains similar to 6-month instead of becoming more uniformly positive as it does for JPY or more jittery as it does for USD, EUR and GBP.
Time axis is labeled in MM-YY format. Their history looks more like a dumb version of the shorter ranges.
For the short maturities, the markets jump the gun trying to anticipate the course of events almost regularly, to the extent this nervousness must represent a regular and significant speculative opportunity, if the market instruments tied to the LIBOR rates have the same features.
This will be seen qunatitatively in the correlation plots. Table 1: Day-by-day volatilities RMS for the time series of logarithmic returns in CHF LIBOR in , various maturities. Volatility of CHF LIBOR seems to go down with duration in a more reliable fashion than for other currencies, in particular, USD and EUR.
Volatility is a measure of the width of the return distribution. The distribution of logarithmic returns look broader than power-law. Remember that with returns already containing logarithm and with the vertical axis explicitly logarithmic, we are looking at what is effectively a log-log plot, where any power law dependence would have looked linear, with different power law exponents resulting in different slopes.
Continuing with the psychiatric analogy, these indicate rapid next day or two, depending on LIBOR term changes in the mood of the credit market, a price action followed by an immediate correction. The noise is obtained from martingale simulations based on the historical volatilities of LIBOR for the period under study. The noise is presented as mean plus-minus 1 RMS, where RMS characterizes the distribution of the correlation value obtained for each particular time lag bin by analyzing 20 independent simulated uncorrelated time series.

Currency pair correlation is an essential concept that can help make your trading activities in the foreign exchange forex market more successful. However, the concept requires a thorough understanding in order to determine the right time to enter and exit the market as well as the right strategies to employ.
Currency correlation basically refers to the relationship of two separate forex pairs. A positive correlation means that the two forex pairs move in sync in the same direction while a negative correlation means that the pairs move in opposite directions. While it may sound easy to trade and gain profits in the forex market based on correlations, you could also double your losses if your forecasts are wrong or if your hedging strategies are ineffective. Correlation coefficient is a numerical range that measures the strength of correlation between two forex pairs.
It ranges from 1. This generally uses the Pearson correlation coefficient formula. Most traders also use this equation in calculating and creating their forex correlation analysis on computer spreadsheets. Bear in mind that the forex correlation strength depends on a variety of factors including the time of day when the market opens in both countries and the trading volume in the markets of both currencies. This also means that the values differ when calculating the forex correlation strength on a monthly, quarterly, bi-annual and annual basis.
monthly, semi-annual and annual. Some trading companies provide daily data that traders can use to create their custom correlation table on computer spreadsheets.
Alternatively, you can use forex auto trading software to avoid the hassle of manually formatting your correlation table. An automated trading system basically keeps track of forex trends and timely sends notification to inform you of lucrative opportunities. Examples of forex pairs that typically have positive correlation are:. In this way, you diversify your portfolio while maintaining a core direction in your trades as well as manage your risks to as low as possible.
