Australian Dollar/US Dollar and Swiss Franc/Japanese Yen are weakly correlated currency pairs. For the period under study, the correlation is limited to the 1-hour wide 0 time-lag bin and therefore offers little value to the forecaster. In this regard, this pair of exchange rates resembles AUD/USD and GBP/JPY.
AUD/USD and CHF/JPY are weakly correlated on average for the period. Looking at the 0-hour time lag, which is what the table represents, the correlation is the least pronounced in the American session, most pronounced in the European session.
Fig.1:Cross-correlation of AUD/USD and CHF/JPY, derived from the hour-by-hour logarithmic returns, for the three trading sessions. Time frames of the sessions are shown in New York time. The fact that most of the correlation is concentrated at the 0 lag means that the correlation (reported in the table) works out mostly on the time scale of up to 1 hour. For the purpose of trading system development, correlations with non-zero time lag would be of particular importance. It is these correlations that allow us to make forecasts. Alas, Fig.1 and Fig.2 (European session compared with martingale noise) present no indication of such correlations for this currency pair combination, given the level of uncertainty represented by the red band.
Fig.2:Cross-correlation of AUD/USD and CHF/JPY for the European (Eurasian) trading session shown against the backdrop of statistical noise (red). The noise is obtained from martingale simulations based on the recorded volatilities of AUD/USD and CHF/JPY in this trading session 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 bin by analyzing 20 independent simulated pairs of uncorrelated time series. The data used are from the period 2002-08-20 00:00:00 to 2008-02-01 00:00:00. Bookmark with:

"I noticed that in advances as well as declines... prices were apt to show certain habits, so to speak. There was no end of parallel cases and these made precedents to guide me. I was only fourteen, but after I had taken hundreds of observations in my mind I found myself testing their accuracy, comparing the behaviour of stocks to-day with other days. It was not long before I was anticipating movements in prices. My only guide, as I say, was their past performances. I carried the "dope sheets" in my mind. I looked for... prices to run on form. I had "clocked" them. You know what I mean... Another lesson I learned early is that there is nothing new in Wall Street. There can't be because speculation is as old as the hills. Whatever happens in the... market to-day has happened before and will happen again."
-- from Reminiscences of a Stock Operator, a classic by Edwin Lefèvre, inspired by the biography of a legendary trader Jesse Livermore, an author himself, who made and lost fortunes, was like catnip to women and commited suicide at an age of 63.
"...I hope to prove that traditional approaches such as the economic indicator approach do not work. No consistent correlation exists between the U.S. dollar and U.S. economic indicators, but conventional wisdom says that the two move in lockstep. Why is this approach followed so fervently if its foundation is rooted in falsities? The reason that markets move in identifiable patterns is probably the same reason that many accept as gospel the conventional approaches to market analysis and trading that have marginally successful track records at best. That reason is the propensity for humans to follow the crowd, especially in situations as emotionally driven as trading. ...I think that I can share with you a better (and cheaper) approach to analyzing and trading the FX market, an approach that will give you an edge, if only because you are not following the crowd." -- Jamie Saettele, Sentiment in the Forex Market.
