It is shown in this letter that the magnitude of exchange rate overshooting is larger than in Dornbusch (1976) when chartists are introduced into the model. Also, the extent of overshooting depends inversely on the planning horizon. The latter follows from explicitly modelling the empirical observation that, for shorter planning horizons, more weight is placed on technical analysis, while more weight is placed on fundamental analysis for longer planning horizons.
This paper tested two of the simplest and most popular trading rules – Auto-Regressive Models and Moving Averages – by utilising the Australian Dollar relative to US Dollar from 1 Jan 1986 to 9 June 1999. This data set was used by Tan [1995, 1997] in his study in comparing the profitability of systems based on Artificial Neural Networks and ARIMA models.
We investigate the informative property of quoting activity, measured by the frequency of price revisions, in the Euro/Dollar foreign exchange market. We use the multivariate double autoregressive conditional Poisson model, designed for time series of count data.
Ce papier étudie la sensibilité de la prédictibilité et de la profitabilité des figures chartistes aux fréquences d’observations, types de cours et à la nature des méthodes de détection. Les différentes figures étudiées présentent un pouvoir prédictif supérieur à 50% et l’adoption des règles de trading sousjacentes aux figures génère des profits significatifs.
