We develop a simple model of the exchange rate in which agents optimize their portfolio and use different forecasting rules. They check the profitability of these rules ex post and select the more profitable one. This model produces two kinds of equilibria, a fundamental and a bubble one. In a...

Over the last decade, the microstructure approach to exchange rates has become very popular. The underlying idea of this approach is that the order flows at different levels of aggregation contain valuable information to explain exchange rate movements. The bulk of empirical literature has...

This paper examines the mutually reinforcing interactions between exchange rate dynamics and technical trading strategies. I first show that technical trading systems have been quite profitable during the floating rate period. This profitability stems from the successful exploitation of...

The study analyses the interaction between the trading behaviour of 1,024 moving average and momentum models and the fluctuations of the yen/dollar exchange rate. The paper shows first that these models would have exploited exchange rate trends quite profitably between 1976 and 1999, and then...

The paper investigates the profitability of 1,024 moving average and momentum models and their components in the yen-dollar market. It turns out that all models would have been profitable between 1976 and 2007. The models produce more single losses than single profits. At the same time, the size...

I show first that these models would have exploited exchange rate trends quite profitably between 1976 and 2007. I then show that the...

Since 1997, the Bank of England Monetary Policy Committee (MPC) has met monthly to set the UK policy interest rate. We examine evidence of systematic patterns in exchange rate movements on MPC days over the first decade of operation of the MPC. Daily data reveal significant differences in...

This paper sheds new light on a long-standing puzzle in the international finance literature, namely, that exchange rate expectations appear inaccurate and even irrational. We find for a comprehensive dataset that individual forecasters' performance is skill-based. 'Superior' forecasters show...

This paper analyzes the relationship between currency price changes and their expectations. Currency price change expectations are derived with the help of different order flow measures, from the trading behavior of investors on OANDA FXTrade, which is an internet trading platform in the foreign...
