Research in both economics and psychology suggests that, when agents predict the next value of a random series, they frequently exhibit two types of biases, which are called the gamblerâ€™s fallacy (GF) and the hot hand fallacy. The gamblerâ€™s fallacy is to expect a negative correlation in a process which is in fact random. The hot hands fallacy is more or less the opposite of this â€“ to believe that another heads is more likely after a run of heads. The evidence for these fallacies comes largely from situations where they are not punished (lotteries, casinos and laboratory experiments with random returns). In many real-world situations, such as in financial markets, succumbing to fallacies is costly, which gives an incentive to overcome them. The present study is based on high-frequency data from a market-maker in the foreign exchange market. Trading behaviour is only partly explained by the rational exploitation of past patterns in the data, but there is also evidence of the gamblerâ€™s fallacy: a tendency to sell the dollar after it has risen persistently or strongly.
