Trading Volume, Illiquidity and Commonalities in FX Markets

Trading Volume in Dealer Markets ∗

We develop a financial market trading model in the tradition of Glosten and Milgrom (1985) that allows us to incorporate non-trivial volume. We observe that in this model price volatility is positively related to the trading volume and to the absolute value of the net order flow, i.e. the order imbalance. Moreover, higher volume leads to higher order imbalances. These findings are consistent wi...

Trading volumes, volatility and spreads in FX markets: evidence from emerging market countries

This paper provides empirical evidence on the relationship between trading volumes, volatility and bidask spreads in foreign exchange markets. It uses a new data set that includes daily data on trading volumes for the dollar exchange rates of seven currencies from emerging market countries. The sample period is 1 January 1998 to 30 June 1999. The results are broadly consistent with the findings...

We use a class of stochastic volatility models with multiple latent factors to investigate the joint dynamics of return, trading volume, and open interest (a proxy for market depth) in currency futures markets. In accordance with theory, the empirical evidence indicates that there is more than one latent factor affecting these three variables. However, the evidence is ambivalent on the choice b...

The latter depends on the availability of private information that is stochastically changing over time. In equilibrium, traders estimate the availability of private information using past periods’ trading volume and use this information to adjust their strategies. The time-s...
