In stock market, foreign currency exchange market, or any other asset trading system, there are high-density data, which is a typical data streams. And the trading rules are often the functions of many variables. The visualization of these systems is very important for users to do analysis and trading. So the problem is how to show the graph of the large data and multiple-variable functions. Th...

The study contrasts mainstream economics – operating on time scales of hours and days – with behavioural finance, econophysics and high-frequency trading, more applicable to short-term time scales of the order of minutes and seconds. We show how the central theoretical assumption underpinning prevailing economic theories is violated on small time scales. We also demonstrate how an alternative b...

One is the Hang Seng index in Hong Kong markets. The other is a portfolio of indexes from six major markets in the world. Being different from the study on foreign exchange rates [5], we find that in generating the tradi...

In this paper we study the problem of predicting the daily foreign exchange rate (FX) between the US Dollar and the German Mark. The study can be seen as a typical example of predicting noisy time series. Our approach based on neural networks consists of searching for the optimal representation of the underlying market by selecting the optimal training patterns. Moreover we develop a trading sy...

In this paper, we develop and test a theoretical model of multi-market trading to explain the differences in the foreign share of trading volume of internationally cross-listed stocks. The model derives an equilibrium which predicts that, under fairly general conditions, the distribution of trading volume across exchanges competing for order flow is related to the correlation of the cross-liste...

This paper studies the interaction between dealer markets and a relatively new form of exchange, passive crossing networks, where buyers and sellers trade directly with one another. We find that the crossing network is characterized by both positive ~“liquidity”! and negative ~“crowding”! externalities, and we analyze the effects of its introduction on the dealer market. Traders who use the dea...
