We propose a general form of vector Multiplicative Error Model (MEM) for the dynamics of duration, volume and price … the market. But we highlight that it is unexpected component of trading duration or trading volume that carry the …

The main goal of this paper is to gain insights into the dependence structure between the duration and trading volume … distribution) can be replaced by a logarithmic specification with more-flexible conditional distributions. The price duration and … trading volume associated with this duration exhibit dependence in the tails of distribution. We may conclude that high …
