Query: Market Microstructure Knowledge Needed for Controlling an Intra-Day
  Trading Process   A great deal of academic and theoretical work has been dedicated to optimal
liquidation of large orders these last twenty years. The optimal split of an
order through time (`optimal trade scheduling') and space (`smart order
routing') is of high interest \rred{to} practitioners because of the increasing
complexity of the market micro structure because of the evolution recently of
regulations and liquidity worldwide. This paper translates into quantitative
terms these regulatory issues and, more broadly, current market design. It
relates the recent advances in optimal trading, order-book simulation and
optimal liquidity to the reality of trading in an emerging global network of
liquidity.
