Using a standard chartered bank malaysia foreign exchange rates limit-order-book market, we develop a simple framework to model the dynamics of supply/demand and its impact on execution cost. Dynamic Trading Strategies and Portfolio Choice). We also show that the predictions about the optimal trading behavior can have interesting implications on the observed behavior of intraday volume, volatility and prices.

Attention is paid to consequences of estimating auto-covariance matrices from small finite samples, and auto-covariance matrix cleaning strategies to mitigate against these are investigated. We introduce a random delay parameter, which defers limit order execution and characterizes market liquidity. Abstract, we study the optimal execution strategy of selling a security. The distribution of expected time-to-fill of limit orders conforms to the empirically observed exponential distribution of trading times, and its variance decreases with liquidity.

Previous studies on the optimal trading strategy to execute a given order focuses mostly on the static properties of the supply/demand. In this paper, we show that the dynamics of the supply/demand is of critical importance to the optimal execution strategy, especially when trading times are endogenously chosen. Nber Working Paper.

The cost savings from the optimal strategy over the simple continuous strategy can be substantial.

We obtain a closed-form solution and demonstrate that the presence of the lag factor linearizes the impact of other market parameters on the optimal limit price. Abstract: Motivated by recent advances in the spectral theory of auto-covariance matrices, we are led to revisit a reformulation of Markowitz' mean-variance portfolio optimization approach in the time domain. Finally we apply our framework to real world data. We show that the optimal execution strategy involves both discrete and continuous trades, not only continuous trades as previous work suggested. In a continuous time diffusion framework, a risk-averse trader faces the choice of selling the security promptly or placing a limit order and hence delaying the transaction in order to sell at a more favorable price.
