报告摘要:

We provide a review on quantitative methods forlow-medium frequency trading and high frequency trading. For low-mediumfrequency trading, we review the different econometric estimators to extract atrend of a time series which is widely used in momentum strategies. Wedistinguish between linear and nonlinear models as well as univariate andmultivariate filtering. For high frequency trading, we introduce a multivariatepoint process describing the dynamics of the Bid and Ask price ofa financial asset. The point process is similar to a Hawkes process, withadditional constraints on its intensity corresponding to the naturalordering of the best Bid and Ask prices. We study this process in thespecial case where the fertility function is exponential so that the process isentirely described by an underlying Markov chain including the constraintvariable. Natural, explicit conditions on the parameters are establishedthat ensure the ergodicity of the chain. Moreover, scaling limitsare derived for the integrated point process.

此报告主要基于两篇文章:“ Trend Filtering Methods For Momentum Strategies” 和 “Modelling Bid and Ask Prices Using Constrained HawkesProcesses: Ergodicity and Scaling Limit”。
