The virtual price impact function

In my presentation I will show one of the main differences between the empirical and virtual price impact functions, namely that time-series analysis can be carried out more easily on virtual price impact functions, since it can be estimated for short time-periods – e.g. for one second. I will point out in my presentation, that knowing the time-variation of the price impact function is important for the market participants, in order to be able to predict the price impact of trades in the future, and to estimate the additional trading costs related to the price impact, and also to be able to build an optimal trading algorithm based on the price impact function.
