I have heard that ITG, LiquidMetrix, MarkIT and TradingScreen has good Transaction Cost Analysis (TCA) research. I wonder which firm one would choose to have an impact model formula inside his simulations (that is to optimize traded portfolio size).
There are two ways to achive this:
- find a firm which discloses their complete impact model
- find a firm which provides a detailed simulator including the impact models
Open for suggestions for both options.
