Using Historical Market Data to Denoise Order Slippage

The level of data that you need to sort of prove out, let's say a parent order slippage statistics for day long orders or multi day orders is humongous. So because of the noise, it's very hard to say anything like that. We don't expect that's a problem unique to us. That's probably a problem that even many biocide firms, if they aggregate all their data over brokers, still don't necessarily have enough data to say something definitive about that.
