I have used statistical models of volatility to improve execution prices.

It doesn’t require very advanced modeling to estimate a probability of e.g. getting filled at midprice (saving half the bid/ask spread) within a short time period.

Just basic Bayesian with a look-back window.

Execution cost is a big topic in the trading industry.

Love it, such a straightforward formulation.

Can you elaborate how did you do that?
