Review of "On a fundamental statistical edge principle"

The manuscript "On a fundamental statistical edge principle" provides a significant contribution 
to the field of quantitative finance by presenting a thorough theoretical framework for enhancing 
trading strategies through the use of self-generated historical trading information (HTI). The 
authors argue convincingly that leveraging HTI is a necessary condition for establishing a 
statistical edge in trading practices.

The introduction lays a strong foundation by establishing the importance of HTI in constructing 
profitable trading strategies and setting the stage for the ensuing discussions. The paper 
proceeds to establish a theoretical basis for why any trading strategy that does not use its own 
HTI is inherently suboptimal, and how a strategy that does exploit HTI can consistently outperform it.

Moreover, the paper does well to address the real-world implications of the proposed principles, 
suggesting how these can be applied in actual trading scenarios and highlighting the potential 
for developing more sophisticated trading strategies that are in tune with the mechanics of 
financial instruments.

The authors have clearly identified the relevance of their research by not only focusing on the 
theoretical model but also discussing its practical applications in the real world and future lines 
of research, thus presenting a comprehensive view of its utility.

While the paper is impressive in its current form, its practical applicability could be further 
enhanced by including performance analysis or results from paper trading, as well as a 
thorough estimation of transactional costs such as turnover. These additions would provide 
practitioners with a more tangible demonstration of the strategy's efficacy and potential for 
implementation in a live market environment.

In conclusion, the paper is a commendable effort that lays down a theoretical foundation for 
exploiting historical trading information to achieve a statistical edge. It successfully bridges the 
gap between theoretical models and practical trading strategies, making it a valuable read for 
both academics and practitioners in the field of finance. I am impressed by the research 
contribution and recommend its publication.
