You'd need to define the "topic".

The topic of the Value in Time book is to try to better understand and measure market activity. This is a vast definition that can be applied to 95% of the trading books. However, my stand in Value in Time was to uncover hidden activity with large players.

I believe that there are many traders/firms that have developed tools to unveil hidden activity. For example in analyzing transactions around earnings dates, by statistically evaluating options activity, by analysing the largest funds' positions in different stocks/sectors, but combing through hedging activity, by measuring the demand/supply through millisecond order spoofing, etc...

There is no limit to what competitors will achieve to gain a market advantage and most of it will not be written in books, except after the techniques have become useless.

Why would somebody write something in a book that has offered a trading advantage.
Only a naive guy like me will write a book.
