ok so its weird because i read all three of these books in 2007-2008 and my lasting influence was to change how i measure “time”. theta time, variance time, volume time etc (the latter not being viable post HFT)

maybe its because i am a dumb when it comes to fancy math (me no like greek letters, me like long descriptive variable names and code) but hey, books are what we get out of them in the long run.
