I had Harris in his Trading and Exchanges class 531 at USC. I have his text book when they were merely lecture notes in my library. Great guyâ¦great class.
We spent most of the semester on the true cost trading and execution....and which types of traders ultimately pay for the livelihood of others.
Though, replicating his calc based proofs absolutely sucked.

Quote from profturf:
Mr Larry Harris magnificent book, Trading and Exchanges has a related extension of this idea wherein he divided traders into ephemeral traders and economic traders, and shows that the former, and their followers are destined to pay the frictional upkeep of the latter.
Nice
