DislikedYou invaded this thread with the bold claim that one could trade a random walk.
Extraordinary claims like this need extraordinary proof.
Instead you come up with the "volatility pumping" example which has nothing to do with trading random walks at all, it is about trading a portfolio of stocks which are not random walks at all, and a flawed excel sheet which also does not implement a random walk as it has become clear after analyzing it.
All arguments were already given in this thread. Simply scroll back and try to understand them....Ignored
Sorry to have to say this, but you may benefit from hearing it:
Your thinking is at the level of a half-educated person, and your manners are at the level of an uneducated person.
Goodbye.
