Hi there. In the chapter of binomial model (pg.8), "Note, by convention E_Q[Y|F_0] is sometimes rotten as E_Q[Y}" I would like to know what is Y and F_0 here. Thanks in advance.
F₀ is the filtration of the risk-neutral process i.e. information set generated by history of stock price movements up to and including time zero Y is the derivative value, stock price or any other process which may be dependent on past information
