For the DM option the time differentiated discounting ( R and r ) results in an apparent shift of the projected value outcome distribution, S ~ {\displaystyle {\tilde {S}}} , relative to the X ~ {\displaystyle {\tilde {X}}} , or the scalar mean X ...
For Asian options, the payoff is determined by the average underlying price over some pre-set period of time. This is different from the case of the usual European option and American option , where the payoff of the option contract depends on the price of the underlying instrument at exercise; Asian options are thus one of the basic forms of ...

The tree of prices is produced by working forward from valuation date to expiration. At each step, it is assumed that the underlying instrument will move up or down by a specific factor ( u {\displaystyle u} or d {\displaystyle d} ) per step of the tree (where, by definition, u ≥ 1 {\displaystyle u\geq 1} and 0 < d ≤ 1 {\displaystyle 0<d ...
