Fig. 2From: Foreign exchange trading and management with the stochastic dual dynamic programming methodScenario structure for price movements when \(T = 5\). (Left): General scenario tree. The number of states (nodes) is equal to \(\frac{{2^{5} - 1}}{2 - 1} = 31\). (Right): Lattice. The number of states (nodes) is equal to \(\mathop \sum \limits_{k = 1}^{5} k = 15\)Back to article page
