The main concern of this study is to propose high order multistep collocation
method for evaluating the numerical solution of stochastic fractional integro-differential
equations. For this purpose the unknown function is approximated by Hermit interpolation
and its Caputo fractional derivatives are calculated and substituted in main equation. Also
using some concepts of financial mathematics, It’o integral in main problem transform to
classic Stieltjes integral. Then utilizing multistep collocation method, obtained equation
reduces to some algebraic system. Illustrative examples are given for showing the
efficiency and accuracy of the method.
