This research investigates the time fractional Ivancevic option pricing model and presents two distinct solution methods: the invariant subspace method for obtaining exact solutions and the residual power series method for generating approximate solutions. In the invariant subspace method. we employ an algebraic approach to solve the time fractional Ivancevic option pricing model.
