Before revision:  Time-fractional Black-Scholes models subdiffusive and superdiffusive behavior of the prices at the stock market  .
After revision:  Time-fractional Black-Scholes models subdiffusive and superdiffusive behavior of the prices at the stock market . This work shows the flexibility of the radial basis function scheme to solve multidimensional problems with several types of nodes and it also shows how to reduce the condition number of the matrices involved .
