#Make a dashboard function to both find the payoffs and also create the graphs
def call_dashboard(strike1, strike2, strike3, periods, rf):
    payoffs = call_payoffs(strike1, strike2, strike3, periods, rf)
    graph_call_options(payoffs, strike1, strike2, strike3)

strike1 = widgets.IntSlider(value=90,
                          min=1,
    max=1000,
                              step = 10,
                              description='Strike 1:'
)

strike2 = widgets.IntSlider(value=95,
                          min=1,
    max=1000,
                              step = 10,
                              description='Strike 2:'
)

strike3 = widgets.IntSlider(value=100,
                          min=1,
    max=1000,
                              step = 10,
                              description='Strike 3:'
)


interact(call_dashboard, strike1=strike1,
         strike2=strike2, strike3=strike3,
         periods=fixed(periods.value), rf=fixed(rf.value));

Now everything is done! We can recreate the two dashboards in two separate cells to play with.

#For ease of use, pull grab the dashboard for simulating returns
interact_manual(simulate_returns, price0=price0, periods=periods, rf=rf, sigma=sigma, runs=runs,
               time_step = widgets.fixed(1/252));

#And then down here put the call option dashboard
strike1 = widgets.IntSlider(value=90,
                          min=1,
    max=1000,
                              step = 10,
                              description='Strike 1:'
)

strike2 = widgets.IntSlider(value=95,
                          min=1,
    max=1000,
                              step = 10,
                              description='Strike 2:'
)

strike3 = widgets.IntSlider(value=100,
                          min=1,
    max=1000,
                              step = 10,
                              description='Strike 3:'
)

interact(call_dashboard, strike1=strike1,
         strike2=strike2, strike3=strike3,
         periods=fixed(periods.value), rf=fixed(rf.value));
