I apologize for the somewhat sloppyness of this program. I'm trying to sell when the if statement says to. The print statements all run, the counter resets, but it never sells. Can anyone help me with this?

Also, some of the comments won't make sense. I'd just changed this from an SPY/GLD algorithm - which worked fine.

    # Rebalance every day, 1 hour after market open.  
    schedule_function(my_rebalance, date_rules.every_day())  
    context.counter = 0  
    context.trades = 0 #will track how many times a buy signal is executed  
    context.days_invested = 0  
    pipe = Pipeline()  
    attach_pipeline(pipe, name='VIX_pipeline')  
    pipe.add(cboe_vix.close.latest, 'vix')

    if context.VIX.iloc[0,0] >= 25 and context.portfolio.positions[context.VIXY].amount == 0:  
        order_percent(context.VIXY, 1.0)  
        context.counter = 0  
        print("counter reset on buy order")  
    if context.VIX.iloc[0,0] < 25 and context.portfolio.positions[context.VIXY].amount > 0 and context.counter >= 15:

        print("VIX: " + str(context.VIX.iloc[0,0]))  
        print("Current position in VIXY: " + str(context.portfolio.positions[context.VIXY].amount))  
    context.counter = context.counter + 1  
def handle_data(context,data):  
    #Called every minute.  
    pass
