1. test in local using above code

   price_dict = gqalgo.algo_get_data(symbols=Universe,
                                 freq=FREQ_DAY,
                                 interval_timedelta=interval,
                                 fill_nan_method="ffill")

return

[AMD] shape:(174, 7)
[INTL] shape:(174, 7)

2. unittest
