class Volume_Reversal_line(bt.Indicator):
    lines = ('Pr_chg','Std_100day','Avg5d_vol','Past_5d_avg_vol')

    params = (
        ('period',12),
        ('stdperiod',50)
    )

I am referring to the parameters here. The parameters here cannot be adjusted with optstrategy.

optstrategy can adjust the parameters in the strategy, how can I adjust the parameters in the previous section, Custom Indicators?
