How to optimize custom indicator parameters？

[han shen]

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

I could not get optstrategy to work

so I put the cerebro calls inside of a loop that varies the parameters I send to the
addstrategy call.

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.

I would expect that you would have to pass the period,stdperiod values when in instantiate the class.
