How to pass on a list variable containing trading holidays to MyCalendar(bt.TradingCalendar) to overcome resampling problem?

[mahaaveer]

I am resampling daily data to weekly using cerebro.resampledata()
Since some of the fridays are holidays, it needs to be added to the calendar for resampling to work as intended.

In main function, i calculate those missing fridays and have a list ready:

stockdf_daily = pd.read_csv(stock_datapath,
                        dayfirst=True,
                        parse_dates=True,
                        index_col=0)
stock_data_daily = PandasData(dataname=stockdf_daily)
stockdf_daily.index = pd.to_datetime(stockdf_daily.index)
miss_dates = pd.date_range(
    start=stockdf_daily.index.min(), end=stockdf_daily.index.max()).difference(stockdf_daily.index)
miss_dates = miss_dates.tolist()
missed_fridays = []
for date in miss_dates:
    day = date.weekday()
    if day == 4:
        date = date.date()
        missed_fridays.append(date)
cerebro.adddata(stock_data_daily)
cerebro.resampledata(stock_data_daily,
                     timeframe=bt.TimeFrame.Weeks,
                     compression=1)
cerebro.addcalendar(MyCalendar)

Manually adding some 50+ days seems counter productive. How do i pass on this list variable to params of MyCalendar ?

class MyCalendar(bt.TradingCalendar):
    global missed_fridays
    params = {
        'open': time(9, 15),
        'close': time(15, 30),
        'holidays': missed_fridays,
    }
