Get params trought superClass

[Federico Bld]

Developing several strategies i have to combine them. So I wrote superclasses, i.e:

class BaseStrategy(bt.Strategy):
    params = (
        ('loShBo', 2),
        ('isBacktesting', False),       
        ("sizerType", None),  # Must be specified otherwise will be rised an Exception
        ("sizerDictParameters", {"amount": '', "retint": ""}), # Must be specified otherwise will be rised an Exception
    )

class OverBaseStrategy(BaseStrategy):
    params = (
        ('sma',26),
        ('roc',50),
        ('smaRoc',50),
        ('ema',26),
    )

class MyStrategy_01(OverBaseStrategy):
    params = dict(
        stop_loss=0.05,
        trail=0.07, 
    )

When I call:

cerebro = bt.Cerebro()
params = {
    'trail': 0.02,
    'smaRoc': 20,
    'isBacktesting': True}
        cerebro.addstrategy(strategy=MyStrategy_01, **params)
pprint(cerebro.strats[0][0][0].params.__dict__)

The output is:

mappingproxy({'__doc__': None,
              '__module__': 'backtrader.metabase',
              '_getpairs': <classmethod object at 0x0000024E510751F0>,
              '_getpairsbase': <classmethod object at 0x0000024E51075190>,
              '_getrecurse': <classmethod object at 0x0000024E51075250>,
              'stop_loss': 0.05,
              'trail': 0.07})

What can I do to retrive all params with superclasses included?
i.e. :

mappingproxy({
    '__doc__': None,
    '__module__': 'backtrader.metabase',
    '_getpairs': <classmethod object at 0x0000024E510751F0>,
    '_getpairsbase': <classmethod object at 0x0000024E51075190>,
    '_getrecurse': <classmethod object at 0x0000024E51075250>,
    'loShBo': 2,
    'isBacktesting': True,  # <== NOT False as default
    'sizerType': None,
    'sizerDictParameters': {"amount": '', "retint": ""},
    'sma': 26,
    'roc': 20,
    'smaRoc': 20,  # <== NOT 50 as default
    'ema': 26,
    'stop_loss': 0.05,
    'trail': 0.02,  # <== NOT 0.07 as default
})
