Passing params to strategy

[Søren Pallesen]

Is there a way to pass params to the strategy instead of declaring them inside the strategy:

Instead of doing this:

class VolStrategy(bt.SignalStrategy):
    params = (
        ('period1', 3),
        ('af', 0.005),
        ('afmax', 0.02),
        ('period4', 24),
        ('slPerc', 0.9)
    )

I want to do this:

params = (
     ('period1', 3),
     ('af', 0.005),
     ('afmax', 0.02),
     ('period4', 24),
      ('slPerc', 0.9)
)

class VolStrategy(bt.SignalStrategy, params):

The reason is that it will help me split my code into multiple scripts to make the usage more user friendly.

class VolStrategy(bt.SignalStrategy, params)

That syntax would for sure break things.

Why not something like this?

class VolStrategy(bt.SignalStrategy):
    params = params_defined_elsewhere

Indeed yes why not :-) ...sometimes the solution is staring you right in the eyes without you seeing it. Thx !
