How to pass a list of dicts to optstrategy?

[soulmachine]

I want to optimize my strategy with customized parameters, for example:

cerebro.optstrategy(bt.strategies.MA_CrossOver, fast=range(2,8), slow=range(4, 16))

The above configuration generates a lot of parameters that I don't want.

Instead, I want to specify parameters manually as the following:

cerebro.optstrategy(bt.strategies.MA_CrossOver, myparams=[
  {'fast': 2, 'slow': 4},
  {'fast': 4, 'slow': 8},
{'fast': 3, 'slow': 7},
])

How can I achieve this? Thanks

Pass parameters to cerebro as you shown above. In the strategy:

...
params = ((`myprams`, {'fast': 1, 'slow': 5}),)
...
p1 = self.p.myparams['fast']
p2 = self.p.myparams['slow']
...
self.ind1 = bt.Indicators.SMA(period=p1)
self.ind2 = bt.Indicators.SMA(period=p2)
...

I didn't test it, but I don't see any reasons that this should not work.

@ab_trader Good idea, I'll try it, thanks!
