Hi,

I have a problem with generating basic TradingAlgorithm object.

When I type the code below,

algo = TradingAlgorithm(initialize = initialize, handle_data = handle_data)

I have an error like this.

TypeError: __init__() missing 1 required positional argument: 'sim_params'

I can't figure out this error and can't find any explanation about sim_params parameter.

Looking forward to getting your response. Thanks.

Hi Mujun,

You can check https://github.com/quantopian/zipline/blob/014f1fc339dc8b7671d29be2d85ce57d3daec343/zipline/utils/run_algo.py#L193

sim_params=SimulationParameters(

                start_session=start,

                end_session=end,

                trading_calendar=trading_calendar,

                capital_base=capital_base,

                data_frequency=data_frequency,

)

sim_params is of SimulationParameters (zipline/finance/trading.py).

Thanks

Ayoub
