Parameters

Parameters are an important part of any lumibot program and allow you to customize your strategy to your liking. Parameters are defined in the strategy file and can be accessed by the strategy methods. Parameters can be accessed by the strategy methods by using the get_parameters() method. The get_parameters() method returns a dictionary of all the parameters defined in the strategy file. The parameters can be accessed by using the parameter name as the key. For example, here’s a typical strategy file that defines several parameters:

class MyStrategy(Strategy):
    ############################
    # Defining the initial parameters
    ############################

    # You can define the initial parameters for your strategy by using the following code
    parameters = {
        "my_parameter": 10,
        "main_ticker": "SPY",
        "ema_threshold": 10.5
    }

    def on_trading_iteration(self):
        ############################
        # Getting the parameters
        ############################

        # You can get a parameter by using the following code
        my_parameter = self.get_parameters()["my_parameter"]
        # Or you can get a parameter by using the following code
        main_ticker = self.parameters["main_ticker"]

        ############################
        # Setting the parameters
        ############################

        # You can set a parameter by using the following code
        self.parameters["my_parameter"] = 20
        # Or you can set a parameter by using the following code
        self.set_parameters({"my_parameter": 20})

get_parameters()	Get the parameters of the strategy.
set_parameters(parameters)	Set the default parameters of the strategy.
