"Hello World"/Quick Start

For a quick demo, do the following:

1. Install alpyen
2. Create a py file that perform either backtesting (use the test_backtesting_macrossing_reshuffle test as an example) or live trading (use the test_live_trading test as an example)
3. For live trading, create a yml control file (use the test_control.yml file as an example)

Example

from alpyen import datacontainer
from alpyen import backtesting
from alpyen import utils

# Read data (assuming that BBH.csv from Yahoo Finance is in the Data folder)
data_folder = 'Data\\'
ticker_name = 'BBH'
file_path = os.path.join(os.path.dirname(__file__), data_folder)
short_lookback = 5
long_lookback = 200
short_lookback_name = ticker_name + '_MA_' + str(short_lookback)
long_lookback_name = ticker_name + '_MA_' + str(long_lookback)
ticker_names = [ticker_name]
all_input = datacontainer.DataUtils.aggregate_yahoo_data(ticker_names, file_path)

# Subscribe to signals
signal_info_dict = {}
signal_info_dict[short_lookback_name]\
    = utils.SignalInfo('MA', ticker_names, [], [], short_lookback, {})
signal_info_dict[long_lookback_name]\
    = utils.SignalInfo('MA', ticker_names, [], [], long_lookback, {})

# Subscribe to strategies
strategy_info_dict = {}
strategy_name = ticker_name + '_MACrossing_01'
strategy_info_dict[strategy_name] = utils.StrategyInfo(
    'MACrossing',
    [short_lookback_name, long_lookback_name],
    1, {}, ticker_names, combo_definition={'combo1': [1.0]})

# Create backtester and run backtest
number_path = 1000
my_backtester = backtesting.Backtester(all_input, ticker_names, signal_info_dict, strategy_info_dict,
                                       number_path)
my_backtester.run_backtest()
backtest_results = my_backtester.get_results()

The

• moving average signal / MA-crossing trading strategy; and
• weighted momentum signal / VAA strategy

are built-in in the package, and are intended to serve as examples. Users can use them as references and create their custom signals/strategies by deriving from the SignalBase class within the signal module, and the StrategyBase class within the strategy module. Note that the package needs a unique signature string for each derived signals/strategies for reflective object creation, so for example:

class MASignal(SignalBase):
    """
    Moving average signal.
    """

    _signal_signature = 'MA'

class MACrossingStrategy(StrategyBase):
    """
    MA Crossing Strategy
    """

    _strategy_signature = 'MACrossing'
