Usage

The pwb-toolbox package offers a range of functionalities for systematic trading analysis. Here are some examples of how to utilize the package:

• Import pwb_toolbox.datasets and sequentially loads datasets for different asset classes, such as bonds, commodities, cryptocurrencies, ETFs, forex, indices, and stocks, using the load_dataset function:

import pwb_toolbox.datasets as pwb_ds

df = pwb_ds.get_pricing(["AAPL", "MSFT", "GOOGL"])
df = pwb_ds.load_dataset("Bonds-Daily-Price")
df = pwb_ds.load_dataset("Commodities-Daily-Price")
df = pwb_ds.load_dataset("Cryptocurrencies-Daily-Price")
df = pwb_ds.load_dataset("ETFs-Daily-Price")
df = pwb_ds.load_dataset("Forex-Daily-Price")
df = pwb_ds.load_dataset("Indices-Daily-Price")
df = pwb_ds.load_dataset("Stocks-Daily-Price")

• Load daily stock price data for specific symbols using the load_dataset function. The first call retrieves data for Apple and Microsoft. The second call retrieves the same stocks but without price adjustments (adjust=False). The third call loads daily price data for the S&P 500 index:

import pwb_toolbox.datasets as pwb_ds

df = pwb_ds.load_dataset(
    "Stocks-Daily-Price",
    ["AAPL", "MSFT"],
)

df = pwb_ds.load_dataset(
    "Stocks-Daily-Price",
    ["AAPL", "MSFT"],
    adjust=False,
)

df = pwb_ds.load_dataset(
    "Stocks-Daily-Price",
    ["sp500"],
)

• The extend=True argument instructs the function to return an extended historical data using indices, commodities, and bonds data.

import pwb_toolbox.datasets as pwb_ds

df = pwb_ds.load_dataset(
    "ETFs-Daily-Price",
    ["SPY", "IEF"],
    extend=True,
)

• The argument rate_to_price=False specifies that bond yield rates should not be converted to price values in the returned data:

import pwb_toolbox.datasets as pwb_ds

df = pwb_ds.load_dataset(
    "Bonds-Daily-Price",
    ["US10Y"],
    rate_to_price=False,
)

• The argument to_usd=False indicates that the data should not be converted to U.S. dollars, implying that it might be available in another currency.

import pwb_toolbox.datasets as pwb_ds

df = pwb_ds.load_dataset(
    "Indices-Daily-Price",
    ["US10Y"],
    to_usd=False,
)

Backtest engine

The pwb_toolbox.backtest module offers simple building blocks for running Backtrader simulations. Alpha models generate Insight objects which are turned into portfolio weights and executed via Backtrader orders.

from pwb_toolbox.backtest.examples import GoldenCrossAlpha, EqualWeightPortfolio
from pwb_toolbox.backtest import run_backtest
from pwb_toolbox.backtest.execution_models import ImmediateExecutionModel
from pwb_toolbox.backtest.risk_models import MaximumTotalPortfolioExposure
from pwb_toolbox.backtest.universe_models import ManualUniverseSelectionModel

run_backtest(
    ManualUniverseSelectionModel(["SPY", "QQQ"]),
    GoldenCrossAlpha(),
    EqualWeightPortfolio(),
    execution=ImmediateExecutionModel(),
    risk=MaximumTotalPortfolioExposure(max_exposure=1.0),
    start="2015-01-01",
)

Performance Analysis

After running a backtest you can analyze the returned equity series using the pwb_toolbox.performance module.

from pwb_toolbox.backtest.examples import GoldenCrossAlpha, EqualWeightPortfolio
from pwb_toolbox.backtest import run_backtest
from pwb_toolbox.backtest.execution_models import ImmediateExecutionModel
from pwb_toolbox.performance import total_return, cagr
from pwb_toolbox.performance.plots import plot_equity_curve

result, equity = run_backtest(
    ManualUniverseSelectionModel(["SPY", "QQQ"]),
    GoldenCrossAlpha(),
    EqualWeightPortfolio(),
    execution=ImmediateExecutionModel(),
    start="2015-01-01",
)

print("Total return:", total_return(equity))
print("CAGR:", cagr(equity))

plot_equity_curve(equity)

Plotting utilities require matplotlib; some metrics also need pandas.

Live trading with Interactive Brokers

run_ib_strategy streams Interactive Brokers data and orders. Install ibapi and either atreyu-backtrader-api or ib_insync.

from pwb_toolbox.backtest import IBConnector, run_ib_strategy
from pwb_toolbox.backtest.example.engine import SimpleIBStrategy

data_cfg = [{"dataname": "AAPL", "name": "AAPL"}]
run_ib_strategy(
    SimpleIBStrategy,
    data_cfg,
    host="127.0.0.1",
    port=7497,
    client_id=1,
)

Configure host, port, and client_id to match your TWS or Gateway settings. Test with an Interactive Brokers paper account before trading live.
