About

Online portfolio selection (OLPS) is an important issue in operations research community that studies how to dynamically adjust portfolios according to market changes. In the past, OLPS research relied on a general database called OLPS containing price relatives data of financial assets across different markets. However, with the widespread adoption of data-driven technologies like machine learning in finance, OLPS can no longer meet the needs of OLPS research due to the lack of support for high-dimensional feature spaces. To solve this problem, we propose FinOL, an open financial platform for advancing research in data-driven OLPS. FinOL expands and enriches the previous OLPS database, containing 9 benchmark financial datasets from 1962 to present across global markets. To promote fair comparisons, we evaluate a large number of past classic OLPS methods on FinOL, providing reusable benchmark results for future FinOL users and effectively supporting OLPS research. More importantly, to lower the barriers to research, FinOL provides a complete data-training-testing suite with just three lines of command. We are also committed to regularly updating FinOL with new data and benchmark results reflecting the latest developments and trends in the field. This ensures FinOL remains a valuable resource as data-driven OLPS methods continue evolving.

Overall Framework of FinOL

Why should I use FinOL?

1. FinOL contributes comprehensive datasets spanning diverse market conditions and asset classes to enable large-scale empirical validation;
2. FinOL contributes the most extensive benchmark results to date for portfolio selection methods, providing the academic community an unbiased performance assessment;
3. FinOL contributes a user-friendly Python library for data-driven OLPS research, providing a comprehensive toolkit for academics to develop, test, and validate new OLPS methods.

Installation

Installing via PIP

FinOL is available on PyPI, therefore you can install the latest released version with:

> pip install finol -t your_own_dir

Installing from source

Examples and Tutorials

You can find useful tutorials on how to use FinOL in the tutorials folder.

Here we show a simple application (taken from tutorial_2): we transform asset "AA" into a richer representation.

Using FinOL

To lower the barriers for the research community, FinOL provides a complete data-training-testing suite with just three lines of command.

from finol.data_layer.data_loader import *
from finol.optimization_layer.model_trainer import *
from finol.evaluation_layer.model_evaluator import *


load_dataset_output = load_dataset()
train_model_output = train_model(load_dataset_output)
evaluate_model_output = evaluate_model(load_dataset_output, train_model_output)
