About the QuantSoftware ToolKit

QSToolKit (QSTK) is a Python-based open source software framework designed to support portfolio construction and management. We are building the QSToolKit primarily for finance students, computing students, and quantitative analysts with programming experience. You should not expect to use it as a desktop app trading platform. Instead, think of it as a software infrastructure to support a workflow of modeling, testing and trading.

Key components of QSTK are:

  • Data: A data access package that enables fast reading of historical data (qstkutil.DataAccess).
  • Processing tools: Uses pandas, a Python package designed for time series evaluation of equity data.
  • Portfolio optimization: Using the CVXOPT library.
  • Event studies: An efficient event analyzer, Event_Profiler.
  • Simulation: A simple backtester, quicksim, that includes transaction cost modeling.

Assumptions & Supported Platforms

We support Mac OS X and Ubuntu Linux on Intel machines. We recommend a 2.0 GHz processor and 2GB of RAM as a minimum. QSTK does run on Windows machines, but we don't guarantee it, and we can't always help you if you run into problems.

We make some assumptions about the you should know about that may limit QSTK's use, including:

  • Frequency: Daily trading (versus intra-day high frequency trading);
  • Equities: Publicly traded equities for which historical data are available;
  • Calendars: US market calendars (e.g. NYSE open/close).

Having said that, the tool kit can easily be adapted for other trading regimes. You might want to scan our to see some examples of what you can do with QSTK.
