How to implement advanced trading strategies using time series analysis, machine learning and Bayesian statistics with R and Python. Open Sourcing the Forex Trading System For the reasons outlined above I have decided to open-source the forex trading system. The QuantStart Automated Forex Trading System is now open-source under a liberal MIT license. txt Finally you will need to create a symbolic link in your Python virtual environment to allow you to type import qsforex in your code and run it!

Longer-Term Plan The "philosophy" of the forex trading system, as with the rest of the QuantStart site, is to try and mimic real-life trading as much as possible in our backtesting.

So what is currently included in the Forex Trading System to date? Event-Driven Architecture - The forex trading system has been designed as an event-driven system from the ground up, as this is how an intraday trading system will be implemented in a live environment.

Price Streaming - We have a basic price streaming object. This currently handles subscription to only a single pair, but we can easily modify this to subscribe to multiple currency pairs. Signal Generation - We can incorporate trading strategies based directly off past and current tick prices using the Strategy object, which creates SignalEvent objects.

Order Execution - We have a naive order execution system that blindly sends orders from the Portfolio to OANDA. By "blindly" I mean that there is no risk management or position sizing being carried out, nor any algorithmic execution that might lead to reduced transaction costs. GBP Base Currency - To keep things simple, I've only written the system for GBP base currency.

This is perhaps the most important aspect to modify given how many of you will have practice accounts denominated in USD, EUR, CAD, JPY, AUD and NZD! Handling multiple currency pairs is an important next step. This will involve modification to the position and portfolio calculations. Decimal Handling - Any production trading system must correctly handle currency calculations. In particular, currency values should not be stored as floating point data-types, since the rounding errors will accumulate.

Please see this fantastic article on floating point representations for more details. Crucially, this is also unit tested. Local Portfolio Handling - In my opinion carrying out a backtest that inflates strategy performance due to unrealistic assumptions is annoying at best and extremely unprofitable at worst!

Introducing a local portfolio object that replicates the OANDA calculations means that we can check our internal calculations while carrying out practice trading , which gives us greater confidence when we later use this same portfolio object for backtesting on historical data. Since these are so crucial to the calculations of the strategy, one must be extremely confident that they perform as expected. An additional benefit of such tests is that they allow the underlying calculation to be modified, such that if all tests still pass, we can be confident that the overall system will continue to behave as expected.

At this stage the Forex Trading System is lacking the following functionality: Slippage Handling - The system is currently generating a lot of slippage due to the high-frequency nature of the tick data provided from OANDA. This means that the portfolio balance calculated locally is not reflecting the balance calculated by OANDA. Until correct event-handling and slippage adjustment is carried out, this will mean that a backtest will not correctly reflect reality.

Multiple Base Currencies - We are currently restricted to GBP. At the very least we need to include the major currency denominations - USD, EUR, CAD, AUD, JPY and NZD. There are two aspects to this. The first is to correctly handle the calculations when neither the base or quote of a currency pair is equal to the account denomination currency. The second aspect is to support multiple positions so that we can trade a portfolio of currency pairs.

Risk Management - Many "research" backtests completely ignore risk management. Unfortunately this is generally necessary for brevity in describing the rules of a strategy. In reality we -must- use a risk overlay when trading, otherwise it is extremely likely that we will suffer a substantial loss at some stage. This is not to say that risk management can prevent this entirely, but it certainly makes it less likely!

Portfolio Optimisation - In an institutional setting we will have an investment mandate, which will dictate a robust portfolio management system with various allocation rules. Robust Strategies - I have only demonstrated some simple random signal generating "toy" strategies to date.

While the tick data files produced are not huge roughly 3.

Unfortunately, I ran into some trouble and I was not able to download the necessary files in order to test the system. Since I was not too fussed about the actual time series themselves, I felt it would be simpler to write a script to generate simulated forex data myself. py file. The current code can be found here. Since I won't actually ever be testing any real strategies on this data I wasn't too bothered about its statistical properties or its absolute values in relation to real forex currency pairs.

As long as it had the correct format, and approximate length, I could use it to test the multi-day backtesting system. The script is currently hardcoded to generate forex data for the entire month of January csv , where BBBQQQ will be the specified currency pair e. GBPUSD and YYYYMMDD is the specified date e. py in the application root. In order to generate the data the following command must be run, where BBBQQQ must be replaced with the particular currency name of interest, e.

GBPUSD :. The file will require modification in order to generate multiple months or years of data. Each daily tick file is on the order of 3. In the future I will be modifying this script to generate multiple months or years of data based on a list of currency pairs provided, rather than the values being hardcoded.

However, for the time being this should help you get started. Please note that the format exactly matches that of the DukasCopy historical tick data, which is the dataset that I am currently using. Following on directly from the generation of simulated tick data is the implementation of multi-day backtesting.

While my long-term plan is to use a more robust historical storage system such as PyTables with HDF5 , for the time being I am going to make use of a set of CSV files, one file per day per currency pair. This is a scalable solution as the number of days increases. The current implementation exits the backtest upon the receipt of the StopIteration exception thrown by the next.. call to self. In this snippet, when StopIteration is raised, the code checks for the result of self.

If the result is True the backtest continues on self. If the result is False , the backtest ends. This approach is very memory efficient as only a particular days worth of data is loaded at any one point.

It means that we can potentially carry out months of backtesting and are only limited by the CPU processing speed and the amount of data we can generate or acquire. I have updated the documentation to reflect the fact that the system now expects multiple days of data in a particular format, in a particular directory which must be specified.

A backtest is relatively useless if we can't visualise the performance of the strategy over time. While the system has been mostly console-based to date, I have begun the transition to a Graphical User Interface GUI with this release.

In particular, I have created the usual "three pane" of charts that often accompany performance metrics for quantitative trading systems, namely the equity curve, the returns profile and the drawdown curve.
