Indeed, research has shown that the profitability of simple trading rules persisted in foreign exchange and other markets for a period of decades. The widespread availability of data, analytical tools and computing power has, arguably, contributed to the increased efficiency of financial markets and complicated the search for profitable trading ideas.

And there is no guarantee that the end result will produce genetic trading systems required investment returns. One such approach is Genetic Programming, genetic trading systems. Haftan had proposed creating trading strategies by applying the kind of techniques widely used to analyze voluminous and highly complex data sets in genetic research. I was genetic trading systems skeptical of the idea and spent the next 18 months kicking the tires very hard indeed, of behalf of an interested investor, genetic trading systems.

One of the challenges I devised was to create data sets in which real and synthetic stock series were mixed together and given to the system evaluate. Some of the patterns I created were quite simple, such as introducing a drift component. But other patterns genetic trading systems more nuanced, for example, using a fractal Brownian motion generator to induce long memory in the stock volatility process.

It was when I saw the system detect and exploit the patterns buried deep within the synthetic series to create sensible, profitable strategies that I began to pay attention. A short time thereafter Haftan and I joined forces to create what became the Proteom Fund. The heat thrown off from the cluster was immense, and when combined with very loud rap music blasted through the walls by the neighboring music studios, the effect was debilitating.

As you might imagine, meetings with investors were a highly unpredictable experience. The Genetic Programming Approach to Building Trading Models Genetic programming is an evolutionary-based algorithmic methodology which can be used in a very general way to identify patterns or rules within data structures. The GP system is given a set of instructions typically simple operators like addition and subtractionsome data observations and a fitness function to assess how well the system is able to combine the functions and data to achieve a specified goal.

In the trading strategy context the data observations might include not only price data, but also price volatility, moving averages and a variety of other technical indicators. The fitness function could be something as simple as net profit, but might represent alternative measures of profitability or risk, with factors such as PL per trade, win rate, or maximum drawdown.

The length of the program might also be constrained in terms of the maximum permitted lines of code, genetic trading systems. We can represent what is going on using a tree graph : In this example the GP system is combining several simple operators with the Sin and Cos trig functions to create a signal comprising an expression in two variables, genetic trading systems, X and Y, which may be, for example, genetic trading systems, stock prices, moving averages, or technical indicators of momentum or mean reversion.

System performance is re-evaluated using the fitness function and the most profitable mutations are retained for further generation, genetic trading systems. The resulting models are often highly non-linear and can be very general in form.

A GP Daytrading Strategy The last fifteen years has seen tremendous advances in the field of genetic programming, in terms of the theory as well as practice. A researcher can develop and evaluate tens of millions of possible trading algorithms with the space genetic trading systems a few hours. Implementing genetic trading systems thoroughly researched and tested strategy is now feasible in a matter of weeks.

But does it work? The system trades a single contract in each market individually, going long and short several times a day. Only the most liquid period in each market is traded, which typically coincides with the open-outcry session, with any open positions being exited at the end of the session using market orders.

With the exception of the NG and HO markets, which are entered using stop orders, all of the markets are entered and exited using standard limit orders, at prices determined by genetic trading systems system The system was constructed using minute bar data from Jan to Dec and tested out-of-sample of data from Jan to May The in-sample span of data was chosen to cover periods of extreme market stress, as well as less volatile market conditions.

A lengthy out-of-sample period, almost half the span of the in-sample period, was chosen in order to evaluate the robustness of the system.

The reduction in risk in the out-of-sample period is also reflected in lower Value-at-Risk and Drawdown levels. Overall, the system appears to be not only highly profitable, but also extremely robust. This is impressive, given that the models were not updated with data afterremaining static over a period almost half as long as genetic trading systems span of data used in their construction. It is reasonable to expect that out-of-sample performance might be improved by allowing the models to be updated with more recent data, genetic trading systems.

Benefits and Risks of the GP Approach to Trading System Development The potential benefits of the GP approach to trading system development include speed of development, genetic trading systems, flexibility of design, generality of application across markets and rapid testing and deployment.

What about the downside? The most obvious concern is the risk of over-fitting. By allowing the system to develop and test millions of models, there is a distinct risk that the resulting systems may be too closely conditioned on the in-sample data, and will fail to maintain performance when faced with new market conditions.

That is why, of course, genetic trading systems, we retain a substantial span of out-of-sample data, genetic trading systems, in order to evaluate the robustness of the trading system. Even so, given the enormous number of models evaluated, genetic trading systems, there remains a significant risk of over-fitting.

Not being able to explain precisely how a system makes money is troubling enough in good times; but in bad times, during an extended drawdown, investors are likely to become agitated very quickly indeed if no explanation is forthcoming. Unfortunately, evaluating the question of whether a period of poor performance is temporary, or the result of a breakdown in the model, genetic trading systems, can be a complicated process.

Finally, in comparison with other modeling techniques, GP models suffer from an inability to easily update the model parameters based on new data as it become available. Typically, as GP model will be to rebuilt from scratch, often producing very different results each time.

Conclusion Despite the many limitations of the GP approach, genetic trading systems, the advantages in terms of the speed and cost of researching and developing original trading signals and strategies have become increasingly compelling. Given the several well-documented successes of the GP genetic trading systems in fields as diverse as genetics and physics, genetic trading systems, I think an appropriate position to take with respect to applications within financial market research would be one of cautious optimism.
