Machine learning can help us optimize automatic trading strategies..Machine learning is the modern science of finding patterns and making predictions from data based on work in multivariate statistics, data mining, pattern recognition and advanced/predictive analytics.For example, when detecting fraud in the millisecond it takes to swipe a credit card, machine learning rules not only on information associated with the transaction, such as value and location, but also by leveraging historical and social network data for accurate evaluation of potential fraud.

Machine learning methods are vastly superior in analyzing potential customer churn across data from multiple sources such as transactional, social media, and CRM sources. High performance machine learning can analyze all of a Big Data set rather than a sample of it. This scalability not only allows predictive solutions based on sophisticated algorithms to be more accurate, it also drives the importance of softwares speed to interpret the billions of rows and columns in real-time and to analyze live streaming data.Automatically finding a winning speculative strategy on eurusd

The neural nets attempt to predict a normalized profit factor (gross profit dividedby the gross loss) on a single trade over a certain period in the future. The period in question can range between 3 and 10 days, it is an optimizeable parameter of the strategy. Therefore,our strategy doesnt necessarily use stop losses and take profits, instead, we open a position for a predetermined amount of time and close the position at the end of that period, whatever happened. The net is graded by the percentage of correct predictions weighed by its accuracy.

There are some common pitfalls to be aware of in such strategies where the strategy seems to offer amazing profits but is worthless in real life. The most important precaution is that the period on which the strategy is tested should not be the same as the period on which it is built. Otherwise we can simply generate thousands of complex random strategies and choose the one that works best on one particular period, but its only when we have a positive result on an independent set of data that we can start trusting our strategy. An optimal strategy tested with a recognized simulatorOver 161 trades, the profit factor of our strategyon the test period is 2.87! That means we obtain 2.87 times more profit than drawdown in trades. Although we only get 60.24% profitable trades, they are much more profitable than the losing trades are un-profitable. The final statistics we find very telling is the maximum consecutive drawdown, 5%, and the maximum consecutive profit, 18% of the equity. We have a live account running the strategy but it has been doing so for far too small a time period to assess it this way.

On the chart below you can observe the evolution of volume for EURUSD in the last 16 years. A strategy built using data that is too distant doesnt work anymore. However, our strategy has worked equally well on EUR/USD for the last few years and nothing hints that it will change anytime soon. There are two things we can do to guard against a sudden change in the way forex instruments are traded.First, we can monitor the market and wait for that moment when our strategy doesnt work anymore using the statistics that the strategy should follow like the maximum consecutive drawdown and by monitoring the volume. Secondly, we can do whats called on-line learning where our strategy is continuously being optimized on new data. This second option is good practice but it doesnt guard against the sudden changes that are typical in forex every few years.Machine learning methods are vastly superior in analyzing potential customer churn across data from multiple sources such as transactional, social media, and CRM sources.
