However, the methodology can be applied on other asset classes. The application of deep learning in volatility forecasting has been an active area in finance, where deep neural network DNN and recurrent neural network RNN are two popular methods. On the one hand, DNN is a common network architecture, which takes multivariate features as inputs and feeds them into multiple fully connected layers.

On the other hand, due to the strength of capturing the temporal information of data, RNNs or its variants e. Long short-term memory LSTM , Gated recurrent unit GRU , etc have achieved remarkable results for sequential data modelling, such as speech recognition, language forecasting, etc. FX ranges exhibit strong patterns, which usually have economic reasons and are well-understood by traders.

These patterns and the domain knowledge of the causes of the patterns lay the foundation of our modelling process. Our main goal is to capture these economic linked intuitions in our prediction model. Figure 1: The daily log-range average for each minute. Color It exhibits interesting time-related patterns including: The ranges tend to be bigger in London trading hours between 7am and 6pm London time corresponding to more frequent trading activities.

Two humps around 7am and 11am London time corresponding London and New York market open. Various spikes in the ranges correspond to different economic data releases e. Non-farm payroll at pm and fixing trades e. WMR fixing at 4pm. Apart from the observations above, it is also well-known that FX market is heavily influenced by macro economic news and events.

When market absorbs certain unexpected news, the stimulated moves often persists for a while. Because of the intrinsic correlations between different currency pairs, the level of activeness of the whole market are also inter-linked across all major currency pairs. As a result, we often observe the volatility clustering and cross-currency correlations.

The patterns discussed above can be summarised into 3 main categories: time-based seasonality, e. These patterns are backed by economic reasons and hence provide predictability. However, it is clearly a non-trivial problem to capture all these patterns in a single model. In other words, the goal is to build a model to generate range functions in real time. Here is a brief description.

What is a neural network? In short, a neural network is a computational model that mimics the human brain by processing a large number of inputs in order to predict a probable outcome. Technically, networks used for commerce are data analysis protocols that contain a large number of related processing modules together through weighted probabilities.

How neural networks are used in forex Unlike the traditional trading system development scenarios, neural networks use multiple data streams to produce a single output result. Any data that can be quantified can be added to the input used to make a prediction. These networks are used in a wide range of forex market prediction software.

They can be trained to recognize patterns, interpret data, and draw pertinent conclusions about future results. The only drawback in the use of neural networks is the time and effort necessary to train and test them. Still, the profit potential can justify those efforts. The idea is that when the system is presented with samples of input data and the resulting results, the network will learn the dependencies between the input and output data sets.

Looking to the future, the network compares the results themselves to see how close they meet the expected values. As with many test scenarios, a neural network system must be operated using two separate sets of data — in this case a set of tests and a training set. Then, adjust the weighting between the different dependencies until the correct result is calculated exactly.

For example, all system elements communicate with each other to determine a final answer. The neural network is multi-layered and detail-oriented. There are two main databases involved with neural networks. There is a training base as well as a test base. Database improvements are completed through trial and error. The network maintains permanent progress.

The system is always using new information to improve the result. The Forex market has been increasingly expanding its technology to improve trading outcomes. Tech developers have the ability to improve the effectiveness of all forms of artificial intelligence greatly.

The most important feature of neural networks is their ability to gather data and analyze it. This information is then stored and used when it comes time to make predictions. The system takes time to recognize and learn patterns before it can be used consistently with guaranteed success. The process of system learning does not take long, which is another benefit of this quick network.

The different features of the network include immersion, extraction, neural training, and decision-making. These are the steps involved in creating an accurate prediction. The main reason for this is due to their accuracy and intuitive instincts.

They have the ability to analyze fundamental data as well as technical data. Mechanical systems are not well-equipped to analyze this type of data. Human errors are even more common when faced with analyzing this data. This is why neural networks have the ability to benefit traders greatly. Another major benefit of neural networks is their quick adaptability. Neural networks do not take a long time to train.

This is beneficial as it saves time and resources. Neural networks can help bridge the gap between human intelligence and computers. Neural networks are already in use today. Popular search engines such as Google already use neural networks to improve their system. Google uses neural networks to analyze and classify images, text, and other data.

The neural network has the ability to sort images and distinguish certain features from others. Google translate also utilizes neural networks in part. For example, the translations have become more accurate with the use of neural networks. The benefits of these systems include self-learning, highly improved reaction speed, and problem-solving capabilities.

Neural networks have the ability to make a forecast. They can also generalize and highlight the data as well. The network is trained and can make educated predictions based upon the historical information it has saved. Classical indicators are different from neural networks. Neural networks have the ability to view dependencies between data and therefore make adjustments based upon this information. It will take a level of available time and resources to train the network; however, these are minor and worth the outcome.

As with any other system, neural networks have a margin for error. They can produce an inaccurate forecast. Final solutions mainly rely upon input data. Neural networks can decipher patterns and relationships where a human eye can not. The basic idea is that when presented with examples of pairs of input and output data, the network can 'learn' the dependencies, and apply those dependencies when presented with new data.

From there, the network can compare its own output to see how close to correct the prediction was, and go back and adjust the weight of the various dependencies until it reaches the correct answer. This requires that the network be trained with two separate data sets — the training and the testing set.

One of the strengths of neural networks is that it can continue to learn by comparing its own predictions with the data that is continually fed to it. Neural networks are also very good at combining both technical and fundamental data, thus making a best of both worlds scenario. Their very power allows them to find patterns that may not have been considered, and apply those patterns to prediction to come up with uncannily accurate results.

Unfortunately, this strength can also be a weakness in the use of neural networks for trading predictions. Ultimately, the output is only as good as the input. They are very good at correlating data even when you feed them enormous amounts of it. They are very good at extracting patterns from widely disparate types of information — even when no pattern or relationship exists.

Its other major strength — the ability to apply intelligence without emotion — after all, a computer doesn't have an ego — can also become a weakness when dealing with a volatile market.
