Dubai: When Bernd Skorupinski came to Dubai by way of Germany six years ago, he had no idea he would leave his job to become a fulltime trader. Foreign exchange currency trading, commonly referred to as forex, is a market where banks, businesses, investors and traders come to exchange and speculate on rising or dropping currencies. But to Skorupinski, the appeal to trade came from not only investing in an open market that requires little to feed and leverage, but also investing in himself. According to Abu Hantash, forex trading is more popular in the UAE than ever before, citing the number viet jet ipo brokers that have sprang up.

Many individuals believe this is worth the premium they pay. Sometimes, when a good is priced high, an individual will automatically assume it to be of better quality, when in fact it is not necessarily so. Many companies source or produce their goods in the same regions or factories, but because of marketing and brand identity, some are sold at a premium.

Consumers automatically associate the higher price with better quality. If the price is increased on the same good, consumers may then perceive this as improved quality and are willing to pay the higher price. Similarly, when a good is perceived as difficult to purchase, an affluent consumer is willing to pay more for it.

This is commonly seen in the art world. Paintings from deceased artists, such as Picasso or Monet, fetch millions of dollars, due to the fact that a limited quantity exists. The price does not necessarily reflect the quality of the art but the fact that the artist's paintings are not readily available in society. Real Estate Investing.

Veblen goods are typically high-quality goods that are made well, are exclusive, and are a status symbol.

Veblen goods are generally sought after by affluent consumers who place a premium on the utility of the good. Examples of Veblen goods include designer jewelry, yachts, and luxury cars. The demand curve for a Veblen good is upward sloping, contrary to a normal demand curve, which is downward sloping. Most often, when the price of a Veblen good goes up, the demand goes up; when the price of a Veblen good goes down, the demand goes down.

Getting Familiar with Giffen Goods Giffen goods are non-luxury items that generate higher demand when prices rise, creating an upward-sloping demand curve contrary to standard laws of demand.

Thorstein Veblen Thorstein Veblen was an American economist best known for coining the term "conspicuous consumption," which appeared in his book "The Theory of the Leisure Class. When the pirates told him that they had set his ransom at the sum of 20 talents approx kg of silver , he mocked at them for not knowing whom they had captured and suggested that 50 talents kg of silver would be a more appropriate amount.

He then sent his followers out to gather the money and settled in for a period of captivity. The pirates were dumbfounded. A hostage rarely negotiates his ransom. The task took 38 days. Once he was freed, Caesar managed to quickly raise a small fleet which he took back to the island where he had been held captive. He captured and killed them and took back his 50 talents of silver, along with all their possessions. Perhaps the most powerful psychological flaw exists among investors is the bandwagon effect, where people alter their behaviour to fit in with the crowd.

This can lead to groupthink, where the market effectively becomes one person rather than a group of individuals. They are not any better than their counterparts. Their price alone makes them desirable. The most obvious paradox concerns function. Luxury goods are not purchased to satisfy so-called primary needs such as clothing, hunger, thirst, shelter or transport. Their function is psychological-they promote a sense of being financially powerful, and they serve as markers of a real or projected status in society.

The function of luxury goods is largely a derivative of their price. The retail price at which most luxury goods are sold can contradict classic economic theory as demand, instead of increasing with a decrease in price, follows the opposite curve. A bottle of perfume that costs 85 euros can be more attractive to a purchaser than a bottle costing 20 euros, although intrinsic differences might be insignificant.

But the demand curve does not increase indefinitely with the price. Once a certain threshold has been reached, demand will drop or fall away completely. But the propensity to purchase goods and services on account of the higher rather than lower price differential compared to average prices in a generic category is undoubtedly one of the principal characteristics of the luxury domain. As a society, we are so obsessed with how the rich live their conspicuous lives.

I think it has more to do with psychology than sociology. To the conspicuous consumer, a public display of wealth and power is a means either of attaining or of maintaining a given social status. Flashy people in society use such behaviour to maintain or gain higher social status. Flashiness as behaviour is deeply entrenched in the culture of our society. It is imperative to recognise how conspicuous consumption directs our spending habits and our consumption pattern.

This can be seen where people boast about how little they paid for a typically expensive item. It can also be a motivator for buying in sales and low-cost outlets.

While there is no specific price point that can be identified as the dividing line between a Veblen good and a normal product, it may be safe to assume that a Veblen good is generally priced exponentially higher than a basic product in the same category. Take the case of watches. Studies indicate that people are happier and receive more utility with the purchase of a Veblen good. This is a result of the good making the individual feel more exclusive and important, with the knowledge that they are purchasing something of high quality that is out of reach for others.

Metrics details. Forex foreign exchange is a special financial market that entails both high risks and high profit opportunities for traders.

It is also a very simple market since traders can profit by just predicting the direction of the exchange rate between two currencies. However, incorrect predictions in Forex may cause much higher losses than in other typical financial markets. The direction prediction requirement makes the problem quite different from other typical time-series forecasting problems.

We utilized two different data sets—namely, macroeconomic data and technical indicator data—since in the financial world, fundamental and technical analysis are two main techniques, and they use those two data sets, respectively.

Our proposed hybrid model, which combines two separate LSTMs corresponding to these two data sets, was found to be quite successful in experiments using real data. The foreign exchange market, known as Forex or FX, is a financial market where currencies are bought and sold simultaneously. It is a decentralized market that operates 24 h a day, except for weekends, which makes it quite different from other financial markets.

The characteristics of Forex show differences compared to other markets. These differences can bring advantages to Forex traders for more profitable trading opportunities. Two types of techniques are used to predict future values for typical financial time series—fundamental analysis and technical analysis—and both can be used for Forex.

The former uses macroeconomic factors while the latter uses historical data to forecast the future price or the direction of the price. The main decision in Forex involves forecasting the directional movement between two currencies. Traders can profit from transactions with correct directional prediction and lose with incorrect prediction.

Therefore, identifying directional movement is the problem addressed in this study. In recent years, deep learning tools, such as long short-term memory LSTM , have become popular and have been found to be effective for many time-series forecasting problems. In general, such problems focus on determining the future values of time-series data with high accuracy.

However, in direction prediction problems, accuracy cannot be defined as simply the difference between actual and predicted values. Therefore, a novel rule-based decision layer needs to be added after obtaining predictions from LSTMs. We first separately investigated the effects of these data on directional movement. After that, we combined the results to significantly improve prediction accuracy. This can be interpreted as a fundamental analysis of price data. The other model is the technical LSTM model, which takes advantage of technical analysis.

Technical analysis is based on technical indicators that are mathematical functions used to predict future price action. A popular deep learning tool called LSTM, which is frequently used to forecast values in time-series data, is adopted to predict direction in Forex data.

A novel hybrid model is proposed that combines two different models with smart decision rules to increase decision accuracy by eliminating transactions with weaker confidence. The proposed model and baseline models are tested using recent real data to demonstrate that the proposed hybrid model outperforms the others.

The rest of this paper is organized as follows. Moreover, the preprocessing and postprocessing phases are also explained in detail. Various forecasting methods have been considered in the finance domain, including machine learning approaches e. Unfortunately, there are not many survey papers on these methods.

Cavalcante et al. The most recent of these, by Cavalcante et al. Although that study mainly introduced methods proposed for the stock market, it also discussed applications for foreign exchange markets. There has been a great deal of work on predicting future values in stock markets using various machine learning methods. We discuss some of them below. Selvamuthu et al. Patel et al. In the first stage, support vector machine regression SVR was applied to these inputs, and the results were fed into an artificial neural network ANN.

SVR and random forest RF models were used in the second stage. They reported that the fusion model significantly improved upon the standalone models. Guresen et al. Weng et al. Market prices, technical indicators, financial news, Google Trends, and the number unique visitors to Wikipedia pages were used as inputs. They also investigated the effect of PCA on performance. Huang et al.

They compared SVM with linear discriminant analysis, quadratic discriminant analysis, and Elman back-propagation neural networks. They also proposed a model that combined SVM with other classifiers. Their direction calculation was based on the first-order difference natural logarithmic transformation, and the directions were either increasing or decreasing. Kara et al.

Ten technical indicators were used as inputs for the model. They found that ANN, with an accuracy of In the first approach, they used 10 technical indicator values as inputs with different parameter settings for classifiers. Prediction accuracy fell within the range of 0. In the other approach, they represented same 10 technical indicator results as directions up and down , which were used as inputs for the classifiers.

Although their experiments concerned short-term prediction, the direction period was not explicitly explained. Ballings et al. They used different stock market domains in their experiments. According to the median area under curve AUC scores, random forest showed the best performance, followed by SVM, random forest, and kernel factory.

Hu et al. Using Google Trends data in addition to the opening, high, low, and closing price, as well as trading volume, in their experiments, they obtained an Gui et al. That study also compared the result for SVM with BPNN and case-based reasoning models; multiple technical indicators were used as inputs for the models.

That study found that SVM outperformed the other models with an accuracy of GA was used to optimize the initial weights and bias of the model. Two types of input sets were generated using several technical indicators of the daily price of the Nikkei index and fed into the model. They obtained accuracies Zhong and Enke used deep neural networks and ANNs to forecast the daily return direction of the stock market. They performed experiments on both untransformed and PCA-transformed data sets to validate the model.

In addition to classical machine learning methods, researchers have recently started to use deep learning methods to predict future stock market values. LSTM has emerged as a deep learning tool for application to time-series data, such as financial data. Zhang et al. By decomposing the hidden states of memory cells into multiple frequency components, they could learn the trading patterns of those frequencies.

They used state-frequency components to predict future price values through nonlinear regression. They used stock prices from several sectors and performed experiments to make forecasts for 1, 3, and 5 days. They obtained errors of 5. Fulfillment et al. He aimed to predict the next 3 h using hourly historical stock data.

The accuracy results ranged from That study also built a stock trading simulator to test the model on real-world stock trading activity. With that simulator, he managed to make profit in all six stock domains with an average of 6. Nelson et al. They used technical indicators i. They compared their model with a baseline consisting of multilayer perceptron, random forest, and pseudo-random models.

The accuracy of LSTM for different stocks ranged from 53 to They concluded that LSTM performed significantly better than the baseline models, according to the Kruskal—Wallis test. They investigated many different aspects of the stock market and found that LSTM was very successful for predicting future prices for that type of time-series data.

They also compared LSTM with more traditional machine learning tools to show its superior performance. Similarly, Di Persio and Honchar applied LSTM and two other traditional neural network based machine learning tools to future price prediction. They also analyzed ensemble-based solutions by combining results obtained using different tools. In addition to traditional exchanges, many studies have also investigated Forex.

Some studies of Forex based on traditional machine learning tools are discussed below. Galeshchuk and Mukherjee investigated the performance of a convolutional neural network CNN for predicting the direction of change in Forex. That work used basic technical indicators as inputs. Ghazali et al. To predict exchange rates, Majhi et al. They demonstrated that those new networks were more robust and had lower computational costs compared to an MLP trained with back-propagation.

In what is commonly called a mark-to-market approach, market prices are increasingly being used to calibrate models to quantify risk in several sectors. The net present value of a financial institution, for example, is an important input for estimating both bankruptcy risk e. In such a context, stock price crashes not only dramatically damage the capital market but also have medium-term adverse effects on the financial sector as a whole Wen et al.

Credit risk is a major factor in financial shocks. Therefore, a realistic appraisal of solvency needs to be an objective for banks. At the level of the individual borrower, credit scoring is a field in which machine learning methods have been used for a long time e.

In one recent work, Shen et al. They were able to show that deep learning approaches outperformed traditional methods. Even though LSTM is starting to be used in financial markets, using it in Forex for direction forecasting between two currencies, as proposed in the present work, is a novel approach. Forex has characteristics that are quite different from those of other financial markets Archer ; Ozorhan et al.

To explain Forex, we start by describing how a trade is made. If the ratio of the currency pair increases and the trader goes long, or the currency pair ratio decreases and the trader goes short, the trader will profit from that transaction when it is closed. Otherwise, the trader not profit. When the position closes i. When the position closes with a ratio of 1.

Furthermore, these calculations are based on no leverage. If the trader uses a leverage value such as 10, both the loss and the gain are multiplied by Here, we explain only the most important ones. Base currency, which is also called the transaction currency, is the first currency in the currency pair while quote currency is the second one in the pair.

Being long or going long means buying the base currency or selling the quote currency in the currency pair. Being short or going short means selling the base currency or buying the quote currency in the currency pair. In general, pip corresponds to the fourth decimal point i.

Pipette is the fractional pip, which corresponds to the fifth decimal point i. In other words, 1 pip equals 10 pipettes. Leverage corresponds to the use of borrowed money when making transactions. A leverage of indicates that if one opens a position with a volume of 1, the actual transaction volume will be After using leverage, one can either gain or lose times the amount of that volume. Margin refers to money borrowed by a trader that is supplied by a broker to make investments using leverage.

Bid price is the price at which the trader can sell the base currency. Ask price is the price at which the trader can buy the base currency. Spread is the difference between the ask and bid prices. A lower spread means the trader can profit from small price changes. Spread value is dependent on market volatility and liquidity. Stop loss is an order to sell a currency when it reaches a specified price.

This order is used to prevent larger losses for the trader. Take profit is an order by the trader to close the open position transaction for a gain when the price reaches a predefined value. This order guarantees profit for the trader without having to worry about changes in the market price. Market order is an order that is performed instantly at the current price. Swap is a simultaneous buy and sell action for the currency at the same amount at a forward exchange rate. This protects traders from fluctuations in the interest rates of the base and quote currencies.

If the base currency has a higher interest rate and the quote currency has a lower interest rate, then a positive swap will occur; in the reverse case, a negative swap will occur. Fundamental analysis and technical analysis are the two techniques commonly used for predicting future prices in Forex.

While the first is based on economic factors, the latter is related to price actions Archer Fundamental analysis focuses on the economic, social, and political factors that can cause prices to move higher, move lower, or stay the same Archer ; Murphy These factors are also called macroeconomic factors. Technical analysis uses only the price to predict future price movements Kritzer and Service This approach studies the effect of price movement. Technical analysis mainly uses open, high, low, close, and volume data to predict market direction or generate sell and buy signals Archer It is based on the following three assumptions Murphy :.

Chart analysis and price analysis using technical indicators are the two main approaches in technical analysis. While the former is used to detect patterns in price charts, the latter is used to predict future price actions Ozorhan et al. LSTM is a recurrent neural network architecture that was designed to overcome the vanishing gradient problem found in conventional recurrent neural networks RNNs Biehl Errors between layers tend to vanish or blow up, which causes oscillating weights or unacceptably long convergence times.

In this way, the architecture ensures constant error flow between the self-connected units Hochreiter and Schmidhuber The memory cell of the initial LSTM structure consists of an input gate and an output gate. While the input gate decides which information should be kept or updated in the memory cell, the output gate controls which information should be output.

This standard LSTM was extended with the introduction of a new feature called the forget gate Gers et al. The forget gate is responsible for resetting a memory state that contains outdated information. LSTM offers an effective and scalable model for learning problems that includes sequential data Greff et al. It has been used in many different fields, including handwriting recognition Graves et al.

In the forward pass, the calculation moves forward by updating the weights Greff et al. The weights of LSTM can be categorized as follows:. The other main operation is back-propagation. Calculation of the deltas is performed as follows:. Then, the calculation of the gradient of the weights is performed.

The calculations are as follows:. Using Eqs. A technical indicator is a time series that is obtained from mathematical formula s applied to another time series, which is typically a price TIO These formulas generally use the close, open, high, low, and volume data.

Technical indicators can be applied to anything that can be traded in an open market e. They are empirical assistants that are widely used in practice to identify future price trends and measure volatility Ozorhan et al. By analyzing historical data, they can help forecast the future prices. According to their functionalities, technical indicators can be grouped into three categories: lagging, leading, and volatility. Lagging indicators, also referred to as trend indicators, follow the past price action.

Leading indicators, also known as momentum-based indicators, aim to predict future price trend directions and show rates of change in the price. Volatility-based indicators measure volatility levels in the price. BB is the most widely used volatility-based indicator. Moving average MA is a trend-following or lagging indicator that smooths prices by averaging them in a specified period.

In this way, MA can help filter out noise. MA can not only identify the trend direction but also determine potential support and resistance levels TIO It is a trend-following indicator that uses the short and long term exponential moving averages of prices Appel MACD uses the short-term moving average to identify price changes quickly and the long-term moving average to emphasize trends Ozorhan et al.

Rate of change ROC is a momentum oscillator that defines the velocity of the price. This indicator measures the percentage of the direction by calculating the ratio between the current closing price and the closing price of the specified previous time Ozorhan et al.

Momentum measures the amount of change in the price during a specified period Colby It is a leading indicator that either shows rises and falls in the price or remains stable when the current trend continues. Momentum is calculated based on the differences in prices for a set time interval Murphy The relative strength index RSI is a momentum indicator developed by J.

Welles Wilder in RSI is based on the ratio between the average gain and average loss, which is called the relative strength RS Ozorhan et al. RSI is an oscillator, which means its values change between 0 and It determines overbought and oversold levels in the prices. Bollinger bands BB refers to a volatility-based indicator developed by John Bollinger in the s. It has three bands that provide relative definitions of high and low according to the base Bollinger While the middle band is the moving average in a specific period, the upper and lower bands are calculated by the standard deviations in the price, which are placed above and below the middle band.

The distance between the bands depends on the volatility of the price Bollinger ; Ozturk et al. CCI is based on the principle that current prices should be examined based on recent past prices, not those in the distant past, to avoid confusing present patterns Lambert This indicator can be used to highlight a new trend or warn against extreme conditions. Interest and inflation rates are two fundamental indicators of the strength of an economy.

In the case of low interest rates, individuals tend to buy investment tools that strengthen the economy. In the opposite case, the economy becomes fragile. If supply does not meet demand, inflation occurs, and interest rates also increase IRD In such economies, the stock markets have strong relationships with their currencies.

The data set was created with values from the period January —January This 5-year period contains data points in which the markets were open. Table 1 presents explanations for each field in the data set. Monthly inflation rates were collected from the websites of central banks, and they were repeated for all days of the corresponding month to fill the fields in our daily records.

The main structure of the hybrid model, as shown in Fig. These technical indicators are listed below:. Our proposed model does not combine the features of the two baseline LSTMs into a single model. The training phase was carried out with different numbers of iterations 50, , and Our data points were labeled based on a histogram analysis and the entropy approach.

At the end of these operations, we divided the data points into three classes by using a threshold value:. Otherwise, we treated the next data point as unaltered. This new class enabled us to eliminate some data points for generating risky trade orders. This helped us improve our results compared to the binary classification results.

In addition to the decrease and increase classes, we needed to determine the threshold we could use to generate a third class—namely, a no-action class—corresponding to insignificant changes in the data. Algorithm 1 was used to determine the upper bound of this threshold value. The aim was to prevent exploring all of the possible difference values and narrow the search space. We determined the count of each bin and sorted them in descending order. Then, the maximum difference value of the last bin added was used as the upper bound of the threshold value.

As can be seen in Algorithm 1, it has two phases. In the first phase, which simply corresponds to line 2, the whole data set is processed linearly to determine the distributions of the differences, using a simple histogram construction function. The second phase is depicted in detail, corresponding to the rest of the algorithm. The threshold value should be determined based on entropy. Entropy is related to the distribution of the data.

To get balanced distribution, we calculated the entropy of class distribution in an iterative way for each threshold value up until the maximum difference value. However, we precalculated the threshold of the upper bound value and used it instead of the maximum difference value. Algorithm 2 shows the details of our approach. In Algorithm 2, to find the best threshold, potential threshold values are attempted with increments of 0.

Dropping the maximum threshold value is thus very important in order to reduce the search space. Then, the entropy value for this distribution is calculated. At the end of the while loop, the distribution that gives the best entropy is determined, and that distribution is used to determine the increase, decrease, and no-change classes. In our experiments, we observed that in most cases, the threshold upper bound approach significantly reduced the search space i.

For example, in one case, the maximum difference value was 0. In this case, the optimum threshold value was found to be 0. The purpose of this processing is to determine the final class decision. If the predictions of the two models are different, we choose for the final decision the one whose prediction has higher probability.

This is a type of conservative approach to trading; it reduces the number of trades and favors only high-accuracy predictions. Measuring the accuracy of the decisions made by these models also requires a new approach. If that is the case, then the prediction is correct, and we treat this test case as the correct classification. We introduced a new performance metric to measure the success of our proposed method.

We can interpret this metric such that it gives the ratio of the number of profitable transactions over the total number of transactions, defined using Table 2. In the below formula, the following values are used:. After applying the labeling algorithm, we obtained a balanced distribution of the three classes over the data set.

This algorithm calculates different threshold values for each period and forms different sets of class distributions. For predictions of different periods, the thresholds and corresponding number of data points explicitly via training and test sets in each class are calculated, as shown in Table 3. This table shows that the class distributions of the training and test data have slightly different characteristics.

While the class decrease has a higher ratio in the training set and a lower ratio in the test set, the class increase shows opposite behavior.
