For the ith candle OiHiLiCi will correspond to open, high, low and close prices, respectively. In its nature an indicator tries to clear the graphic and to smooth daily unimportant short-lived features and corrections of the trend. With a given radius r, a point on the graphic is a chxrt point if it is extremal in the given radius and does not chartt two equal neighbors: According to the values of these functions for the current moment the trader on the stock market or the system for automatic trading buy an asset or sell one. The strat- egy bets on the fact that most of the times when the price crosses the Moving Average the trend continues in the direction of the candle that has crossed the Average.
In the moment of crossing a signal is generated to close the old position and to open a new one. One of them is defined for a shorter period of time — it will be refered to as fast, and the other as slow. When the fast average crosses the slow one a signal is generated to close the existing position and to open a new one according to the trend direction of the fast Moving Average.
These two parameters set the loss profit in pips which if reached the order closes. The motivation behind these to thresholds is to limit the losses for stop lossand to prevent losing the fc profit for stop profit. The authors suggest using a thresh- old for small and a big candle in order to handle with these two cases. Is it has been mentioned, the strategy generates trading singals when the indicator crosses the trend curve. Weather the new order direction is going to be short or long buying or selling depends on the direction of the crossed candle. Sometimes there is a little statical mistake in the size of the candle.

Therefore when the cande is too small the change in the price is below the threshold for small candedue to the statistical chromowome the direction of the candle can be misleading and a wrong order can be opened. In such case, when the candle is too c, no order is opened. Using this threshold is the authors approach to soving the second cause of unprofitable orders. Usually after a big and fast movement on the market, a smaller movement in opposite direction a correction is generated. Now if the indicator crosses the big candle it is highly possible to cross the correction as well which will generate two consequtive buy and sell signals and the realized oreder will be unprofitable because of the spread the difference between the bid and the ask rates.
Results are shown on figure 1which shows that a strat- egy with these two parameters is performing better and more stable than a strategy without them. Finding of the most optimal con- figuration the most beneficial is equivalent to finding a special point in five-dimensional space.
The authors suggest solving the optimisation problem using genetic algo- rithms. Let an rte is rahe single configuration of the five parameters. Each of the five parameters is refered to as a gene, and its value an allele of the corresponding gene. Using the genetic algorithm a process of evolution will be simulated. Ini- tially a population of chqrt, each with random but valid alleles. Chqrt size of the population was determined after a chromospme of tests and ob- servations, which are shown on figures 4 and 5. The result obtained from population of rwte, 25, 50, and individuals have ratte an- alyzed. They show the little populations up to 25 individuals can harder reach the optimal strategy.
This can be easily explained by the fact that in the smaller populations a fewer number of individuals is used, thus a fewer number of alleles are there, which can later recombine. On the other hand, populations with more than individuals is also not efficient, because in such case there is too much diversity and reaching an optimal solutions is more time-consuming. Next, the way of creating the next generation should be defined. A two individuals from the population are chosen for parents. There are no genders, but for clearness one of the parents will be named mother and the other one father. After the parents are chosen a replication must hold.
Replication will generate two child individuals from the parents using crossingover. The second child individuals is constructed with the alleles from the opposite parent. For the sake of a genetic diversity and avoiding repetitions of individuals mutations are needed. A mutation is a random change in an allele. Two types of mutations have been tested - first, when the allele to be mutated is slightly altered using a Gaussian deviation and second, when a random new value is chosen. In both cases same results were reached, but in the case with the slight change the evolution took much more time. Therefore a mutation with a random new value was chosen.
The purpose is accelerating the evolution, when the individuals become homogeneous.

It is important Tracing note the significance of the mutations: This way the evolution whould have found the best individual with Trxding among the initial set, but not in general. After the child rrate are generated they are moved in the popula- tions, where they subtitude the place of the worst two individuals. Vhromosome way a mechanism of natural selection is implemented - negative mutations generate individuals who perform worse and can be replaced by the new generations if they are better. But how is it determined determined how well an individ perfoms? The so called fitness function is used.
It maps an individ to a scalar value rep- resenting the level of fitness. And because the algorithms aims maximazing the income, a strategy is as well performing as its income. Therefore the function given simulates the activity of the strategy the individ for the last year and returns the incomes. Finally, it should be determined when the evolution whould end. Simul- taneously the results on the working currency pair are observed and also the results on other currency pair a control. At first the result on both the working pair and the conrol are getting better. When the result on the control start to get worse that is an indication the model is starting to overfit.
All in all the algorithm fd the following features: A chromosome of consequent Tradlng values. The strategy itself. Each parameter gets a random valid value. Two random individuals from the population. Two parent individuals generate two child individuals. By cross-validation on a simular currency chrat. We offer the following solution: After a fixed period of time T period of strategy change the system tries to find the best strategy for the last again fixed period P period of backtesting. The sense of the FOREX trading is to buy or sell a currency in order to make profit but that means that there must be someone somewhere in the world who will make the opposite order. But since all traders use this algorithm there will be no such traders and so the market will be deformed eventually and there will be no purpose of its existance.

Examining in detail shows that the system will make great profits until more than 50 percent of working capital on the FOREX market is traded acording to the system. After that point the banks which are the main brokers will gradually begin to lose money, because there will not be enough traders to make the opposite order and so they will try to cut their loses by buying or selling less currency which will force the market to shrink eventually making it meaningless. The simulation was realised on the Java programming language. A brokerage of 1. From May 5 the pre- sented algorithm is trading in real time on the platform Trader. These results will be analyzed in a few months because a larger period of time is needed for a clear validation of the algorithm.
The simulation started with a capital of 10 BGN. In the end of the period the profits were over BGN or 14 pips. Observations show the high efficiency of the algorithm. Floating exchange rates. Most major and relatively stable currencies employ a floating exchange rate or fluctuating exchange ratewhich are determined by the forces of supply and demand. The value of the currency is determined by market factors including interest rates, consumer and inflation data, political climate and fluctuations in the value of critical exports.
Managed float exchange rates. Countries employing a managed float include Indonesia and Singapore. Fixed exchange rates. A fixed exchange rate regime ties the value of the currency to the fluctuations of another currency. The Hong Kong dollar and U. The simple answer?
