Introduction
In the current article, we will talk in more detail about the importance of passing meaningful data, the so-called time series, in a neural network. In particular, we will pass our favorite indicators. To achieve this, I will introduce some new concepts that I use while working with neural networks. Although, I think this is not the limit, and over time I will have a new vision in understanding what and how exactly needs to be passed.
Background and observations
Reading a large number of articles on this topic, I constantly observe a sad picture of the direct results of trading systems based on neural networks. Many good ideas and algorithms do not bring the desired results.
The same picture is always observed while passing input parameters. For example, direct passing of the oscillator values, which, in my opinion, has nothing in common with the price of an asset. Oscillators have a well-known problem - the so-called divergence. These are the values of Open, Close, High and Low prices that, when passed directly, do not carry any meaning, but bring into the system incomprehensible noise. These values are not tied to anything and have a significant spread over time. As an example, open the daily chart of any currency pair and look at the range of Close price fluctuations.
Theory and concepts
In this section, I will describe some of the concepts that I have classified for myself and use in my experiments.
- Distances – distance of any indicator to another indicator or its zero value. In my opinion, the main principle is to link the current situation to a stable value in history. If we pass the direct value of the MA 1 indicator, we will get an incomprehensible sample spread since the price value changes over time without any certain range, which implies classification or the slightest hint of statistical behavior. It is a different matter when we convey the difference between two indicators (for example, MA 1 and MA 100 in points or the current distance on the zero candle of the MACD indicator with its value 4 candles ago). Thus, by using distances, we can determine whether the market has moved far from its average and whether it is considerably overbought or oversold compared to the history sample at the current moment. Also, using distance, we determine where the market is moving up or down. The value can be either a positive or negative.
- Accumulation – calculation of the total value of the indicator or indicators relative to each other or their zero point or zero value points in some indicators other than zero. Thus, accumulation allows us to determine how long a particular movement in a certain direction takes place. If the accumulation is small, perhaps consolidation is now underway. Conversely, if the accumulation is large, there is a protracted trend. Direction depends on the sign (- or +). In other words, accumulation values do not have large values during consolidation "turbulence", while having them during trends instead.
- Slope angles – current slope angle of the indicator is a very good way to inform the neural network about the current impulse movement or its absence and the attenuation of activity on the instrument. The ability to determine the slope angles of indicators for a certain history, for example, 10 candles, has proven itself well in analyzing the current situation in comparison with the results of sampling on history. I measure slope angles in radians. This is the only method that suits me personally and does not depend on the chart scale.
Examples
Examples of using distances:
- Passing distances on the current zero candle. MA 1 indicator relative to MA 100. MACD indicator relative to its current and zero values. The CCI indicator relative to its current and zero values.

Expert Advisors
Here we will develop two EAs. As an example, we will use the values of the distances between indicators. The first one is implemented for optimization and selection of parameters. The second one is meant for trading using the results obtained from the first one. I have already considered this approach in my previous articles. This method helps sorting through and using all available optimization results in trading. For example, we got 50 good results during optimization. As you might imagine, installing an EA on 50 charts is not very convenient. Therefore, we will use all the results simultaneously with the help of the second EA.
Find out more about the method in my article "Experiments with neural networks (Part 3): Practical application"
I will provide the main code of the first EA for optimization below and describe what we passed to the perceptron:
The main code for opening positions.
//SELL++++++++++++++++++++++++++++++++++++++++++++++++ if((perceptron1()<-Param) && (CalculatePositions(symbolS1.Name(), Magic, POSITION_TYPE_SELL, EAComment)==0) && (SpreadS1<=MaxSpread)) { OpenSell(symbolS1.Name(), LotsXSell, TP, SL, EAComment); } //BUY++++++++++++++++++++++++++++++++++++++++++++++++ if((perceptron1()>Param) && (CalculatePositions(symbolS1.Name(), Magic, POSITION_TYPE_BUY, EAComment)==0) && (SpreadS1<=MaxSpread)) { OpenBuy(symbolS1.Name(), LotsXBuy, TP, SL, EAComment); }
Perceptron code.
- a1 is the distance between the MA1 indicator on the current candle and the candle in the Candles parameter.
- a2 is the distance between the MA100 indicator on the current candle and the candle in the Candles parameter.
- a3 is the distance between the CCI indicator on the current candle and the candle in the Candles parameter.
- a4 is the distance between the StdDev indicator on the current candle and the candle in the Candles parameter.
The Candles parameter in this case was not optimized and had a value of 8.
//+------------------------------------------------------------------+ //| The PERCEPRRON - a perceiving and recognizing function | //+------------------------------------------------------------------+ double perceptron1() { double w1 = x1 - 10.0; double w2 = x2 - 10.0; double w3 = x3 - 10.0; double w4 = x4 - 10.0; double a1 = ((ind_In1S1[0]-ind_In1S1[Candles])/PointS1); double a2 = ((ind_In2S1[0]-ind_In2S1[Candles])/PointS1); double a3 = (ind_In3S1[0]-ind_In3S1[Candles]); double a4 = (ind_In4S1[0]-ind_In4S1[Candles]); return (w1 * a1 + w2 * a2 + w3 * a3 + w4 * a4); }
Here I will provide all the parameters for optimization and testing so as not to repeat them further in the text:
- Forex market;
- EURUSD;
- Timeframe: H1;
- Indicators: MA 1 SMA CLOSE, MA 200 SMA CLOSE, CCI 42, StdDev 60.
- Stop Loss and Take Profit, 400 and 830;
- Optimization and test mode "1 Minute OHLC" and "Maximum Profit". Our EA initially works at M1 open prices. Here we will use the "Maximum Profit" mode as an experiment;
- Optimization range 1 year. From 2021.10.10 to 2022.10.10. 1 year is not some kind of criterion. You can try more or less on your own;
- Forward testing range is 1 year. From 2022.10.10 to 2023.10.10;
- In forward testing, the first 50 best optimization results were used simultaneously;
- Initial deposit 10000;
- Leverage 1:500.
Optimization settings are provided in the screenshot below:
The optimization results are shown in the screenshots below:
After optimization is completed, generate a file in CSV format using Excel. Let me remind you that we take the first 50 best results. Paste the resulting file into the code of the second EA for testing. It will look as follows in the code.

I will also provide the code for the second trading EA. As you can see, we go through all the values obtained during optimization in the loop and compare them with the current results of the perceptron execution. If the values match, a corresponding buy or sell position is opened. The limit on the number of simultaneously open positions is controlled by the MaxSeries parameter and the CalculateSeries function, which calculates positions by comments.
for(int i=1; i<=(ArraySize(EURUSD)/8)-1; i++) { comm=(EURUSD[i][0]+EURUSD[i][1]); x1=(int)StringToInteger(EURUSD[i][2]); x2=(int)StringToInteger(EURUSD[i][3]); x3=(int)StringToInteger(EURUSD[i][4]); x4=(int)StringToInteger(EURUSD[i][5]); Param=(int)StringToInteger(EURUSD[i][6]); //SELL++++++++++++++++++++++++++++++++++++++++++++++++ if((NewOpen==true) && (CalculateSeries(Magic)<MaxSeries) && (perceptron1()<-Param) && (CalculatePositions(symbolS1.Name(), Magic, POSITION_TYPE_SELL, EAComment+" En_"+comm)==0) && (SpreadS1<=MaxSpread)) { OpenSell(symbolS1.Name(), LotsXSell, TP, SL, EAComment+" En_"+comm); } //BUY++++++++++++++++++++++++++++++++++++++++++++++++ if((NewOpen==true) && (CalculateSeries(Magic)<MaxSeries) && (perceptron1()>Param) && (CalculatePositions(symbolS1.Name(), Magic, POSITION_TYPE_BUY, EAComment+" En_"+comm)==0) && (SpreadS1<=MaxSpread)) { OpenBuy(symbolS1.Name(), LotsXBuy, TP, SL, EAComment+" En_"+comm); } }
//+------------------------------------------------------------------+ //| Calculate Positions | //+------------------------------------------------------------------+ int CalculateSeries(ulong mag) { int total=0; string com=""; for(int i=PositionsTotal()-1; i>=0; i--) { if(position.SelectByIndex(i)) { if(position.Magic()==mag) { if(com!=position.Comment()) { com=position.Comment(); total++; } } } } //--- return(total); }

Working with ONNX models in float16 and float8 formats
Data formats used to represent machine learning models play a crucial role in their effectiveness. In recent years, several new types of data have emerged, specifically designed for working with deep learning models. In this article, we will focus on two new data formats that have become widely adopted in modern models.
Neural networks made easy (Part 60): Online Decision Transformer (ODT)
The last two articles were devoted to the Decision Transformer method, which models action sequences in the context of an autoregressive model of desired rewards. In this article, we will look at another optimization algorithm for this method.
Quantization in machine learning (Part 1): Theory, sample code, analysis of implementation in CatBoost
The article considers the theoretical application of quantization in the construction of tree models and showcases the implemented quantization methods in CatBoost. No complex mathematical equations are used.
Developing a Replay System (Part 28): Expert Advisor project — C_Mouse class (II)
When people started creating the first systems capable of computing, everything required the participation of engineers, who had to know the project very well. We are talking about the dawn of computer technology, a time when there were not even terminals for programming. As it developed and more people got interested in being able to create something, new ideas and ways of programming emerged which replaced the previous-style changing of connector positions. This is when the first terminals appeared.
