We should specify the number of steps, for which we are to build distribution and calculate the necessary values. Then we should inform the system of the step size in points and whether we need visualization of steps. Steps are to be visualized by drawing on the chart. I have selected the indicator style in a separate window displaying the neutral distribution and the current situation.

There are two lines, although it would be good to have the third one. Unfortunately, the indicators capabilities do not imply drawing in a separate and main windows, so I have had to resort to drawing. Now the code is made compatible with MQL4 as much as possible and we are able to turn it into an MQL4 analogue quickly and easily.

Additionally, we will need a point to count the next step from. The node stores data about itself and the step that ended on it, as well as the boolean component that indicates whether the node is active. Only when the entire memory of the node array is filled with real nodes, the real distribution is calculated since it is calculated by steps.

No steps — no calculation. Further on, we need to have the ability to update the status of steps at each tick and carry out an approximate calculation by bars when initializing the indicator. Next, describe the methods and variables necessary to calculate all neutral line parameters.

Its ordinate represents the probability of a particular combination or outcome. I do not like to call this the normal distribution since the normal distribution is a continuous quantity, while I build the graph of a discrete value. Besides, the normal distribution is a probability density rather than probability as in the case of the indicator. It is more convenient to build a probability graph, rather than its density. All these functions should be called in the right place. All functions here are intended either for calculating the values of arrays, or they implement some auxiliary mathematical functions, except for the first two.

They are called during initialization along with the calculation of the neutral distribution, and used to set the size of the arrays. Next, create the code block for calculating the real distribution and its main parameters in the same way. Here all is simple but there are much more arrays since the graph is not always mirrored relative to the vertical axis. To achieve this, we need additional arrays and variables, but the general logic is simple: calculate the number of specific case outcomes and divide it by the total number of all outcomes.

This is how we get all probabilities ordinates and the corresponding abscissas. I am not going to delve into each loop and variable. All these complexities are needed to avoid issues with moving values to the buffers. Here everything is almost the same: define the size of arrays and count them. Next, calculate the alpha and beta trend percentages and display them in the upper left corner of the screen. CurrentBuffer and NeutralBuffer are used here as buffers.

For more clarity, I have introduced the display on the nearest candles to the market. Each probability is on a separate bar. This allowed us to get rid of unnecessary complications. Simply zoom the chart in and out to see everything. The CleanAll and RedrawAll functions are not shown here. They can be commented out, and everything will work fine without rendering. Also, I have not included the drawing block here.

You can find it in the attachment. There is nothing notable there. The indicator is also attached below in two versions — for MetaTrader 4 and MetaTrader 5. I have developed and seen plenty of strategies. In my humble experience, the most notable things happen when using a grid or martingale or both. Strictly speaking, the expected payoff of both martingale and grid is 0. Do not be fooled by upward-going charts since one day you will get a huge loss.

There are working grids and they can be found in the market. They work fairly well and even show the profit factor of This is quite a high value. Moreover, they remain stable on any currency pair. But it is not easy to come up with filters that will allow you to win. The method described above allows you to sort these signals out. The grid requires a trend, while the direction is not important. Martingale and grid are the examples of the most simple and popular strategies.

However, not everyone is able to apply them in the proper way. Self-adapting Expert Advisors are a bit more complex. They are able to adapt to anything be it flat, trend or any other patterns. They usually involve taking a certain piece of the market to look for patterns and trade a short period of time in the hope that the pattern will remain for some time. A separate group is formed by exotic systems with mysterious, unconventional algorithms attempting to profit on the chaotic nature of the market.

Such systems are based on pure math and able to make a profit on any instrument and time period. The profit is not big but stable. I have been dealing with such systems lately. This group also involves brute force-based robots. The brute force can be performed using additional software. In the next article, I will show my version of such a program. The top niche is occupied by robots based on neural networks and similar software. These robots show very different results and feature the highest level of sophistication since the neural network is a prototype of AI.

If a neural network has been properly developed and trained, it is able to show the highest efficiency unmatched by any other strategy. As for arbitration, in my opinion, its possibilities are now almost equal to zero. I have the appropriate EAs yielding no results. Someone trades on markets out of excitement, someone looks for easy and quick money, while someone wants to study market processes via equations and theories. Besides, there are traders simply having no other choice since there is no way back for them.

I mostly belong to the latter category. With all my knowledge and experience, I currently don't have a profitable stable account. I have EAs showing good test runs but everything is not as easy as it seems. Those striving to get rich quickly will most probably face the opposite result.

After all, the market is not created for a common trader to win. It has quite the opposite objective. However, if you are brave enough to venture into the topic, then make sure you have plenty of time and patience. The result will not be quick. If you have no programming skills, then you have practically no chance at all.

I've seen a lot of pseudo traders bragging about some results after having traded deals. In my case, after I develop a decent EA, it may work one or two years but then it inevitably fails In many cases, it does not work from the start.

Of course, there is such thing as manual trading, but I believe it is more akin to art. All in all, it is possible to make money on the market, but you will spend a lot of time. Personally, I don't think it is worth it. From the mathematical perspective, the market is just a boring two-dimensional curve. I certainly do not want to look at candles my entire life.

I believe that the Grail is more than possible. I have relatively simple EAs proving it. Unfortunately, their expected payoff barely covers the spread. I think almost every developer has strategies confirming this. The Market has plenty of robots that can be called Grails in all respects. But making money with such systems is extremely difficult as you need to fight for each pip, as well as enable spread return and partnership programs.

Grails featuring considerable profits and low deposit loads are rare. If you want to develop a Grail on your own, then it is better to look towards neural networks. They have much potential in terms of profit. Of course, you can try to combine various exotic approaches and brute force, bit I recommend delving into neural networks right away. Oddly enough, the answer to the questions of whether a Grail exists and where to look for one is quite simple and obvious to me after tons of EAs I have developed.

The first point is the most important here. If you have a profitable strategy regardless of whether it is manual or algorithmic , you will always want to intervene. This should not be allowed. Situations, in which profitable deals are less numerous than losing ones, exert a considerable psychological impact ruining a trading system. Most importantly, do not rush to win back your losses when you are in the red. Otherwise, you may find yourself with even more losses. Remember about an expected payoff.

It does not matter what the current position's equity loss is. The next important thing is a lot size you apply in your trading. If you are currently in profit, make sure to gradually reduce the lot. Otherwise, increase it. However, it should be increased only up to a certain threshold value.

This is a forward and reverse martingale. If you think carefully, you can develop your own EA based purely on lot variations. This will no longer be a grid or martingale, but something more complex and safe. Besides, such an EA may work on all currency pairs throughout the history of quotes. This principle works even in a chaotic market, and it does not matter where and how you enter. With proper use, you will compensate for all spreads and commissions, and with masterful use, you will come out with a profit even if you enter the market at a random point and in a random direction.

To reduce losses and increase profits, try to buy on a negative half-wave and sell on a positive half-wave. A half-way usually indicates the previous activity of buyers or sellers in the current market area, which in turn means that some of them have been market ones, while open positions will close sooner or later pushing the price in the opposite direction.

That is why the market has a wave structure. We can see these waves everywhere. A purchase is followed by a selling and vice versa. Also close your positions using the same criterion. Everyone's perspective is subjective. In the end, it all depends on you, one way or another. Despite all the disadvantages and wasted time, everyone wants to create their own super system and reap the fruits of their determination.

Otherwise, I do not see the point of delving into Forex trading at all. This activity somehow remains attractive to many traders including myself. Everyone knows how this feeling is called, but it will sound childish.

Use new possibilities of MetaTrader 5. MetaTrader 5 — Trading. Evgeniy Ilin. Introduction I am a developer of automatic strategies and software with over 5 years of experience. Why is it so challenging to find entry and exit points?

Market mechanisms and levels Let me tell you a little about pricing and powers that make the market price move. Mathematical description of the market What we see in the MetaTrader window is a discrete function of the t argument, where t is time. M4 — expected payoff when closing by a signal. P1 , P2 — probabilities of stop levels activation provided that one of the stop levels is triggered in any case.

P0[i] — probability of closing a deal with the profit of pr[i] provided that it has not triggered stop levels. PS[k] — probability of setting k th stop level option. MS[k] — expected payoff of closed deals with k th stop levels. M3[k] — expected payoff when closing by a stop order with k th stop levels. M4 [k] — expected payoff when closing by a signal with k th stop levels. P1 [k] , P2 [k] — probabilities of stop levels activation provided that one of the stop levels is triggered in any case.

P0[i] [k] — probability of closing a deal with pr[i] [k] profit, according to a signal with k th stop levels. MSp[k] — expected payoff of closed deals with k th stop levels. MSl[k] — expected payoff of closed deals with k th stop levels. M3p[k] — expected payoff when closing by a stop order with k th stop levels. M4p [k] — expected payoff when closing by a signal with k th stop levels.

M3l[k] — expected loss when closing by a stop order with k th stop levels. M4l[k] — expected loss when closing by a signal with k th stop levels. For a deeper understanding, I will depict all nested events: In fact, these are the same equations, although the first one lacks the part related to loss, while the second one lacks the part related to profit. The calculation application screenshot below clarifies this: It lists everything we need.

Writing a simple indicator Here I am going to transform my simple mathematical research into an indicator detecting market entry points and serving as a basis for writing EAs. Let's start from the indicator inputs. To describe the steps, we first need to describe the nodes. It remains to define what and where to call. This will look as follows. Below is the option with other inputs and window style. Review of the most interesting strategies I have developed and seen plenty of strategies.

Is it worth the hassle? Does the Grail exist and where to look for it? Tips for common traders All traders want three things: Achieve a positive expected payoff Increase profit in case of a profitable position Reduce loss in case of a losing position The first point is the most important here.

I am trying to give a more rigid definition to all these phenomena, since even a basic understanding of these matters and means of their quantification allows applying many strategies previously considered dead or too simplistic. The profit factor is the ratio of profit to loss.

The larger the ratio between MFE and MAE for a given currency pair, the more favorable is the outlook for a potential trade. Those parameters can be set independently by the mechanical trading system based on ME adjusted for volatility, as discussed later in this article. After determining the entry point and trade direction, the mechanical trading system calculates MFE and MAE values generally first at 10 bars beyond the entry price, then 15 bars beyond, then 20 bars beyond the entry price.

My simplest multicurrency trading strategy uses daily charts and relies on a combination of three price-based rules, and only a few parameters that use mathematical expectation to predict success. This system reverses the trade when the signal changes. Another parameter of this system is the stop-loss trigger which is set at a value just slightly more than the fifteen-day or twenty-day average true range ATR.

This value is updated each time a new signal is received in the same direction. This simple multicurrency forex trading system has shown decent results in real trading, and back-testing over a twenty-year period shows that it would have enjoyed profitable results for at least sixteen out of the twenty years tested.

It has shown a reward-to-risk ratio of about 1. Still, the drawdowns can be lengthy — The longest drawdown seen under back-testing was more than days. The ratio of profit-to-drawdown when using this strategy is similar to that of buying-and-holding stocks, and during back-testing the ratio was about 0. By knowing the average MFE and MAE values, a forex trader can program a multicurrency mechanical system to exit a trade at a profit target or stop-loss point determined by adding a calculated number of pips beyond the Maximum Favorable Excursion or Maximum Adverse Excursion values.

On average, in order to win over time the forex trading system must reach the profit goal more often than it touches the stop-loss exit level. For example, if my system is seeing an average MAE of 35 pips and an average MFE of 55 pips, there is a tradable opportunity. The profit target may be projected for 50 pips, which is 5 pips less than MFE, and the stop-loss exit can be set at 30 pips, which is 5 pips beyond the MAE.

The system determines the entry price plus or minus a percentage of the ATR that is workable according to the ME analysis. To have a large enough sample, I usually set the ATR to calculate the previous 15 or 20 time frames. So, if a trade moves in a favorable direction for 55 pips, and if the current ATR is 85 pips, the move is not reported as 55 pips; instead, the MFE is reported as In order to fine-tune forex trading results according to volatility, the mechanical trading system can set the profit targets and stop-loss points at varying levels.

Still, this system is likely to reach target profit levels more often than stop-loss levels, and winners should be larger as long as target profits are set larger than stop-losses. For all trades, the calculated number of pips for target profits and stop-losses is always based on volatility just at the moment of the trade, as reflected by the ATR. When a signal arises, the trading system checks the value of current ATR, then calculates the exact number of pips to reach target profit and stop-loss levels.

Using this system, my average trade duration is about 25 days. In summary, this basic multicurrency forex trading strategy takes advantage of a positive, high ME shared across the four major currency pairs. The entries, profit targets and stop-loss points are all based on ME.

Mathematical expectation predicts the likelihood that a forex trade will win A well-programmed EA can use ME tools to help build systems that work across multiple currency pairs. Calculating the mathematical expectation of success Mathematical Expectation ME is a statistic that measures the greatest temporary profit that a trade experienced the entire time it remained open.

Trading results This simple multicurrency forex trading system has shown decent results in real trading, and back-testing over a twenty-year period shows that it would have enjoyed profitable results for at least sixteen out of the twenty years tested. Risk management for multicurrency trading strategies using ME By knowing the average MFE and MAE values, a forex trader can program a multicurrency mechanical system to exit a trade at a profit target or stop-loss point determined by adding a calculated number of pips beyond the Maximum Favorable Excursion or Maximum Adverse Excursion values.

Volatility helps determine exit points for multicurrency trading As mentioned earlier, a mechanical trading system can easily use Average True Range ATR as a volatility-dependent tool to calculate MAE and MFE in order to set exit points.
