That's why it's advisable to set aside a third segment for validation, as was discussed above.
List of the best Neural Networks mt4 indicators of this page are:
However, one thing should be mentioned. Lets take another look at one of the charts: We can see, that winning and loosing trades are going in series. This certainly can be used to improve out results in one of two ways. Of course, this approach will not work, if we have series of loosing trades, with single winning trade between them, so it is necessary to do a careful study of the profit curve. This approach is an example of money management strategy, and it can improve some trading systems dramatically.
The fact that our system is sometimes working and sometimes does not, means that there is a factor or few factors unaccounted for. We need to look for these factors, and to adjust the system, for example, by adding an extra indicator, or by modifying the exixting one.
For example, if our system is profitable only when the price goes up, all we need to do is to add a condition: This approach can help a lot sometimes, however, it may require changing the code a bit. It is also possible, as I already mentioned, that the indicator is not good enough for a job. What if the system works fine while the range is between and points, and does not work when it is larger it means, the system does not work well, when the price moves too fast.
Then we need to change the indicator, to compensate for a speed of a price change, and MAYBE our results will improve. Once again, this is beyond the scope of this text. Finally, this system is too risky, as it uses very large value for stop loss, so again, it is just an example.
As Cortex is just a simulator, it cannot be used for trading in a real time. Getting weights of the NN Of course, it is possible to use the "run by timer" feature, and to perform file input and output, so that Cortex gets new quotes from the file, and writes results to the file.
The Trading Platform you use will read the results, use them to trade, and then, as new quotes become available, write them to file. This is not a very good approach. It is clumsy, and it can be error prone. Another approach is to use Cortex API. The third approach uses DDE and ActiveX, but as Cortex does not provide this kind of functionality, it cannot be used. But again, it is an extra layer of complexty, so the current approach is still better. The solution we suggest is to use ONLY scripting language of the trading platform of your choice.
First of all, we need to create the NN and to teach it. We did it in the chapters above, the result is the file with. In the following chapters we are going to: This is not a promotion, and if you prefer other platforms, use them. The code, responsible for creating and teaching the NN is commented in the script below.
When you run it for the first time, you need to uncomment it, of course. After that, you don't need to recreate the same NN over and over again, so if you want to run the script for the second time, you may want to set comments back again. Exporting NN weights The next step is to export weights of the NN to the scripting language of a trading platform of our choice.
To smooth over these differences, data were obtained from both platforms, and the strategies were built over both data series simultaneously. The best strategies were therefore the ones that worked well on both data series despite any differences in the data.
The data settings used in Builder are shown below in Fig. Other bar sizes or markets would have served just as well. I was only able to obtain as much data through my MT4 platform as indicated by the date range shown in Fig. Both data series were included in the build, as indicated by the checkmarks in the left-hand column of the Market Data table.
Market data settings for building a forex strategy for MetaTrader 4 and TradeStation. Another potential problem when targeting multiple platforms is that Builder is designed to duplicate the way each supported platform calculates its indicators, which can mean that the indicator values will be different depending on which platform is selected.
To avoid this possible source of discrepancy, any indicators that evaluate differently in MetaTrader 4 than in TradeStation should be eliminated from the build, which means the following indicators should be avoided:. All other indicators that are available for both platforms are calculated the same way in both platforms.
TradeStation includes all of the indicators that are available in Builder, whereas MetaTrader 4 does not. Therefore, to include only indicators that are available in both platforms, the MetaTrader 4 platform should be selected as the code type in Builder. That will automatically remove any indicators from the build set that are not available for MT4, which will leave the indicators that are available in both platforms.
Additionally, since I noticed differences in the volume data obtained from each platform, I removed all volume-dependent indicators from the build set. Lastly, the time-of-day indicator was removed because of differences in the time zones between data files. The indicators removed from consideration for the reasons discussed above are shown at the top of the list.
The remaining indicators, starting with "Simple Mov Ave", were all part of the build set. Indicator selections in Builder, showing the indicators removed from the build set. The evaluation options used in the build process are shown in Fig.
As discussed, MetaTrader 4 was selected as the code output choice. After strategies are built in Builder, any of the options on the Evaluation Options tab, including the code type, can be changed and the strategies re-evaluated, which will also rewrite the code in whichever language is selected. This feature was used to obtain the TradeStation code for the final strategy after the strategies were built for MetaTrader 4.
To create stop-and-reverse strategies, all exit types were removed from the build set, as shown below in Fig.
All three types of entry orders -- market, stop, and limit -- were left as "consider", which means the build process could consider any of them during the build process. Order types selected in Builder to create a stop-and-reverse strategy. To add a neural network to the strategy, it's only necessary to select the option "Include a neural network in entry conditions" on the Strategy Options tab, as shown below in Fig. The neural network settings were left at their defaults. The latter is necessary to enable the entry order to exit the current position on a reversal.
All other settings were left at the defaults. Strategy options selected in Builder to create a hybrid strategy using both rule-based and neural network conditions. The evolutionary nature of the build process in Builder is guided by the fitness , which is calculated from the objectives and conditions defined on the Metrics tab, as shown below in Fig. The build objectives were kept simple: More emphasis was placed on the build conditions, which included the correlation coefficient and significance for general strategy quality, as well as the average bars in trades and the number of trades.
Initially, only the average bars in trades was included as a build condition. However, in some of the early builds, the net profit was being favored over the trade length, so the number-of-trades metric was added. The specified range for the number of trades between and is equivalent to average trade lengths between 15 and 30 bars based on the number of bars in the build period. As a result, adding this metric put more emphasis on the trade length goal, which resulted in more members of the population with the desired range of trade lengths.
Build objectives and conditions set on the Metrics tab determine how the fitness is calculated. The "Conditions for Selecting Top Strategies" duplicate the build conditions except that the top strategies conditions are evaluated over the entire range of data not including the validation segment, which is separate , rather than just over the build period, as is the case for the build conditions.
The top strategies conditions are used by the program to set aside any strategies that meet all the conditions in a separate population. The final settings are made on the Build Options tab, as shown below in Fig. The most important options here are the population size, number of generations, and the option to reset based on the "out-of-sample" performance. The population size was chosen to be large enough to get good diversity in the population while still being small enough to build in a reasonable amount of time.
The number of generations was based on how long it took during a few preliminary builds for the results to start to converge. Build options include the population size, number of generations, and options for resetting the population based on "out-of-sample" performance. This value was chosen based on preliminary tests to be a high enough value that it probably would not be reached.
