OK thanks for the insight. I noticed the file size does not change though, even if I train the NN on an optimization run of 10,000 passes. Shouldn't the file grow as the NN is built from many passes?


Why would the file need to grow??? The network size is not changing only the connections weights are being adjusted.

OK I am beginning to understand. So, do you think a NN trained via an optimization run of 10,000 passes is better trained than an NN trained via 1 single pass?

Well, I should mention that I had this problem running the FIXED version of the EA. When I run the original version, I do get different and better results for the test period. What is it about the fixed version that is not working for the test period?
Both versions are working yet the skewed version is performing better due to the trend. However this article is not about how to make a best profitable EA but how to use NN (namely FANN) in MQL4. This is just an example of application of NN however there's plenty of other applications (price forecasting, pattern recognition, reinforcement learning and so on). Try to find your best approach :)

Hi Emsi!


You said "However this article is not about how to make a best profitable EA but how to use NN (namely FANN) in MQL4."


I got your point, so: can you look to my questions in this article about how to use your article to be creative in

example by modifying your MACD EA with a MACD+MA EA?


I mean that if you help me/us to understand how add another "indicator" in your Article's EA, not just MACD

but MACD+MA i.e., it woulbe be very helping in order to understand how to apply new stuff with the use of FANN.


I hope you can help me to my questions, because something is still not clear to me in your EA (difficult to understand).


In particular: how to modify your EA in order to work not only with MACD but with MACD+MA ??

And if you want give us this one: how to modify your EA in order to work it with MA instead of MACD

(you can took the MA & MACD from the MT4 EAs samples).


Thanks very much. I hope you reply me.

Hi All,


I initially tried to use FXPro broker MT to test this, but I got totally different results. So I thought I would follow exactly what the author is saying.


Step 1. Installed InterbankFX

Step 2. Downloaded Data from Metaquote server after going to Tools->History Center

Step 3. Changed NeuroFilter=false,SaveAnn=false and AnnsNumber=0 in NeuroMACD and compiled.

Step 4. Used time period 2007.12.31 to 2009.01.01 for testing(time period M5). EURUSD


Attached screen shot of the result.


Why do I get different result?


I then changed NeuroFilter=false,SaveAnn=true and AnnsNumber=16 and then ran the testing to save the values.


After that I changed NeuroFilter=true,SaveAnn=false and AnnsNumber=16, and I got the same result as before. No effect of NN. Am I doing anything wrong?


I have read this article several times, and I am not sure where I am going wrong.


Thanks

Arnab

You definitely should read the article more carefully. It clearly states: "I used the data from Alpari, converted to M5 time frame." :)

I am still getting:

Any solution?

You have follow the installation process properly as mentioned in the article and it works. Close MT and restart.

I had the same issues and I followed the instructions and it worked.

The link that you gave me to download Alpari data, gives instruction on how to download the historical data. Thats what I followed. I do remember that some time back Alpari used to provide data in their website which is no longer available.


But if I consider the fact that I use some different data, how can I get same result with and without neuro filter? I did train the network and save the result before using neuro filter. Thats where I have been banging my head to find out.

This is just the most helpful, useful, well written, article I have come across in a long time. Thank you very much Emsi.

I am trying to run NeuroMACD-fixed as part of my process of understanding the article in detail, but always cop an abort (details below). Can anyone please tell me the cause of this abort. This is all I get:

Hello


Thanks about this great topic.

I am trying to test the EA on Strategy tester but I always get error 126 (cann't load library Fann2MQL.dll)

I made sure all files in the correct place and all setting are correct, I can use another EA with dll file without this error but this EA I cann't.


Can someone help me?

Thanks
