Aleksey Vyazmikin:

Please upload the log after the CB_svod.csv script is running.

Please find attached,

I also attache the CB_Bat set file

There is no error in the log. Send the file in the zip archive "output_test". I assume that there are no rows with a probability greater than 0.5. Very small sample.

Cols(2413) Rows(289) - test.

From these results, we need to select values with a high custom parameter — preferably 35% and higher, with a number of trades 15000 and more (the more the better). Optionally, other econometric variables can be analyzed.

I uploaded the whole Rezultat folder:

About sample size: Optimization was done on EURUSD 2016.01.01 - 2020.01.01. The highest trade number optimization which had more or less flat balance curve had around 1400 trades:

"Rezultat\RS_32\result_4_Test_CB_Setup_0_000000000" Probability<0.5, but one >0.5. What is the balance for the test sample?

Line of balance is good, but in this case it is important a greater number of transactions. The more examples, the more knowledge about the market.

I am not sure you are asking for the result for RA_32 from the CB_Svod.csv file (I also noticed that this was the only row which had all positiveresults): But still the mqh model was not generated for this. Do you have an idea why? Thanks for all the help.

Now it is obvious that the script is working correctly. Models are created only those that have passed the filter, which by default is 3000 points. Lower this threshold in the script settings.

input double Filter=3000;//Minimum balance for copying and saving the chart

Thanks! I will try further from the optimization part.

I am glad that You decided to reproduce the entire process described in the article. Good luck!
