I found this article in the codebase:
"HOW TO EVALUATE THE EXPERT TESTING RESULTS"
It works fine for testing ONE run, but if I will do an optimization, than in the text-File shows only the last result (not for the different optimization values of an variable) :-(
I've tried to put this part in the OnTester()-Function
So how can I realize that after EACH automatical run of my EA the result will be written in an text-file?
Be careful with this idea!
If the tester is optimizing it will test and write according to your wish e.g. in genetic mode between 8'000 and 19'000 results.
~20'000 * 25 lines will create 500'000 lines - you can't manage this. Even editors will probably refuse to open such a file - toooo big!
Write only one line per pass into a csv-file. Use OnTester() for this.
I thought about this and in the first step I only write the values from the variables an the results in ONE file and for each result the summary, not each trade.
I also don't want to optimize more than about 100-200 results each time.
I insert a function to write into a text-file in the OnTester-Function but it never works whether on testing or on optimizing!? (But the same code works, if I put it into the init function.
To ad a line you have to do (without checking for errors - you'll find them in the journal tab anyway):
string row = StringFormat("%.5f;...\n",var1,...);
int fH = FileOpen(fName,FILE_READ|FILE_WRITE);
FileWriteString(fH, row, StringLen(row) );
Otherwise you have to create at every pass a new file name - not to overwrite the existing ones.
