Hey Guys,
Hoping anyone can still chime in on this problem. I got the following code to work. However, if my text file contains, say, 5,000 numbers (each on a separate line), the AFL only seems to recognize the first 2,988. I've tried different text files of varying sizes and it seems that for any files bigger than 3,000 numbers, the AFL only captures less than 3,000, e.g 2,843 ...
For smaller files, like 1650 numbers, the AFL captures all the numbers as it should.
Is there some limit in AmiBroker that is causing this? Or is there a flaw in this test code somewhere:
Count = 0;
if(Status("ActionEx") == actionExOptimizeSetup)
{
count = 0;
fh = fopen("c:\\TestExtractFile03.txt", "r");
if (fh)
{
while(!feof(fh))
{
StaticVarSet("Row"+NumToStr(Count,1.0,0), StrToNum(fgets(fh)) );
StaticVarSet("Count", Count);
Count++;
}
} else
{
printf("ERROR: file can not be found (does not exist)");
}
}
b = Optimize("b", 9, 1, Count, 1);
Count = StaticVarGet("Count");
for(a = 0; a < Count; a++)
{
Row = StaticVarGet("Row"+NumToStr(a,1.0,0));
printf("Row: %g\n", Row );
}
Buy = a == 12; // random buy/sell conditions for test purposes
Sell = a == 2;
