Hi again.
I think you may be trying to treat as arrays some items whose typeof() is number.
Below is a section of the code with a few extra printf() statements, showing that, for example, nbuy_ is a number, not an array.
Despite this, later notation such as:
nbuy_[i] = 1;
is silently accepted.
I think that to get the results you want may require very careful attention to types, and possibly a different idiom than you are using.
There may be little help in that generalization, but I've not personally written/tested AFL ala your example, so I don't have a ready-made "solution" available to offer. (Others might.)
-----------
//filter the raw signals
nBuy_ = nSell_ = nShort_ = nCover_ = 0; // make sure all arrays are set empty
printf( "\ntypeof(nBuy_): " + typeof(nBuy_) ) ;
printf( "\ntypeof(Buy_): " + typeof(Buy_) ) ;
printf( "\nAfter initialization: \n" ) ;
printf( "nBuy_= %g nSell_= %g\n", nBuy_, nSell_ );
printf( "nShort_ = %g nCover_= %g\n", nShort_, nCover_ );
inBuy = inShort = 0;
vinBuy = vinShort = 0;
eprice = 0; //
veprice = 0; //
branch = 0;
printf( "\ntypeof(inBuy): " + typeof(inBuy) ) ;
printf( "\ntypeof(branch): " + typeof(branch) ) ;
