Okay, you probably have a ticker somewhere with only 1 bar in it, since you're running it on all symbols. Try running on just one symbol that you know has plenty of data.

sorry for not giving error message:

Ln:7,col:24 error 10. subscript out of range. you must not access array elements outside 0..(barcount-1)range.

Terry <MagicTH@xxxxxxxxxxx> wrote:

Sometimes in loop code you need to initialize the entire array first, but I didn’t mention this since it was working for me. Also, you didn't say what the error message was.

function IIR2( input, f0, f1, f2 )

{

    Result = 0;

   result[ 0 ] = input[ 0 ];

  result[ 1 ] = input[ 1 ];//<---- getting error

etc…
