Mark, the file error is caused by the use of forward slashes rather than back slashes. The out of bounds error (on 6e) occurs because the index is keyed directly to price rather than something like index=p+offset to center price in the array; There's also a conceptual error that no one has mentioned, where the reserved word volume should be changed to ticks.
