The symbols are not looped over in any particular order. That if fails on the 39th or 40th try seems pretty consistent. File Attached: script_and_input.zip (downloaded 1226 times)

I just ran through your list of symbols making the above HTT request for each and the only two symbols that returned NO_DATA were NOVL and GENZ which no longer valid symbols (but were valid recent enough to not trigger an Invalid Symbol error).
