Each time the roughly 39th request returns no data, not even !E,NO_DATA
Sadly, my code can't seem to handle the return of absolutely nothing very well. |

Attached is my code and the symbols I am looping over.
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 1222 times) |

Also, strangely, it seems to fail the most with the symbol TSM.
I've spent all weekend trying to figure this out. |

Josh,
I'm not terribly familiar with perl but I believe that script just reads in your list of symbols and builds an HTT request to get tick data for May 20th between 09:30:00 and 16:00:00 for each symbol right? 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symbols making the above HTT request for each and the only two symbols that returned NO_DATA were NOVL and GENZ which no longer valid symbols (but were valid recent enough to not trigger an Invalid Symbol error). |

Thank you for your reply.
Using RequestIDs and a hash of filehandles seems to work. |
