Yahoo Finance options volume data mismatch

  1. Does anyone exactly what the issue here could be? I've checked the Yahoo data against my own broker data feeds along with CBOE and google, all of them contradict what Yahoo is showing.

    Here's an example.

    Yahoo:
    35.00 NQ150117C00035000 1.32 0.00 1.20 1.80 2,000 4,243

    CBOE:
    NQ1517A35-E 0.95 0.0 1.20 1.80 0 4243

    Everything else is showing 0 for volume. Any ideas?
