It means an investor(S) in Montreal invested $30,000 in the TDC. It's a puny volume. Have you become accustomed to such small volumes that 70,000 shares seems "large"?
We are so down inthe dumps right now that just one new investor makes a noticeable change in volume.
Go back to your day job, today is not our day. When there is over a million shares traded, then something is goingon.
