My broker software reports 2 different numbers for "volume" and "number of trades". However, if I look on investopedia it lists "volume" to be the number of trades. The volume number is usually 2-3 digits larger than the other number. What do these two different numbers mean?

For stocks, volume is the number of shares traded. A trade can be (and almost always is) for multiple shares, and is usually a multiple of 100, which is why the volume is 2-3 digits more than the number of trades.

I don't see where your link defines "volume" as "number of trades".

  • For me the page lists as the first sentence: Trading volume is the total number of shares of a security that were traded during a given period of time.. In my broker's documentation it has a code v for volume and then another piece of information it calls n which it says are the number of trades.

    "Trading volume is the total number of shares of a security..." One trade can be for 100 (or 5, or 10,000) shares

  • Your answer makes perfect sense as to why both are integers.
