 ## Notes
 
-* Quotes are pulled from Yahoo finance which, like other financial news sources, provides delayed stock quotes as opposed to real-time quotes - information in `ticker` is appropriate for casual use cases such as position tracking and price watching but not for active trading where up to the minute/second pricing matters
+* **Real-time quotes** - Quotes are pulled from Yahoo finance which may provide delayed stock quotes depending on the exchange. The major US exchanges (NYSE, NASDAQ) have real-time quotes however other exchanges may not. Consult the [help article](https://help.yahoo.com/kb/SLN2310.html) on exchange delays to determine which exchanges you can expect delays for or use the `--extra-info-exchange` flag to include timeliness of data alongside quotes in `ticker`.
