  • When did the NYSE/AMEX introduce stock symbols for each stock?

    I'm trying to do a bit of research on the use of symbols on each exchange.

    Does anyone know when the NYSE/AMEX introduced stock symbols for each stock?

    Does anyone know if the original "ticker tapes" had either symbols or an abberviated company name, or something else? (Perhaps you might have read an old trading book that talked about it?)

    Cheers,

    Richard.

  • Is my RMS AC Clamp Meter faulty?

    I have a RMS AC Clamp Meter and have set it to AC mode and Current mode as shown at http://www.altronics.com.au/index.asp?area=item&id...

    When I open the clamp and place it around an AC (240 volt) power cable attached to a working 1000 watt heater, I get a reading of around 0.5A. Indeed when it's not clamped to anything I get a reading of around 0.5A. I was expecting a reading of around 4 amps. Apparently the unit has an accurate of +-(3.0% + 0.6A) at a range of 0 to 70A. The unit itself is rated to 600A and has a display that can show 0.000-400.0 A when in the 400A position.

    Given the above detail, is my RMS AC clamp meter faulty?
