I'm in the process of putting these symbols/indicators to use but am stumped as to what these calculated symbols mean...

NASDAQ 3RD MKT ISSUES TOTAL ---what's the Nasdaq 3rd market?
NASDAQ COMB ISSUES TOTAL ---which issues are being combined?
NASDAQ NCM ISSUES TOTAL ---what's Nasdaq NCM ?
NASDAQ NGM ISSUES TOTAL ---what's Nasdaq NGM?
NASDAQ NGSM ISSUES TOTAL ---what's Nasdaq NGSM?

NYSE_ALT ISSUES TOTAL ---what's NYSE_ALT?

I really think your calculated symbols have a LOT of use but can someone put up some detailed description of what is really being calculated and the source of the input data, please?

Thank you very much!

Here is the info I got from our market data group. Unfortunately there doesn't appear to be anywhere we have these defined. I'll add that as a suggestion we add in the future.

IIOT.Z – OTC is the 3rd market

IIOT.Z = NASDAQ 3rd MKT Issues Advances (IIOA.Z) + NASDAQ 3rd MKT Issues Declines (IIOD.Z) + NASDAQ 3rd MKT Issues Unchanged (IIOU.Z)

IIQT.Z – The NGM, NCM and NGSM issues are being combined.

IIQT.Z = IIST.Z + IIMT.Z + IIGT.Z = IIQT.Z

IIST.Z – NASDAQ NCM is the NASDAQ Capital Market

IIST.Z = NASDAQ NCM issues Advances (IISA.Z) + NASDAQ NCM issues Declines (IISD.Z) + NASDAQ NCM issues Unchanged (IISU.Z)

IIMT.Z – NASDAQ NGM is the NASDAQ Global Market

IIMT.Z = NGM issues Advances (IIMA.Z) + NASDAQ NGM issues Declines (IIMD.Z) + NASDAQ NGM issues Unchanged (IIMU.Z)

IIGT.Z – NASDAQ NGSM is the NASDAQ Global Select Market

IIGT.Z = NGSMM issues Advances (IIGA.Z) + NASDAQ NGSM issues Declines (IIGD.Z) + NASDAQ NGSM issues Unchanged (IIGU.Z)

IIAT.Z - NYSE_ALT ISSUES TOTAL - NYSE_ALT is the new name for AMEX.
