The number of stocks listed in nasdaq is 3.5k http://i.imgur.com/HhAubKE.png
but the number of stocks that your symbols lookup is showing is >63k. http://i.imgur.com/hUMtulT.png
how do i filter out the right symbols from mktsymbols_v2 zip file. the zip file matchs your website but there seems to be too much symbols for LSE and Nasdaq that dont align with the counts provided by the exchange.

The number 63,449 under NASDAQ that you see it the total number of Equities, Equity Option symbols, Indexes, OTC and Futures symbols.

You can drill further down by utilizing the Security Type field just below where you had chosen Filter by Exchange.

it still does not add up. I pulled all the Nasdaq info in a pivot table and you can see I don't get the right counts. Just tell me what doe these different column types mean?



I have exchange=Nasdaq
when I filter Equity, I get 19091 symbols. this is way too many for nasdaq

Equity is stock symbols.

Index is index symbols.

Money is money market symbols.

Mutual is mutual funds.

why do you hve 19k Nasdaq symbols in equity? it makes no sense when Nasdaq posts that they have 3.5 k symbols.

That number of 19,086 includes NCM, NGM, MGSM, OTCBB and OTC. The over the counter stocks account for more then 15,000

so which part of this accounts for the Nasdaq only. there are 3273 listed in their website
http://www.nasdaq.com/screening/companies-by-industry.aspx?exchange=NASDAQ. Should I just ignore OTC only or should I ignore any of the other ones NCM, NGM, MGSM?
I need better clarity as its your symbol list and I need to make it better.
I have similar issue with LSE symbols where the counts are greater than what is listed in LSE

If you utilize NCM, NGM and NGSM you will get the expected results for NASDAQ. You should omit OTC and OTCBB.

Unfortunately that number 23,304 that our symbol lookup is reflecting for London Stock Exchange (Equities) has Mutual Funds and Bonds intermingled.

This has been reported to our developers for resolution. Unfortunately there is not an ETA at this time.
