Subject: NYSE closing auction
Message: Hi,

I am trying to identify closing auctions for NYSE listed stocks. I know trade with condition code "L" is official NYSE closing auction, but in following example: GM 11/06, I see two prints at the closing price:

2008.11.06 GM 16:01:11.063 4.8 96600 0 N
2008.11.06 GM 16:01:19.675 4.8 456000 1 L N

What's the significance of each print? What is the total auction volume?

Another example: IBM 11/06, also two prints at the closing price, but none of them has code "L"

2008.11.06 IBM 16:01:14.424 85.15 29800 0 N
2008.11.06 IBM 16:01:18.445 85.15 824200 1 N

What's the complete logic to get NYSE closing auction data?

Thanks,
Peter
