NBA 1st Quarter Lines Archive

I haven't seen such, but I'm told places like Don Best might have this.

I have never seen one.

But you can pretty well make up one of your own. They are pretty standardized. Check out The Greek for a few days. You'll see for example that a game lined at -10 generally will be -3 1Q/ -3 2Q/ -3 3Q/ -2 4Q.

I thought about Don Best too, but I can't find much of anything on Don Best related to archived odds.

That's very interesting. Thanks for that.

I'm fairly sure DB does not have archived quarter lines.

1st Q & 1st half seems like it can be derived from the game line, 2nd half lines need to be scraped from somewhere.

I've always wanted to get a db group together where some folks might share skills. I hate data scraping, and much prefer to model.

1Q: roughly estimated 1/3 of Game spread, far from accurate hence the +/- .5 spread margin..

There's a danger in using a formula to figure first quarter lines. First, the linemaker recognizes emotional situations and will jack a 1Q line up as much as a point and a half in a favorable handicapping situation, and then of course players collectively get it too and will sometimes move a 1Q line while the game line sits there still as a moose.

Disagree, but certainly willing to listen.

What sort of "emotional situation" have you seen or could envision that would jack up a 1Q line but not the game line?

I can't think of any that would not effect both.

A bad team plays a good team coming off a big game the night before...line will swing to accommodate the possibility of a flat start...or a team like Phoenix coming off a disappointing game playing someone they should beat...say game line is -10, 1Q line may be 3.5 or 4 by close. The game line is discounted relative to the 1Q because of the back door cover equity.

It also happens when there's a multi-year history of a certain bias, like the Portland 1Q home bias that Coach McMillan seems somehow to be able to conjure up down the stretch. I believe they're 19-19 ATS at home, but the market "knows" their by quarter chart in the context of the season flow and adjusts for it. Portland's 1Q Away record looks good, but so too is their game record--and so you don't find the same decided adjustments.

Does anyone know where archives of NBA 1st quarter lines can be found? I can find plenty of archives, but none with the 1st quarter.

I have 1Q lines back to the 1981-82 season...

No formulas...

My original NBA database (circa 2005-06 used formulas for the quarters) but I recognized quickly right around that time that quarter lines were getting more popular and I noticed that linesmakers were already making adjustments on 1Q lines during the season back then, so I researched for many years and used personal notes for lines I had in the late 80s through the 90s and now my new and improved database does not use formulas for the quarter lines...

brewers7, I am doing a master's thesis on correlations between past halftime and final NBA betting lines. Could you PM me on what you have available?

**mikeb75** · 10-19-12, 05:09 PM

brewers7, this site doesn't let me respond to PMs until I have 20 posts. Could you PM me your email?

**brewers7** · 10-19-12, 05:17 PM

Done...

**1qaz2wsx** · 10-24-12, 07:40 PM

Hi brewers7, I'm also doing some research into quarterly and halftime NBA data. Could you please also send me a PM? Thanks!

I see sportsdatabase has a 'quarter scores' search parameter now.
