Question about movement of spread odds & ML odds

[tonywayne]

I'm a relatively new bettor and I'm still trying to work out what it means when a spread underdog has negative odds. What is it telling us about the book's actual thoughts on who will win? Is it telling us something about public betting?

The example would be tonight's game, Baltimore @ Detroit. The Ravens are +7, but with -140 odds right now (Bovada). The Lions are -7 (+120). But then on the moneyline, the Ravens are +190 and the Lions are -230.

Bear in mind, the spread odds only 12 hours ago were Ravens +7 (-115), Lions -7 (-105). 6 hours ago it moved to Ravens +7 (-130), Lions -7 (+105).

Why are the spread odds moving, but the spread itself isn't budging? I've heard a few things about the books trying to dupe bettors into certain kinds of bets - is that what's happening here? I thought that if the public was dumping money one way, then the spread would move to slow it down.

Thanks guys. I appreciate any insight any of you might be able to provide...

the think tank sure misses justin7, this is for the newbie forum

you need to understand what +120 and -140 etc mean.

+120 means you bet 100 and you can win 120
-120 means you bet 120 and you can win 100

odds with + always show how much you can win if you bet 100
odds with - always show how much you can lose if you bet to win 100

you can use sites like oddsportal to watch the decimal odds to understand what odds actually mean

when you have a spread of +6.5/-6.5 with odds -110/-110 or -105/-105 or -115/-115 that is a 50-50% proposition. That means the bookmaker considers there is a 50% chance the underdog to lose by 7 points

If the bookmaker receives more bets on one side than the other you will see odds drop from -110 to -115 or -120 and the other side rise from -110 to +100 or something like that

I think what the OP was asking was how come the line didn't move to -6.5 (-110) instead of holding at -7 (-140).
Likely after moving from (-125) to (-130) etc.
Eventually the line was lowered to 6.5 & this after openning at -6.
By kick off the Lions were only favoured by 4.5. -4 at some books.

I don't really understand what the moneyline had to do with his question.
That's a completely different bet.

I don't really have an answer for this question but, I can answer your question about what it is telling us.
It's not telling us who the books think will win the game. It's a direct reflection of where the public's money is going, regardless of whether it's sharp money or punter's money, like mine!
