Calculations of combo bets - pro stuff

[benlaw]

2 questions basically.
I want to understand how my bookie compiles his combo odds and make sure he's not bluffing .

1. How do I put up a combo (accumulator) of - only positive american odds
- only negative american odds
- positive and negative odds together

2. How do I put up a combo (accumulator) of - solid numbers and quarters (like in over/under)
example : team-team 2.25 Over 1.93
team-team -0.75 Under 1.22
team-team 1 Over 1.51

how do I calculate the result - my winnings ?

About your first question, a person who knows the american style of odds can help you, i can't

About your second question, i think it is simple,

Winnings will be @1.93 x @1.22 x @1.51 * stake - stake

If you gonna take this combo for 100 euros for example, it is :

@1.93 x @1.22 x @1.51 * 100 - 100 = 255 euros profit

yep,
but what happens in the case of :

team-team 2.25 Over 1.93

and the game result is for example 1:1

that means i only half of the cash

how will that sun up with the rest of the combo ?

hm, nice question, i am facing this first time too.

Which is the bookie you bet this combo?

They should have some rules or explanations i think,
anyway too few bookies allows combos with half handicaps like 2.25, 1.25, 1.75, etc...

you allready tried to wager and the combo was accepted?

1. How do I put up a combo (accumulator) of - only positive american odds
- only negative american odds
- positive and negative odds together

You'll chance the odds to european odds and calculate the odds as you always do. With positive odds you'll add 100 and divide it by 100. For example +250=(250+100)/100=3.50

If negative the chance goes taking the negative mark out from the odd, adding 100 to the amount and dividing it by itself. For example -150=(150+100)/150=1.666....

2. How do I put up a combo (accumulator) of - solid numbers and quarters (like in over/under)
example : team-team 2.25 Over 1.93
team-team -0.75 Under 1.22
team-team 1 Over 1.51

If you bet over 2.25 half of your stake is on over 2 and other half on over 2.5, just like as in a single. No experience though but no reason it'd be different.
