Rounding Up/Down???
« on: September 25, 2015, 08:57:35 PM »

How do you guys round up/down, i have no idea

Here is an example of what i have found and what i would do is this wrong? What would you do in this case?

$100

Odd   Stake   Return
1.7   60.45   102.77
4.33   23.73   102.75
6.5   15.81   102.77

so if you round up/down 60+25+15=100

60 x 1.7= 102
25 x 4.33 = 108.25
15x 6.5 = 97.5 a loss!!!!

ok so there 6.5 and the outcome might not happen ,but it COULD and this is basically gambling or would you call this minimizing loss???

What would you do with these odds??

Any other examples welcomed

Thanks

u have two things going against u in this example

1-not having a sharp involved   -  u dont need to round in sharps, u can ever use .XXX
2-the total amount is small   -   put those odds in a calculator and set the total amount to 1k  and ull see its way more easier to round up

If two wrongs don't make a right, try three.

First reply to a post, hopefully this helps.

If you are worried about rounding, why not always place a bet between a Sharp and a Soft bookie. The only one that will worry about the round odds are the Soft bookies. In this case you can just use a bit of maths to work it out so you aren't loosing percentage on your arb:

Example:

2.3% arb

Player 1: Sharp odds = 1.83
Player 2: Softy odds  =  2.32

So why not decide the bet at the softy, let's say $100. Then bet 100 * (2.32/1.83) = $126.78 at the Sharp.

Now if you want to do it on a 3-way bet, You need to have 2 legs at a Sharp for this to work, otherwise you will get 2 non-rounded values and one of the softies will get the rounding error, but here is the maths on your numbers:

Bookie    Odd               Stake                          Return
Sharp     1.7     100*(6.5/1.7)   =   $382.35    $650.00
Sharp     4.33   100*(6.5/4.33) =   $150.12    $650.00
Softy      6.5     $100                                      $650.00

So Like everyone said above, depends on sharp vs softy.

Otherwise, just put it in excel and play with =mround(number, multiple) and see which set of rounded numbers gives you the closest percentage to the arb.
