hi guys,
    can anyone give me a steer on how I can factor in the probability of a middle landing when deciding whether to take a negative middle.

At the moment I have a blanket rule that applies to all situations - if the loss is greater than 1% of total stake then ignore.

But it has occurred to me that I should be trying to factor in the likelihood of the middle landing
  eg Totals
          O(3)  vs U(3.5)          in soccer

          O(174.5) vs U(175)        in volleyball

Even though the range between the two limits is 0.5 in both situations, it is obvious that there is a much better chance of the soccer middle
landing than the volleyball. Consequently I should be reckoning to accept greater losses as the likelihood of the middle landing is much greater.

So something like if loss is < 10% in soccer go for the middle, if loss is <1% in volleyball go for the middle.

I am wondering if there is a useful algorithm I can use.

Also is there something similar for handicaps (spreads)?

Just quick thought, its obvious that the factor is connected to statistic. Question is how many times in a long run will case A hit and how many times in long run will case B hit. If the middle cost less(in %) than its the potential win (in %) based on statistics. Than you have EV+ middle.

I agree with ajeto, it's all about stats.

If supposed that exactly 3 goals has about 25% (it's just a number, the real stat changes on every game), then if you find a middle of -3% for 0,5 goal, this middle has a great value. Of course there is important if the winning odd (in your example the under 3,5 side) has big odds

Personally my rules :

For soccer :
AH or OU : 0.25 point ->  -3,-4%

For basket :
AH : 0.5p ->  -0.5%
AH : 1p -> -1%
AH : more 1,5p -> more -3%
OU : 0.5 p - 1.5p -> positif middle
OU : more 2p -> -2%

For foot american : same basket

Currently ,that s work !

Some "expert" can give some idea about middles ?

no return about middles ?
I want  to know if i went in the good way.

example : go or not go ?

Hemofarm vs Crvena Zvezda OU: -159 1.909
Hemofarm vs Crvena Zvezda OU :+ 157 2.03
Return - 1.6%

result : 154

In fact, i need to know if my rules are too large or too tight !
Thanks

I think that is really hard to say. Personally I only play +0.0% middles. I don´t know how many middles you have played already, but with a good amount (~1000) you could make some good calculations. Just calculate how often a line was hit exactly, with 1 point difference, 2 points and so on. Then you could evaluate how long the middle is value.
