Bit stuck... I was wondering if there was a way to do a relative odds comparison between the current selection's ActualSP and its ProjectedSP. Presently, we are able to compare the current selection's various attributes to any other selections' attributes as per the shot below:
However, this appears to only allow us to compare the current selection against OTHER selections (rather than explicitly comparing *The selections - Actual Sp* --> *The selection's Projected SP*).
am i missing something here, or would this allow for a direct tie in comparing these two attributes on the SAME selection in a one-to-one fashion??
[edit] - i have made an assumption that the ProjectedSP is a dynamically changing value that is recalculated as the market evolves. if this assumption is incorrect, then there is no need to address this question with an answer. the prime reason for the comparison is that i wish to know if the odds are EXPECTED to change in one direction or another on a second by second basis, in play, and thus wish to review those in comparison to the opening sp.
ProjectedSP - ActualSP comparison
Where you currently have 'of ANY selection' just replicate the way you are choosing the selection for the rule (on the General page). i.e. If you are choosing the rule's selection 'by name' then also choose 'by name' in the Automation Condition. Or if it is 'by position in order of favouritism' then do the same in the automation condition. In that way, you know the selection it is choosing for the Projected SP will be the same selection that it is using for Actual SP.
Alas, it is a *loose cannon* rule where the selection is flagged via signals at the off and is not tracked via betfair row or order of favouritism etc. I know what you are suggesting but unfortunately, there is no hard coded handle on this particular selection (it may have started off as fave and is now pos #3, but my signal has picked up that i can now do something with it, IF the projectedsp < actualsp etc).Bet Angel wrote:Where you currently have 'of ANY selection' just replicate the way you are choosing the selection for the rule (on the General page). i.e. If you are choosing the rule's selection 'by name' then also choose 'by name' in the Automation Condition.

hope this makes sense...
Ahh -ok. I have misunderstood this attribute then. I had thought that you were looking across the book and assessing the relative book% decay and then pro-rating a new value to the projectedsp odds, based on the new book% -Bet Angel wrote:Projected SP is betfair's estimated SP value, at this given moment, based on the amount of money on each side of the touch price of the selection and the number of bets on the exchange that are currently marked as taking SP.
i.e. if previous odds were 3.5 on a book% of 15, the new projected odds would be 3.5 odds factored by the new book% (which could now be 13.5%).
hope this scans
ok... looking at it another way. would it be possible to add a new attribute to the Historic Relative Odds condition (or probably more correctly extend the Book Percentage Condition). See below:
this actually covers off more or less what I'm trying to accomplish, as it's more the market share that i'm interested in, than the odds price themselves!!

this is purely for horse racing as the market neatly boxes itself into a closed system, which tallies to anywhere between 100 and 125% (but we can approximate this to 100% for our purposes). by being able to understand the relative market share of the runner, we can then make a better educated guess as to where it's heading, rather than on purely comparative odds per se (i.e. we can use it as another dynamic metric to get underneath the odds, especially if the odds have not comparatively changed that much on the top 2-3 runners).jkirley wrote:what context are you trying to use this for? which sport for example
