Price from win market as SV in place market

[sheffutd1889]

Hi all,

I feel a bit daft having to post this as it seems like it should be quite straightforward but I can't get it working accurately. I want to see the price (LTP) of a selection from the win market in the place market. Initially I hoped it would be as simple as storing the price as a shared stored value for the selection from the win market and referencing that from the place market but no such luck. I figure values stored for the selection are limited to the market in which they are created

I used a work around to save a different stored value for each selection at the event level and then lookup the correct value for each selection in the place market. That SEEMED to be working but often I appear to get some wildly different values. Example attached, as is the rules file I've used if anyone wants to point out any glaring mistakes!

I then thought a smarter, and more accurate way would be to use the API to extract the price from the win market and pass it to the place market. I don't have a great understanding of how to use the API but I have successfully doctored a file @sniffer66 once posted for a couple of different tasks but can't get one working for this (again, file attached if anyone smarter than me can figure out why - had to put in a zip file as it wouldn't let me attach otherwise).

Any help would be gretly appreciated.

Many thanks

Re the Guardian method, is it because you're using Betfair order? This changes throughout the day as prices change, and of course there will be impact from withdrawal of non-runners.

Yes, I'm using betfair order but I fix the order in both markets as soon as the file runs (same file used on both markets so this is done simultaneously) so I don't believe price changes or non-runners should affect anything

I would use saddle cloths. See attached how I would do it. I've not tested anything.

Ah yes, that would be a more accurate approach, thank you. Still doesn't fully explain the inaccurate figures though, the figures it produced didn't belong to any selection (and there weren't enough non-runners for them to come from there either). I'll implement the changes you have suggested and monitor again throughout tomorrow. Thanks again
