RollupModel

[joeyjoeuk]

Hi, could anyone explain what the RollupModel is, what its for and how its might be used please? I don't remember coming across it in API 6 and the explanation on the API-NG documentation is limited.

I'm thinking in the context of how it would impact the AvailableToBack and AvailableToLay responses in a listMarketBook request.

Thanks!

Rollup model is just a helper that allows you to aggreagate bets with the same price. It helps to avoid some calcs, but to be honest this feature is not of great value

Thanks AlgoTrader

Besides aggregating bets, the roll up model can also be used to filter the prices on minimum stake or payout.

So if you set your rolluplimit on 10 and your rollupmodel on 'Stake', all prices with stake below 10 are not returned.

Does the rollup model work when getting prices? Did someone check it? I tried it (using exBestOffersOverrides.rollupModel and exBestOffersOverrides.rollupLimit parameters) but results were without rollup.
May be I made some error.
Thank you.

BTW, exBestOffersOverrides.bestPricesDepth parameter also doesn't have any impact on the returning results.

it works for me, including BestPricesDepth.

it works for me, including BestPricesDepth.

Could you please write the example of your request? Just to see what other params do you use.
Thank you.

Here is my request:

{"priceProjection":{"priceData":["EX_BEST_OFFERS"],"exBestOfferOverRides":{"rollupModel":"STAKE","rollupLimit":50},"virtualise":true,"rolloverStakes":false},"marketIds":["1.111178786"]}

No rollup is made using it.

=========
Found the problem (mistyping): exBestOfferOverRides should be exBestOfferOverrides.
I am sure that I've copied it from Wiki page, but may be I'm wrong.

Great, btw I use the API-NG Visualiser and Javascript console a lot to check the responses and requests of all API calls and their different parameters.
