Get price liquidity

[Fralgo]

Hi,
sorry if the question I am going to ask is completely noob but I am just learning how to deal with the API-NG system and betfair at the same time for the first time.

Let's say I've got an horse racing, if I am not mistaking every depth has the price and relative liquidity(the amount of money currently available)
if I want to get the price and relative liquidity what am I supposed to do?

cheers

There's an awful lot to take in, so good luck with it all.

This is the online documentation:
http://docs.developer.betfair.com/do...lu3yomq5qye0ni

You can download the documentation in PDF form. This link opens up a version from December (which you should then be able to download), but I'm sure there's a later version that I can't find a link for. Perhaps a search on the forum might get you a better link.
http://docs.developer.betfair.com/do...cember2015.pdf

I would suggest that you create for yourself all the classes you might need from the information in the documentation. It will help you see how the data is structured and give you a solid idea of where to locate any piece of data you are going to require. A bit dull, certainly, but it would be wise not to expect instant or easy results in your project.

The data you will require for the odds and money available can be found with the listMarketBook call. Before requesting MarketBook data, you will have obtained the MarketCatalogue data for the market. The MarketBook data, here
http://docs.developer.betfair.c
om/docs/display/1smk3cen4v3lu3yomq5qye0ni/Betting+Type+Definitions#BettingTypeDefinitions-MarketBook

includes data for each runner in an array/collection/whatever, here
http://docs.developer.betfair.com/do...nitions-Runner

and most of what you require will be listed under exchangeprices, here
http://docs.developer.betfair.com/do...ExchangePrices

and

http://docs.developer.betfair.com/do...ions-PriceSize

The price is the odds and the size is the stake.
