Traded Amounts not returned by API

[loudsight]

Hi
I'm trying to get traded amounts per runner at each price level via the API
Ex. £2345 @ 1.68 for Peter Heller (see betfair website screenshot attached)

I'm using the Java code below, but an empty array is returned for traded amounts:


ListMarketBookParam param = new ListMarketBookParam();
param.setMatchProjection(MatchProjection.NO_ROLLUP );
param.setOrderProjection(OrderProjection.ALL);
PriceProjection priceProjection = new PriceProjection();
param.setPriceProjection(priceProjection);
priceProjection.setPriceData(new HashSet<>());
priceProjection.getPriceData().add(PriceData.EX_BE ST_OFFERS);
priceProjection.getPriceData().add(PriceData.EX_TR ADED);
priceProjection.setExBestOffersOverrides(new ExBestOffersOverrides());
priceProjection.getExBestOffersOverrides().setBest PricesDepth(5);
res = betfairOperationsAPI.listMarketBook(param);

I see the same behavior when using the "NG API Demonstration Tool" - https://docs.developer.betfair.com/visualisers/api-ng-sports-operations/

Live & Delayed Application Keys Usage

The createDeveloperAppKeys service will assign two Application Keys (App Keys) to your Betfair account.

One 'Live' Application Key and one 'Delayed' Application Key. A Delayed Application Key is displayed as 'Version 1.0-DELAY' via createDeveloperAppKeys/getDeveloperAppKeys

Key points:

• Upon creation, the Live Application Key will be inactive.
• The Delayed App Key operates on the live (production) Betfair Exchange and not a testbed/sandbox environment.
• The Delayed App Key should be use for development purposes and any functional testing. The key provides delayed Betfair price data. The delay is variable between 1-180 second snapshots.
• The Delayed App Key must also be used in simulation/practice applications where the facility to bet into live Betfair markets is not available.
• The Delayed App Key does not return traded volume data 'totalMatched' or EX_ALL_OFFERS via listMarketBook.

Thanks - I missed that in the docs.
