For the purpose of this discussion I'd like to focus on one of the free pro data files: 28/03/2022 event id's 31330696, race id's 1.196743870
To make things a bit simpler i've created a new file, attached, that is just the 'rc' entries for horse id 12666330
First question I have is: if we just take the various 'atb' entries, is it a good/reasonable plan to just add new price entries to an array/dictionary overwriting values if already present and deleting any with value 0? So, at any one point you'd have a list of all the prices and volumes available to back? In the example file attached by row 6 the only price available for this horse is 1.01 with a volume of 2257.46. I.e the volume for 1.01 have been overwritten and not accumulated.
There are a few other questions I have about when the various other properties show up such as 'trd', 'spn' etc but they can wait, as it might be best to ask one question at a time. Obviously a useful resources here is https://historicdata.betfair.com/Bet...cification.pdf but I'm not sure it's quite enough to just read and know fully how to handle a 'pro' file in a useful way.
