...after stripping the "1:" of one of the bet IDs. What's the flipping point of the 1:? :lol:

I've given up the idea of automating my accounts, the data is so inconsistent. Racing has the event location where other sports have the sport name, and the distance/type for the race where other sports have the market name. Thanks a flipping lot Betfair. :x :x

Just drop @BetfairCS a note, I'm sure they would sort all these problems in a jiffy! ;)

You can cross reference BF P&L with BF Betting Activity / Betting History / Settled
Thanks, but that just shows individual transactions, not market profits or commission.
You can then aggregate the Settled data by race to match that P&L

Betfair calculate commission differently if you are on PC, so it's a murky area.

They use implied commission. So even if you pay commission at a base rate of 10% on an Aussie market, they will re-calculate it so it's only like you paid commission at 3%.

I trade several sports and they concatenate event and selection into one field with just a space separating them. Given that some football teams names consist of two words it feels a bit error-prone. On top of that, it doesn't have all the data I need and what data it has is quite mindlessly split over two files, so I think for now I'll continue to do it manually. It would be so easy for Betfair to just chuck a comma in the file: start/settled date, event, market type, selection, etc.

Isn't it easier to reconcile the various files on marketId and selectionId?

I could do that, but I like to query my data on meetings, leagues, competitions, etc. So I'd still need to enter markets manually.

I was aware they used a 3% assumption for all losing markets (an implied comm therefore of 1.5% on all losses).

I thought implied comm on winning markets was always half of actual commission paid? eg 1% on most markets but significantly more on aussie markets. Is this not correct?
