The rules are working and automatically placing bets if the rule conditions are met (I turned off confirmation), but I don't see any evidence of any past bets having been made. But I know they were, I see in the BetAngel "underlapping" window, my balance is changed from my original deposit amount.
For some bizarre reason though the "Matched bets" column only ever shows a Matched bet while it's still in play. As soon as the race is over, that Matched bet gets reset to zero as you can see in this screenshot below. On the current race, I have one matched bet (that's £1 of the £4 that my initial £100 deposit is reduced by to £96). The other £3 of that £4 reduction was from 3 earlier £1 bets above, but they're not shown. So I have no idea which of those races I bet on unless I login to the betfair website and look.
Can I stop Guardian from forgetting about the past bets it made? It'd be nice if it even showed if they were a winner/loser. Maybe a column "Win/Lose" would be enough. Or am I a weird user to want to leave Guardian taking care of my bets and expecting to come back at the end of the day to "see how I did"? Are others staring at the screen the whole time and leaving bet confirmation turned on? That's not really all that automated.
