Need Help. Dont understand what happened here

[westoncott]

Anyone who could throw some light on this I'd appreciate it.

My automation file simply puts a back back (£2) in the place market on the favourite just before the off.

Then it does nothing unelss I'm losing >60p when it "reds" me out.

In this race it placed the bet - the horse went on to win, but in the dying seconds it Layed the horse causing me a loss of £13 !

Here is the info from Sporting Life as to how the race went, and the Log from Bet Angel, and the bet info from Betfair.

I cant understand why it Layed at 15 when the horse was almost home.

Any ideas. Can I see anywhere how the odds moved during the race retrospectively?

for a start your saying if the loss is greater than 60p that is your mistake

[ShaunWhite]

Firsty you seem to be backing £1 rather than 2 but that's an aside.

The £1 lay looks like a closing bet rather than a greening transaction (the stake equals the liability, not an amount calculated to green up)

Inplay prices fluctuate rapidly and are very gappy. It's perfectly possible that the first occasion your loss exceeded 60p the best available price was 15. The sporting life description just says 'stayed on top' but doesn't give any indication of how much it was challenged or looked tired. If it looked like it might be beaten at any point, backers would have withdrawn their money and the lay price could easily have spiked.

The loss is > 60p. The profit is <-60p.

We both get it, it's just semantics.

[westoncott]

OK Thanks guys.

Yes I meant a loss of more than 60p. It's worked in loads of other situations, and I expected the answer to be gappy odds etc, it was just that it was right towards the end of the race and the odds usually stabilise a bit there.

Thanks for your input.

Mike.
