The figures are comparable all days, except for the races where there are really small field sizes on the whole card.

Did you get a similar result to myself?

Used method 2 only +5.53 units
Had I used method 1 same result 19 units profit. (Hindsite)

Ah o.k.
Sometimes one method beats the other, but they are each independently still kicking goals.

Still haven't used this on the local races but did achieve some success with a variation for the UK races last night. I'm restricted to Saturday and public holiday Australian meetings at present :(

Hi Chrome,

If everyone using your method used the IAS market and the same criteria for back or lay, then we would all be backing or laying the same horses. Wouldn't this mean that, on average, we would be backing at a lower price and laying at a higher price?

You mentioned that the liquidity would be better, but it would only be one side of the market.

Angry Pixie,

I haven't looked at using this with the UK markets as yet, but after it all settles down, I plan to investigate and analyse this further. The main problem I can see is that most of the markets just list the current market price and not the fluctuations.

True, but not necessarily.
If 20 people are looking to back a horse in the final minutes and have a set price criteria, then the price should go up by demand. Layers would have to increase the prices offered in order to get matched. As long as the backer doesn't take whatever is available regardless of price.
So optimally, if layers aren't getting matched and want to, they must raise their liability a few cents.
Of course you could argue that if the backer wants to get matched, he might have to do the same, but looking at the trends, if enough demand is there, you'll get matched, the more demand (read money), the more likely to get matched (within reason).
I've almost always managed to get a few cents higher than the amounts traded in the final minutes.I take one bet at the current available and two bets at 10% above that.

Gave back a bit today - a loss of 11.14 units

May Tally

128 wagers
20.14 units profit (less the 5% commission)
15.73% POT

Ladbrokes seemed to work for me last night. No auto refresh though. Just applied your rules but only worked the lay side.

Just had a gander at Ladbrokes.

Yes, it should work fine under "view as racecard" as this view shows the fluctuations.

I'll start to keep records in June, as May I have set aside to finalise the analysis for Aussie races.
