i gave up first time as well.
But its actually quite simple to back and to lay.
With back you basically say how much of a premium you want OVER the supertab price and with lay you advise how much of a premium you will pay OVER the supertab price.

both prices limited to max 30 win and 11 place

however i agree there are some improvements that i could see also.

you should see the liquidity on the Asian races like HK and SING.
huge.

and more importantly from what i have observed you can get easily supertab +10% and you wont be banned.

sometimes +15%

Well I gave up for now too but will revisit it later.
I'm sure they make it sound more complicated than it really is.

Am I right that the max lay price is $30 and $10 respectively?

That's how far I got.

yes that's right.

Is that clear, Danny?
Crystal clear, Colonel.

"You want the truth?" snaps Colonel Jessup. "You can't handle the truth!"

Is the back price regulated too?

I love the last 30 mins of that movie, RP.

Denzil Washington is the man IMHO, never made a bad movie.

As for ABE, I've emailed them to verify their creds.

Not too many have shared their best filters Maark, have they? If you're still around my best advice is to look where no-one else is looking. New punters come along all the time and currently we have sophisticated ratings to help pick the winners (the fav S/R hasn't changed in 100's of years tho'), years ago these same ratings were to be found in the Sporting Globe tipsters columns, they went under a different format. Today's is more exciting, but no more profitable. So we still keep looking at the usual good form, newbies come along and join in and they look for good form, a tweak here and a tweak there and they've nearly got it!! But they haven't and never will, çoz the odds will get you all the time when you're looking for winners using similar methods that everyone else does.

Look where no one else is looking and test (don't backfit).

good luck.

and to add to what Barny says then if you do luck out and start to get some winners the bookmakers wont bet with you.
