i recently trialled APN. I found it to be way behind actual flucs time wise. By the time the bookies changed and the data got through it was 5min late. I use Betchoice & Sportingbet sites (and of course Betfair for general movemment)for on time flucs from the ring. Prob only need 1 though as they change within seconds of each other and are very close.

Any reason why you want TAB prices? The first thing i ever learnt was following TAB prices is a furfy. Ive seen TAB prices $2.90 for a horse geting thumped in the ring. By the time the TAB catches up the actions over and they've jumped. Worse the other way when they have one at $1.80 but its really $2.80 and blowing in the ring. Other theory is smart punters dont use TABS so why follow dumb money.

TAB monitering compared to Bookies flucs = Different planets. You used to be able to see / tell if bookies are offloading the risk onto TAB to follow a good thing but these days Betfair trades higher then TABS and bookies can chase the betfair overs so its not as obvious if your just a TAB watcher.
