Agree with LG, RCP's post is essentially what i'm aiming to do, find a profitable angle that others:

1) do not know about
2) cannot access
3) decide to ignore

In reference to your post LG i think price is initially based on form but the way its manipulated through until close can sometimes move away somewhat from form. Now please note this is just my observed opinion and I don't utilize this myself currently but:

Let's say you have a favourite in a field at $4 in race 6 on the card. It flucs a little throughout the day but not much however now it flashes up as the next race on all TAB's and TV screens around the country. You'll have some people getting on it just because its a 100 rater, some betting anything BUT the favourite. Then comes tha announcement that the favourite is the market mover and you might get a splash of more money driving the price down. Some of these things are form related and some aren't, which I suppose is the nature of the game.

But the way I think and i'd be interested to see if there is any evidence people have to dismiss or back this up, is that if a favourite is at say $4 and then the commentators, tipsters, ratings and whatever else support it and in the leadup to the close it gets 'crunched' into $3, haven't you now missed out on the value that was available on that horse and it therefore becomes a lay? I'm not sure how often this scenario happens or if it does at all but its almost the thinking of a trader where you want to back something at its top fluc and lay it at its lowest available price. So if you've missed the boat on something that gets crunched, sure the public and whoever else has got on board may think it has a great chance of winning, but because you've missed those higher juicy odds doesn't it now constitute either a no bet or lay bet? Interested in peoples thoughts.
