Late money, good money?
 

Just wondering if anybody can provide proof about late money. I have been looking at trading on BF by backing horses then laying them off...
The obvious draw back is that if you back a horse and the price doesn't come in, then you are left with a bet on that horse... And if you back a horse and the price comes in then you can lay it off, but because the money is for it it may have a better chance of winning?

Does anybody have access to any stats of this description? eg.. An easing favourite with a start price of $3 compared with a firming favourite with a start price of $3.
Obviously I am after all prices, not just the $3.
