cheers Rusty,
when i combine this with the bid/ offer, so you can see how large they are, it can often a giveaway. larger, round numbers, or combinations and parts there of to make big numbers can also be a sign, they want in and will push the price up to get it.
hope that makes sense? i think i just confused myself.lol
this is just how i look at things, i'm sure everyone has a different interpretation.
see you in Adelaide
happy
