Sigh, yes, it is confusing.. I myself even tried to play some games with a few of these, like when I am high bidder I like to downtick my bid one blip at a time, because I know that it makes trading platforms show red :)
I am learning!! Slowly.
PS: It has worked a couple of times, upticking the ask shows green on trading platforms- too ... I did that a lot on PUN*
