Speaking of out-of-whack market depths, i noticed a few days ago one of the shares i frequently check; NWR had bizaare market depth.
The Bid was .30 and there was an offer at .285
I kept refreshing and it stayed like that for a while, and then the next last price was something like .295
It was bizaare, i was very temped to buy at the .285 offer and sell at the .3 bid, but i assumed it was a bug and didnt try my hand at arbitrage. Was this just a comsec bug, or was there a reason why those bid/offers werent matched?
