no redgkey, that how the auction is.
for example price they will get will be 7.4c. One of the bids side bid 8c so make sure that their bid will get at market price around 7.4c. Similar for the other side, they try to sell it at the market price so they put in much lower sell price so they make sure they can offload their shares.
Normally, Traders try to buy and then sell a stock within 2 days to avoid settlement.
