Precisely, something that is small for a glance, but if you want to see the specifics and such, you are able to with a command or something. I don't want all the info up from since well, it'll become spammy.
I like this idea also. I think a time period switch and transaction type switch on the command would help with the ability to determine when transactions occurred.
/transactions sell 24 (Show all the sell transactions for the last 24 hours)
/transactions buy 48 (Show all the buy transactions for the last 48 hours)
/transactions all 8 (Show all buy and sell transactions for the last 8 hours)
