I am not quite sure what you are asking?....did you make the transaction or not??....if you did not have enough buying power to cover the transaction then the purchase would not go through .... the transaction would expire......everything trade is listed up top ....under-- "Trade" .....then click on ...."My Order History" ......or go to ......"My Transactions"......
under these catagories you will find dates/times/transactions.....and whether or not they were filled or cancelled......
I hope this was helpful....
Happy Trading...!!!
