I am very new to access so please bear with me. I would like to use access to do similar task on stock trade data. The spreadsheets I would import into access would have the following data: Client, Trade Date, Stock Symbol, Buy/Sell, Shares, Price and Total Cost. I am interesting in returning, for example, a list of all trades where the same stock was purchased or sold by 2 or more clients on the same day but at different prices. Can anyone help me with this. I have used logic parameters and calculations in excel but I dont have the hang of queries in access.

Thanks alot in advance
