Is anybody using excel to place orders manually? For example, click on a button in excel to transmit/cancel an order? Similar to IB's TWS but all within excel? Thanks!
TWS has an Excel API demo spreadsheet with order submission samples. I have not used Excel for trading since 1998. Any reason why you would prefer it?
There is a good thread on "Excel Automation" under the Automation section of the forums - just search it.
