I ordered it and tried to use with IB TWS. I will probably have to download the newest build of TWS because it does not work with my current build (May 02). You will not get a refund because the software is guaranteed to work, or something to this effect.... Perhaps it does work, perhaps it does not. It's just a simple spreadsheet with links. $50 seems a little bit too much for something like that, particularly that this is not that sophisticated as many other programs that you get for this price. And the whole thing is not as hassle-free as you would expect. At least, it was not in my case.
