It should be 110.21 NOT 111.56. I tried to post a jpg of the error but not allowed. Instead of worrying about not allowing stock sales, you should make sure your data is correct. I have been using Yahoo finance since 1997 and the new version totally sucks. It is slow as **** to load and many times the stock prices are incorrect and I have to keep refreshing to get the correct prices to load. FIX IT.
