Gain and Loss of a sold stock

Dear Portseido,

This is Vincent Mak from Hong Kong, I am happy to tell you that i feel good in using your serice and i am planning to subscribe it. However there is one question I wanna ask. I had done ten transactions of stock 0700.hk. and eventually i sold all of them. I cannot find the stock in overview anymore, so where can i find the gain and loss of this stock ? Please advice.
