That is about the size of it and, unless your SL is guaranteed, you are still exposed to significant jumps or overnight news. Many will disagree but the stop loss is no friend of mine, they only ever caught me out because as soon as my trade was automatically unwound, the price came back towards my target.
If you want, you could set the SL at 850p in this case as that may mean that your broker will require less margin than with no SL. You then follow it fairly closely and close the short manually if things go against you. Of course, it is more tempting to take a profit than a loss. I can tolerate big red numbers on my screen but when they turn significantly positive, I am itching to close.
