Trading pullback in London session

Here is an example of how I traded a major move in London Open.
I do not like trading fast major moves like these, but try to get in on
the pullback instead - when I think the "bottom is in".
I am by no mean an experienced trader, but this is what I am watching
when trying to "catch a knife" like this...

Closed this one manually at brake even. Do not feel comfortable going into New York open without more Pull Back than this...
