Apr. 15 trades

I had 4 trades today - FCX, POT (both losers), SU, X were decent gainers. Today was a difficult trading day for me because I decided not to take partials today. Any price movement against the trade made me nervous and I wanted to take profits. I have noticed that since I take partials very fast, my R return on winning trades is very bad esp. because all my losers are 1R. I never set 2 SL for my losers. I have to work on my SL and trailing stops and will appreciate any feedback on how to improve them.
