I'll tell you quickly about something that happened to me that I found very inspiring with regards to running winners.
I used to work with a young guy called Lee. When I moved jobs I rarely spoke to him but he was on my MSN list so I would see him online from time to time and say hello.
I can't remember quite how it happened now but one day we were chatting about the trading I did in my spare time and he decided to open a spreadbetting account and "have a go" as he put it.
Now Lee was a complete beginner and having never done this before he, I suppose, looked to me for advice and I gave him a recommendation which was to buy Copper. This was during the bull market of 2006 and prices were rising steadily.
He told me he was going to buy 50p per point and see how it went.
In the meantime, I went in and out. Taking a small number of points here and a small number there. I was getting quite confident in my trading and would take long positions at several pounds per point, taking small chunks of the daily moves. The next day I would be buying in again at even higher prices and I would take a few more points and come out. I think, even at a few pounds per point I only managed to make several hundred pounds altogether but I was very happy with that back then as my account was fairly small.
When the moves upward in Copper became irrational with huge spikes upward in price, I went in again. Only I got in at the wrong time. I remember being long one morning when the market collapsed and losing not only everything I had ever made in the Copper market but also wiping out my whole account in the time it took me to get to work. It was some thousands and was one of my most painful experiences in trading to date.
Anyway, several weeks later I remembered Lee and and asked him how he fared in the Copper, hoping he had not suffered the same fate as me but presuming as he didn't have a clue what he was doing, that he had.
Well, Lee was very happy. He told me that when the prices had started moving up, day after day, more and more steadily he had added another 50p so he was £1 a tick net long. Then he just continued to check it from time to time, not worrying as prices were on the increase. After several weeks he started seeing the extremely sharp moves up, decided that although he might be leaving money on the table, it was getting a little irrational, closed his position for a profit of £800 and then closed his account too.
It was his only foray into the market. He never got shaken out when he saw price moving hugely in his favour and his gains increasing rapidly, he exited just when traders with many years experience like myself were getting enticed in through greed and he closed his account, realising the markets were wild and quitting while he was ahead.
Just something to think about.
