Jonny,
In all those trades, have you been able to keep a record of the average number of points gained in the winning ones? Strip out the very lucky ones, which can be construed as rare. You must calculate your stop losses-- and that includes the spread, commission, etc.---- to be less than those average gains, or you cannot make money or, at least, not worthwhile money. If you are averaging gains of 20-30 points, with only one trade a day then, I suggest that, stop losses of 14 points are too much. I have made 40 points at times, by trading the Footsie, but have rarely been good enough to do that in the first trade of the day, or even, one trade---although it does happen. Those who do trade all day, and I can't, may stand the chance of a better points gain, but part timers must keep their stops smaller, in my opinion.
