RT, information overload is the major issue for a day trader, you need to find ways to cope with it or even better to use it to your benefit.Yeah, it is quite high compared to what RH advises, but i have belief in the system that it will make a steady profit over the long term. Drawdowns do hurt a lot more but i try to look at the cumulative pip column rather than my cash column.
Whether 5% is too high or not - nobody else can answer it better than yourself. It has two aspects. One, how you manage it psychologically. You seem to be unaffected, well done. Two, you should know now what will happen if your capital is gone. What's you plan? Will you quit? Start paper trading? Put some more money into a different system? Only you know.
