Is it better to have a profit target for a certain time period, and to have a break from trading once the target has been reached, rather than risking going backwards from that point? I have a monthly profit target. The last two months I have achieved it quickly, only to lose some of my profits and fall short of my target in the end. I am not certain whether this is because I trade differently when my target is reached (psychological issue) or whether it was just due to the way my system interracted with the market over the period. A little of both I suspect. It would be nice to (when occasion offers) lock in profits part way through the month, then take a break. Yet at the same time, I am aware that this is not mathematically optimal - i.e. if your strategy has a positive expectation, then you should trade it as much as possible for maximum profits. Not to do so runs the risk of cutting your winnings short. On the other hand, one of the best traders I know had a career lasting only one year. He achieved his target (paying off his house) then just stopped. Why continue to risk if you are happy with what you have. Thoughts?
