The truth is there is NO best time or accurate time to take out your investment once you hit profit. If you're the type who always gets their hunches right, then you should stick to what you feel. If your mind tells you that the your trade will still gain more profits, then you keep holding your investment. If you're uncertain about it, then you should probably take out your investment. The key is to avoid losing what you invested so like I said, if your hunches are always right, then follow it.
