What is 10 points? 10 pips?, 10%?, 10 ticks (in futures)? If its 10 pips don't even bother: You'll pay 4-6 pips in commissions, besides your broker will manipulate quotes to make you loss the other 4-6 pips.
That would depend on either the stop (risk:reward) of the trade and/or the win:lose ratio of your strategy. There are some very profitable scalpers who target less than 10 pips but they also have a comparable stop, and/or their win:lose is good. If you're already in a trade and the market proves your analysis is no longer 'correct', and therefore there's no reason to stay in the trade, then even a 1 pip profit is better than a loss. Mainstream marketmakers rarely manipulate price or run stops just to get your money, it's a well-worn conspiracy theory
