老生常谈

交易中有很多老生常谈。比较有用的有：

* 市场永远是对的。The market is always right.
* 趋势在改变前，是你的朋友。The trend is your friend until it bends.
* 买回调跌，卖回调尖。Buy the dips and sell the tips.
* 低买高卖。Buy low and sell high.
* 支撑变阻力，阻力变支撑。Support becomes resistance and resistance becomessupport.

不要用你输不起的钱交易。Never trade with money you can’t afford to lose.
不要与市场耍聪明。Never try to be smarter than the market.
不要试图抄底与猜顶。Never fish the bottom or top of the market.
不要逆势交易。Never trade countertrend.
