老生常談

交易中有很多老生常談。比較有用的有：

* 市場永遠是對的。The market is always right.
* 趨勢在改變前，是你的朋友。The trend is your friend until it bends.
* 買回調跌，賣回調尖。Buy the dips and sell the tips.
* 低買高賣。Buy low and sell high.
* 支撐變阻力，阻力變支撐。Support becomes resistance and resistance becomessupport.

不要用你輸不起的錢交易。Never trade with money you can’t afford to lose.
不要與市場耍聰明。Never try to be smarter than the market.
不要試圖抄底與猜頂。Never fish the bottom or top of the market.
不要逆勢交易。Never trade countertrend.
