即買賣差價窄且單子數量大，流動性不好的例子就不說了，很多。 第二，bid ask spread/ 買賣差價大小。 買賣的差價非常非常非常非常重要！！！ 差價大小嚴重影響你的盈虧比。舉個栗子， delta 0.3 的一個call， 理論上是 underlying漲1塊錢，這個call 漲 0.3， 爲了方便起見gamma 忽略不計。如果股票價格是100, 你覺得一週內內股價會漲到102，差價小的情況是delta 0.3 的call的價格 是0.2@0.22 （市場買價是0.2，賣價是0.22），你以0.22買了這個call，當股價是102的時候， 這個call的市場價是0.6@0.63，假設你以0.6的價格賣掉，那麼你淨賺0.6-0.22= 0.38. 那麼差價大的情況是 delta 0.3 的call的價格是0.1@0.3，假設你以0.3買了一個期權，當股價是102的時候，這個call的市場價是0.4@0.8，假設你是個小白，你以0.4的價格賣掉了，那麼你的淨利潤是0.4-0.3=0.1 縱使你英明的押對了時間和方向，你的風險和回報是非常不成正比的！不管你是投機方向還是波動率。","text":"看了那麼多理論之後，相信很多人在摩拳擦掌躍躍欲試了，再忍忍，白給市場送錢不如送給我，哈哈。 下面幾點是一定要在交易之前先考慮到的，要不然學費交了還什麼沒學到。 第一，市場有沒有流動性。這點其實是不管你交易什麼品種都要考慮到。 少交易毛票因爲沒有流動性。外匯交易受寵因爲流動性好。流動性的好壞不光影響到你建倉的價位，也影響到止損/止盈的可能性和價位。 何爲流動性呢？簡單的說，就是你的買賣不會大幅度影響市場價格。比如有的股票可能買1萬股，可能就會把股價推高1%，有的股票買10萬股，股價都不動。期權也一樣，比如S&P500 ETF SPY 的流動性就很好， bid/ask spread
