また、その下の例の解釈が、(either trade)がどこに掛るのかが良くわからず困ってます・・・。 →either A or Bの形しか知らないので、なんでこんなにeitherが出てくるのか・・・。
どなたかお分かりになる方がいらっしゃいましたら、よろしくお願いします。
Stabilization. Specialists are prohibited from making de-stabilizing trades in their specialty stock. **A trade is de-stabilizing if the specialist:
A) buys at a price above the last different price; B) sells at a price below the last different price.
Example: DTL trades in the following sequence of prices:$7,8,8,9,11,10,12,12,14,13,13. The DTL specialist would be guilty of a de-stabilizing trade if he bought at $8(either trade),9,11,12(either trade),or 14, or if he sold at $10 or $13(either trade).
**This rule prevents specialists from contributing to price swings in their specialty stock. In the real world, there are exceptional circumstances under which specialists may make destabilizing trades in their specialty stock, but the spirit of the real rule is captured by the game rule.
まずこの部分ですが、
>:$7,8,8,9,11,10,12,12,14,13,13. The DTL specialist would be guilty of a de-stabilizing trade if he bought at $8(either trade),9,11,12(either trade),or 14, or if he sold at $10 or $13(either trade).
これは、株価が$7,8,8,9,11,10,12,12,14,13,13・・・と、変動していた場合の例です。
either tradeについては、8と12と13が2回ずつ出てきますので、そのいずれの場合もだめですよという意味です。
