Stand in that hall and look around, and you can see all three uses at once — the building you are standing in, the body that set the rules for who may trade there, and the noisy business of trading itself. The hall is mostly empty now; the trading moved into computers. But the word kept all three, and which one a sentence means usually shows up in the small word in front of it.

可以想成這樣一個場面：一個大廳，人們帶著錢進來，換走公司的一小塊。站在那個大廳裡往四周看，這個字的三種用法會同時出現——你腳下站著的那棟建築、訂規矩決定誰可以在這裡交易的那個機構，還有滿場喊價、買進賣出的那門生意本身。現在大廳多半空了，交易搬進了電腦裡。可是這個字把三樣都留了下來。要分辨是哪一個，看它前面那個小小的介係詞通常就夠了。Two branches
