仮想通貨の取引所での注意文なんですが、辞書ひいてもよくわかりません。
翻訳お願いいたします。

Fill-or-kill in Spot Token Trading: Should an order would be filled,
regardless its filled quantity, at the price of ±20% from best bid & offer by the time it executed in the orderbook,
the said order would be entirely cancelled.

Otherwise, the order would be executed and matched normally.
