Trading Members and Trading Representatives would generally be familiar with the patterns of trading in each security or futures contract. They are therefore expected to exercise judgment, based on their experience and knowledge of trading in the security or futures contract, in assessing the likely impact of a proposed transaction on the market for a security or futures contract. This is especially so if the execution of the transaction would result in a significant change in the price (which is inconsistent with the recent trading activity in the security or futures contract, including the intra-day, daily, weekly or monthly price range) and represent a significant proportion of the daily traded volume in the security or futures contract.
