Lumber Futures and Options Pre-Execution Contact Directory

What are Pre-Execution Communications?

Pre-execution communications are communications between market participants for the purpose of discerning interest in the execution of a transaction prior to the exposure of the order to the market.

Any communication that involves discussion of the size, side of market or price of an order, or a potentially forthcoming order constitutes a pre-execution communication.

Transactions that result from pre-execution communications must be entered into the competitive venue CME Globex following specific steps based on the product that they are executed in. For a list of the required steps:

Key Points

  • Allows market participants to execute trades when market liquidity is not evident
  • Find a counter-party to take the opposite side of a large trade
  • Pre-ex discussions can be used for executing both individual months as well as strips.
  • Interested parties are contacted to determine interest in taking the opposite side of a trade and given information on the price, volume, or direction.
  • If a counter-party is identified for a futures trade, the party that initiated the communication enters the futures trade into Globex. After 5 seconds, the counter-party can enter their side of the trade.
  • Pre-execution rules for options are different. Please reference the Market Regulation Advisory Notice for more details.
