The ICE fines trader for "disruptive trading" in the pre-open - a term that is broader than "spoofing"
While there have been multiple disciplinary notices from the CME regarding entering orders without intent in the pre-open, a disciplinary notice from ICE US Futures is the first from that entity that DCM has noted regarding per-open orders entered without intent to trade but rather for market intelligence.
The ICE notice references two factors: "the intent to determine market depth and the effect these orders would have on the Indicative Opening Price (“IOP”)." This has been a common theme for these types of disciplinary actions - using orders as an information gathering tool, not for execution. It should be noted that the recent CME and ICE notices reference "disrptuive trading" which is the name of the general rule that covers entering orders without intent to execute, even if they are not intended to move the market to enable a trade in the opposite direction. Companies should be using this term regardless of whether they also use "spoofing" as a term in their training.
It feels like a broken record repeating this but I have had multiple conversations with different regulators and they all have a common view of US futures markets - that these are markets for execution, not negotiation. If you wish to utilize the futures markets for anything other than execution, your actions are improper. to the regulators, just the act of entering these orders causes other participants to misunderstand the liquidity of the market and, therefore, that order is disruptive.
You are allowed to change your mind based on information received after the order is placed but you to have intent to execute when the order is entered.
The fine was $50K and a ten day suspension from accessing the market. notice is case no. 2017-023 from ICE US Futures issued August 14, 2019. I do not have a link to the notice at this time.
