Are energy futures delayed on C2?

I’m a system developer. I tried trading Nimex light crude futures, but the trade(buy at market price) was executed only the next day in Collective2, and the collective2 price was strange(5 dollars lower than the actual price for that contract, this price was in the marked like one week ago).

Does collective2 delay the trades on energy futures? Is the price also delayed? Do they not favor energy futures?

What symbol did you use? Make sure you are using the electronic symbol and also the correct expiration month. The electronic symbol is QCL while the pit symbol is CL. There’s almost no volume in the pit contract.
