TBILL:

Copilot eventually directed me to TreasuryDirect.gov.
Any of the below are potential sources.

I’d prefer an official document, but it might be a convention rather than a regulation.

Table of Treasury Securities — TreasuryDirect and When Auctions Happen (Schedules) — TreasuryDirect

General Auction Timing — TreasuryDirect

• 13-week and 26-week bills are offered each week. Except for holidays or special circumstances, the offering is announced on Thursday, the bills are auctioned the following Monday, and they are issued on the Thursday following the auction.

SFE to ASX:

If the conventions haven’t changed, then a change from SFE to ASX looks reasonable, at it appears to be the successor entity.
I’m expecting they haven’t changed, so shouldn’t require another different code, but let check with members to be sure.

When I asked Copilot, it gave an answer that contradicted it’s referenced source, but who know, maybe it indexed an older source.

Sent by you:

What was the convention for The last trading day of the Sydney Futures Exchange 90 Day Bank Accepted Bills Futures contract, and how does it differ from that of the ASX ?

Copilot:

The Sydney Futures Exchange (SFE) 90 Day Bank Accepted Bills Futures contract had its last trading day on the second business day before the third Wednesday of the contract month¹.

In contrast, the ASX 90 Day Bank Accepted Bills Futures contract has its last trading day on the business day immediately prior to the settlement day, which is the second Friday of the delivery month²³.

But its referenced source Futures Contracts – Last Trading Day says for SFE

which looks close enough to:

asx_90_day_bank_accepted_bills_futures_contract.pdf is more specific:

Last Trading Day: 8.29am on the business day immediately prior to settlement day.

Settlement Day: The second Friday of the delivery month

It may have conflated its answer with other lines in that document.
