Auction Mechanisms

The opening and closing market phases of the Singapore Stock Exchange are described in detail in Practice Note 8.2.1, which can be found under the SGX-ST Rules page.

Open

Orders can be entered from 08:30:00 to 08:59:00 (pre-open), followed by a non-cancellation period from 08:59:00 to 09:00:00, after which order matching will occur and the market will open.

Close

Orders that can be matched are matched at a single price computed based on an algorithm set by SGX-ST. The computed price will be the closing price for the day.

Note: in PPro8, the Flattening button does not work in the closing auction for this market. Instead, orders can be flattened only by manually sending a limit order that is not too aggressive, i.e., set close to the market price.

The methodology for computing the single price is as follows:

The methodology for computing the single price at which orders at the end of the Opening Routine, Closing Routine, and Adjust Phase are matched (“Equilibrium Price”) is as follows:

The Closing Range shall be the last 15 minutes of the Trading Phase, or such other time as may be determined by SGX-ST and notified to the market from time to time.

Unless otherwise specified, SGX-ST may use any of the following as the closing price of a Prescribed Security for a Trading Day:

Where SGX-ST deems it necessary or desirable for ensuring a fair, orderly, and transparent market or the integrity of the market, or for proper management of systemic risk in the market, SGX-ST may use an alternative formula and/or procedure to determine the closing price of a Prescribed Security.

Auction Periods

1. Pre-Close Phase (17:00 - 17:04-05)

All unmatched orders can be entered, reduced in quantity, or cancelled. No matching will take place.

2. Order Matching (17:04-05 - 17:06)

No order entry, amendment, or cancellation is allowed in this phase. All existing orders are matched at a single price according to the algorithm set by SGX-ST. All unmatched orders following the non-cancel phase at the close of trading will lapse. The computed single price will be the closing price of the day.

Auction Order Types: Limit order with TIF set as DAY.
