Pre-open phase (Opening Routine and Mid-day Break)

The Pre-open phase of the Opening Routine starts at 08:30am and ends randomly within a one-minute window between 08:58am – 08:59am.
The Pre-open phase of the Mid-day Break starts at 12:00pm and ends randomly within a one-minute window between 12:58pm – 12:59pm.
Investors can submit new orders and cancel or modify existing orders during the Pre-open phase, but there will not be order matching.
Orders queued in the order book prior to the start of the Mid-day Break will continue to rest in the order book.
SGX will publish the Indicative Equilibrium Price (IEP) to give investors an indication of the market level.

Pre-close phase (Closing Routine)

The Pre-close phase starts at 05:00pm and ends randomly within a one-minute window between 05:04pm – 05:05pm for full-day trading.
It starts at 12:00pm and ends randomly within a one-minute window between 12:04pm – 12:05pm for half-day trading.

Non-cancel Phase (Opening Routine, Mid-Day Break and Closing Routine)

The Non-cancel phase follows immediately after the pre-close phase ends.
Investors will no longer be able to enter, modify or cancel orders.
The trading system computes a price based on an algorithm, which is also used to calculate the IEP, set by SGX-ST. All orders that can be matched are matched at the computed price (“auction matching”).
Unmatched orders will be carried forward to the next trading phase.

Close

Market closes at 05:16pm (full-day trading) or 12:16pm (half-day trading).

Pre-opening Session

The pre-opening session is introduced to determine a fair opening price.

During the pre-opening session, orders are accumulated over a certain period of time and matched at the pre-defined order matching period. Orders are matched in order type, price and time priority (at-auction orders carry a higher matching priority) at the final Indicative Equilibrium Price (IEP).

The trading system only accepts at-auction orders and at-auction limit orders. The price of an order input into the trading system must not deviate nine times or more from the previous closing price or the nominal price (as the case may be), if available, or is one-ninth or less of that price. The maximum order size is 3,000 board lots per order.

Trading hours during the pre-opening session are as follows:

Order Input Period 9:00 am to 9:15 am	During the order input period, only at-auction orders and at-auction limit orders are accepted. Orders are accumulated and updated in the trading system continuously and may be modified or cancelled.	In the first period (a 15-minute Order Input Period), at-auction orders and at-auction limit orders within ±15% of the previous closing price can be entered for POS Securities. Orders can also be amended or cancelled during this period.
No cancellation Period 9:15 am to 9:20 am	During the No cancellation period, only at-auction orders and at-auction limit orders are accepted. Modification or cancellation of orders in the system will not be allowed.	Starting from the second period (a 5-minute No-cancellation Period), the allowable price limits are tightened, and the prices of new at-auction limit orders that aim to be executed in the POS must be between the highest bid & lowest ask recorded at the end of Order Input Period (i.e. recorded at 9:15am). In order to build an order book with deeper liquidity after the market opens, passive at-auction limit orders will still be accepted provided that these orders are within ±15% from the previous closing price. However, these passive orders will not be matched during the POS. Both at-auction orders and at-auction limit orders can be entered during the No-cancellation Period, but no orders can be amended or cancelled.
Random Matching Period 9:20 am to 9:22 am	During the Random Matching period, only at-auction orders and at-auction limit orders are accepted. Input, modification or cancellation of orders in the system will not be allowed. No order matching will be conducted if Indicative Equilibrium Price (IEP) cannot be determined.	In the third period (Random Matching Period which is up to two minutes in length), the order rules from the No-cancellation Period apply, and order matching takes place randomly within the two-minute period. The Random Matching Period will end immediately upon the start of order matching. At the end of the Random Matching Period, orders for all POS Securities are matched at the final Indicative Equilibrium Price (IEP). Order matching is based on order type (at-auction orders first and then at-auction limit orders), price and then time priority. In cases where the final IEP cannot be established during the POS, no order matching will occur.
Blocking Period 9:22 am to 9:30 am	During the blocking period, unfilled at auction limit orders will be carried forward to CTS as limit orders. Unfilled at-auction orders will be cancelled.	Once order matching is completed, the Blocking Period starts immediately and continues until 9:30am. Orders can no longer be entered, amended or cancelled during the Blocking Period.
