An order is forced when it is submitted at a price outside the stated forced order bid spread. The system will alert you when you enter an order price that is more than the stated forced order bid spread from the current bid/ask prices in the market. You may wish to revise it if you have mistakenly done so.

There are a number of reasons your order could be rejected and the common ones are listed here:

1. The limit price of your order is more than the stated max bids away from the current bid/ask prices and the forced order option was not checked.
2. The trading limit for your account has been exceeded.
3. The stock you selected to purchase using CPF funds is not CPF-approved.
4. The stock you selected has been suspended.
5. The stock you selected has been delisted.
6. The SGX has encountered technical problems.
7. The system has encountered technical problems - such as outages, glitches and other delays.
8. The limit price of your order is not the same as the closing auction price during Trade At Close session.

If your order is rejected despite having checked and corrected any possible errors, please call our Customer Service Line at (65) 6327 2288.

Our online brokerage service automatically amalgamates trades when the trades are of the same stock, currency, settlement mode and trade date as well as the same mode of trade. For foreign currency settlement, if orders were placed at different times of the trade day, different foreign exchange rates may be applied for each trade. In this case, amalgamation will not be automatic. If you wish to amalgamate such orders, please call our Customer Service Line at (65) 6327 2288 by (Trade Date +1) for cash trades, and on the Trade Date for CPF trades.

A board lot is the minimum number of shares you need to buy or sell in a single trade (i.e., in a multiple of 10 or 100 units).

View the list of eligible stocks with adjusted board lot sizes here.

View the board lot sizes for individual securities on the Securities Prices page by selecting the "Board Lot" filter on SGX's Securities Prices page here.

It's not a once-off reduction. After the initial 5 Oct 2026 implementation for the initial batch of securities, the board lot sizes will be reviewed every calendar quarter to determine which securities qualify for a reduction in board lot size. The next implementation will be announced in January 2027 and implementation in February 2027.

Any changes will be announced within the first five trading days after the end of each quarter, with implementation within the first five trading days of the second month after the quarter.

No action is required on the investor's part. The change is only applicable when new trades (buy or sell) are made, when there is the option to trade in smaller sizes. No, a board lot change does not affect the number of shares you own.

No new stock codes will be created. The existing stock code will be retained and from the effective date will trade in multiples of the new board lot.

Board lot sizes will not revert. Once reduced, the board lot will remain unchanged, even if the price subsequently falls.

No different from existing process. Share transfer does not utilise board lots, rather shares are transferred in 1 share minimum.

The security's traded currency is used for the price threshold. For securities traded in SGD, S$10 is used as the price threshold. For securities traded in USD, US$10 is used as the price threshold.

Yes, investors remain fully entitled to the corporate actions declared by the company, regardless of the board lot size of their holdings.

Investors can continue to participate in corporate actions and receive entitlements through established processes:

• Participate in voluntary corporate actions through existing channels (e.g. SGX Investor Portal or by mail)
• Entitlements, including dividends, will be distributed through established processes such as the Direct Crediting Service (DCS) for SGD payments and the Currency Conversion Service for foreign currency payments

Consistency across currencies. For dual-currency counters, the primary traded currency determines the board lot size. The primary traded currency can be identified here.

Applies to new listings. New listings priced above the threshold will be assigned the reduced board lot from the first day of listing, unless otherwise informed.

SGX clearing and trading fees are a percentage of value traded, thus the fee would be the same rate at larger versus smaller traded values. Investors are advised to take into account total fees charged including exchange and brokerage fees which may vary based on the broker the investor trades through.
