Minimum Trade Requirements

US Markets

  • Fractional trading supported for most US-listed stocks and ETFs.
  • Minimum trade value: USD 1
  • Securities not eligible for fractional trading: Minimum of 1 whole share

Singapore Markets (SGX)

Fractional trading not available but odd lot trading is supported. See details below.

Minimum Trade Quantity:

Asset Type Minimum Trade Quantity
Stocks: D05, G07, H02, C07, J36, BN4, O39, K6S, S68, U11, V03 1 board lot (10 shares, e.g. 10, 20…) or odd lot (1 to 9 shares)
All other stocks & REITs 1 board lot (100 shares, e.g. 100, 200…) or odd lot (1 to 99 shares)
ETFs 1 share (whole shares only)

 

Bid Size and Forced Order Range:

Product Price range (S$) Minimum bid size (S$) Forced order range
Stocks, REITs Below 0.20 0.001 +/- 30 bids
0.20 – 0.995 0.005
1.00 and above 0.01
ETFs All 0.01 or 0.001 (as SGX-ST determines) +/- 10%
Example 1: ABC Group Holdings (stock), trading at S$40.00
Bid size: ABC trades above S$1.00, so its minimum bid size is S$0.01. Prices must move in 1-cent steps.
  • Valid limit prices: S$40.00, S$40.01, S$40.02
Forced order range (±30 bids): 30 bids × S$0.01 = S$0.30 either side of the reference price.
  • Accepted range: S$39.70 to S$40.30
  • A sell limit order at S$40.50 or a buy at S$39.50 falls outside this range and would not go through as entered.

Example 2: XYZ Index ETF, trading at S$4.00

Bid size: For ETFs, SGX sets the bid size per ETF as either S$0.01 or S$0.001.

  • If it's S$0.01: S$4.01 is valid, but S$4.005 is not valid
  • If it's S$0.001: S$4.005 is valid

Forced order range (±10%): 10% of S$4.00 is S$0.40.

  • Accepted range: S$3.60 to S$4.40
  • A sell order at S$4.50 falls outside the range and would not go through as entered.

Odd Lot Trading

Odd lot trading is only available for Singapore-listed securities and is not supported for US or Hong Kong-listed assets. It allows you to trade fewer shares than one board lot: 10 shares for the 11 stocks listed in the table above, and 100 shares for all other SGX-listed stocks and REITs. Charges and commissions are the same as standard lots. Odd lots are traded during the same market hours as standard lots.

To place an odd lot trade, search for the stock under Trade in the app and select “Odd lot” as your order type. Odd lots are not available in SGX Bundles, which trade in standard lots only.

Note: Only limit orders are allowed for odd lots. Market orders are not supported.

Most SGX-listed securities support odd lots, except ETFs, which already trade in single-share units.

Since odd lots typically have lower liquidity, to improve execution chances:

  • When buying, set a limit price slightly above the market.
  • When selling, set a limit price slightly below the market.

Key Points:

  • Minimum quantity: 1 share
  • Maximum quantity: 9 shares for stocks with a 10-share board lot, 99 shares for stocks and REITs with a 100-share board lot
