Limit orders

An order with a Limit price means:

  • For buys, the highest price you’re willing to pay for a share
  • For sells, the lowest price you’re willing to sell a share

It’s used if you want certainty about the price you could ultimately get.

Keep in mind

Your order may not trade immediately because:

  • it’s outside of market hours;
  • there may be other orders ahead of you at the same or better price than yours. The market processes orders based on “price-time priority” (those at a better price first; and, if at the same price, then by the time it was submitted);
  • there is no demand at your price at that point in time; or
  • we may have to perform additional checks on your order before we send it to market.

We also may reject Limit orders that are too far away from market prices.

“At Market” orders

An order that’s “At Market” means:

  • For buys, you’re willing to buy at the available prices offered in the market
  • For sells, you’re willing to sell at the available prices bid in the market

This type of order has no limit on the price you ultimately get. It’s used when you want to execute quickly and you’re happy to accept the going prices on the market.

Timing and price can vary

“At Market” orders are sent to market as soon as practicable in accordance with our Best Execution Policy and T&Cs. But it’s important to note that market conditions can affect the timing of your order and the price you get, for example:

  • The price you receive may be significantly different to the market price that you observed when you placed the order. This happens particularly in volatile markets when both supply and demand for shares and market prices can all change quickly.
  • Your order may take time to fully trade - longer than you anticipated. This happens particularly in illiquid stocks, when supply and demand at tradable prices can sometimes be scarce.
  • Your order may need to be checked before submission to market. It’s CommSec’s obligation as a market participant to do our part to ensure a fair and orderly market. Therefore, your order may need to be checked when it could fall outside our guidelines.

Keep in mind

  • “At Market” orders are only accepted during market hours, generally 10am-4pm Sydney time.
  • “At Market” orders cannot be amended or cancelled online once they are placed, and rarely over the phone, because they’re generally fulfilled quickly.
