It’s possible to trade after the market closes — if your platform supports it. But before you engage in after-hours trading, weigh the benefits against the risks.
What is after-hours trading?
After-hours trading means placing a trade after the market closes, which you can do long as your broker allows it. Market hours differ based on the stock exchange. Not all trading platforms offer pre- and post-market trading, and those that do limit extended trading to set time windows that vary by broker.

How does after-hours trading work?
Extended trading hours vary by platform and trades are facilitated by electronic communication networks (ECNs) instead of stock exchanges. Trades run through the platform’s partnered ECN and buy and sell orders are matched by price.
Typically, there aren’t as many traders after hours. Not all platforms offer pre- or post-market trading and most active traders restrict their activity to regular market hours. Plus, there may be more competition from institutional investors after-hours. There are perks to after-hours trading, including the ability to quickly respond to changes in the market, regardless of time of day. However, for many investors, the risks — primarily low liquidity — outweigh the benefits.
What happens if I place a trade after my broker is closed?
It depends on your broker. If your trading platform allows after-hours trading, your order is submitted. If your platform doesn’t offer extended hours, your order will be executed at market open the following trading day.
Some orders are riskier than others when executing an after-hours trade. A market order instructs your broker to buy or sell stock at the prevailing market price: While you have no control over the price, trades are executed quickly. Market orders placed after the market closes are executed the following morning.
The risk of placing a market order after the market closes is that if anything happens overnight to affect the stock price, you could face a drastic loss.
To mitigate this risk, you could opt for a limit order: You tell your broker what price you’re willing to buy or sell and your order is only executed if those conditions are met. The trouble with limit orders is that the trade isn’t guaranteed — if the stock never hits the price you specify, the order won’t be executed.
Can you buy stocks on the weekend?
Thanks to the time difference, it’s possible for Canadian investors to trade in Australian and Asian markets on Sunday evenings.
Traders can also use electronic communication networks (ECNs) to trade on the weekend in the same way after-hours trades are conducted during the week. The network attempts to match potential buyers and sellers based on the trades they want to execute, but fills aren’t always possible — or profitable.

Pros and cons of after-hours trading
Pros
Convenient. Schedule restrictions and daily activities may limit an investor’s ability to execute trades when the market is open. After-hours trading allows investors to trade at a time that may be more convenient for them.
Ability to react to news. After-hours trading offers investors the opportunity to react to important news events before markets open or after they close. Earnings reports, economic indicators and breaking news all have the potential to impact the market after hours.
Competitive pricing. After-hours volatility tends to lend itself to increased risk, but this volatility can also work in a trader’s favor if stock prices move in an advantageous direction.
Cons
Less liquidity. Since fewer trades are executed after hours, it’s more difficult to buy and sell shares.
Wide spreads. After-hours trading tends to have wider spreads between bid and ask prices. For traders executing limit orders, this could mean fewer trades.
Order limitations. Most brokers don’t allow traders to swap mutual funds, bonds or options after hours, limiting trades to the buying and selling of stocks. Stop orders or all-or-none orders are also prohibited after hours, restricting traders to unconditional limit orders.
Extra fees. Some brokerages charge additional fees on after-hours trades.
Bottom line
After-hours trading comes with unique benefits and risks. Investors have the opportunity to react to news events and trade at a time that’s potentially more convenient — but reduced trading volume means more volatility, wider spreads and ultimately, greater risk.
If you’re interested in after-hours trading, find a brokerage account that offers extended hours alongside the features best suited to your investment goals.
