Pre-Market and After-Hours Trading

Most stock exchanges in the US typically open for 5-7 hours during weekdays. The New York Stock Exchange (NYSE), Nasdaq (NASDAQ), and Toronto Stock Exchange (TSX) share similar trading hours: from 7:00 PM and 1:30 AM IST, from Monday to Friday. This US stock market time is exclusive of the days when the stock market remains closed.

The economy isn’t bound by such hours and the necessary market shifts can take place anytime. This factor and the advancements in electronic trading encourage the markets to permit trading beyond regular hours. If you trade outside of the regular trading hours, it is called after-hours and pre-market trading. The pre-market trading time is from 1:30 PM to 7:00 PM IST on weekdays. The after-hours trading begins at 1:30 AM IST and runs up to 5:30 AM IST.

On another note, the five major technological corporations which are listed under the US stock exchange are known as ‘FAANG stocks’: Meta Platforms Inc. (formerly known as Facebook),, Apple Inc., Netflix Inc.

How It Works

Pre-market and after-hours trading are extended trading sessions that occur outside the regular trading hours of the stock market. Here's how they work:

Regular Trading Hours: The regular trading hours of most stock exchanges, such as the New York Stock Exchange (NYSE) and NASDAQ, are typically from 7:00 PM to 1:30 AM IST Monday through Friday.

Pre-Market Trading: Pre-market trading takes place before the official opening of the regular trading session. It allows investors to trade securities before the market officially opens. The pre-market trading hours can vary depending on the exchange but generally start as early as 1:30 PM IST and extend up until the regular market opens.

After-Hours Trading: After-hours trading occurs after the regular trading session ends. It allows investors to continue trading securities even after the market has officially closed. The after-hours trading hours also vary depending on the exchange but can extend until 5:30 AM IST or later.

Participation and Platforms: Pre-market and after-hours trading are typically available to individual investors, institutional traders, and market makers who have access to electronic trading platforms that support extended trading hours. These platforms may include direct market access (DMA) systems, electronic communication networks (ECNs), or specific brokerage platforms.

Liquidity and Volatility: It's important to note that pre-market and after-hours trading tend to have lower liquidity compared to regular trading hours. This lower liquidity can result in wider bid-ask spreads and increased price volatility. As a result, prices during extended trading sessions may not accurately reflect the prices that will prevail during regular market hours.

Order Types: During pre-market and after-hours trading, you can typically use various order types, such as market orders, limit orders, and stop orders. However, it's important to be aware of any limitations or restrictions that your brokerage or trading platform may impose during these sessions.

It's crucial to approach pre-market and after-hours trading with caution and understand the potential risks involved. If you're new to trading or unfamiliar with extended trading hours, it's advisable to consult with a financial advisor or do thorough research before participating.

Accessing Extended Hours Market Data

Accessing extended-hours market data requires the use of specialised trading platforms or market data providers that offer coverage of pre-market and after-hours trading sessions. These platforms or providers aggregate and distribute real-time quotes and trade data from the extended trading hours. They may offer features such as customizable watchlists, advanced charting tools, and news feeds specific to after-hours trading activity. Traders and investors can utilise these platforms to analyse extended hours market data, monitor price movements, and make informed trading decisions based on the information available during pre-market and after-hours sessions.
