Understanding pre-open market session

The pre-open market session refers to the period before the regular market hours begin, during which the trading of securities takes place. It is a time when market participants, such as traders and investors, can place orders for securities that will be executed when the regular market opens. During this session, the prices and volumes of securities can be more volatile and less liquid than during regular market hours. This is because of less trading activity and liquidity in the market during this time, which can lead to wider bid-ask spreads and greater price fluctuations.

The pre-market open session is of short duration, typically lasting for 15-30 minutes. The window can be useful for market participants who want to make trades before the regular market opens. But, it can also be riskier due to the increased volatility and low liquidity. Some investors may prefer to avoid the pre-open market session and wait for the regular market hours to begin before making trades. However, for those who can stomach increased risk and volatility, the pre-open market session can be an opportunity to gain an advantage in the market.

Now, we will discuss some of the downsides of pre-market sessions.

Poor liquidity

Unlike regular trading hours that see the participation of many traders and investors, the pre-market session witnesses a much lower volume of stock purchases and sales transactions. Hence, the amount of money traded pre-market is often a small portion of what is traded during the main session. Due to the low amount of trades, there is less liquidity, leading to higher volatility levels and wider bid-ask spreads.

Price uncertainties

The pre-market price of a stock may be quite different from its market price later in the day. Pre-market stock prices might only reflect prices from one or a small number of electronic communication networks (ECNs). During normal trading hours, traders will have access to stock prices provided by several exchanges and ECNs, allowing for more efficient price discovery.
